Franca DiFilippo, DVM

Franca DiFilippo, DVM is originally from Rochester, New York, and attended the Rochester Institute of Technology (RIT). She graduated with honors in 1993 with a BS in biology and a minor in psychology.

After graduating from RIT, Dr. DiFilippo attended the New York State College of Veterinary Medicine at Cornell University as a member of the first class at Cornell to learn veterinary medicine via the Learning Based Curriculum. Upon graduating from Cornell in 1997, Dr. DiFilippo participated in a small animal medicine and surgery internship at the well-known Angell Memorial Animal Hospital in Boston, Massachusetts, where she developed her love of small animal internal medicine and critical care. Angell was featured in Life magazine, on the "Good Morning America" show, and is the subject matter of the book Animal Hospital. After finishing the Angell internship, Dr. DiFilippo returned to upstate New York and began working as an associate veterinarian at the Orchard Park Veterinary Medical Center in October 1998.

She was a founding member of the Pre-Veterinary Club at RIT. While attending RIT, Dr. DiFilippo took part in karate classes, where she met her future husband who was a hotel management major at the time. While at Cornell, she developed an interest in exotic animal medicine by volunteering in the Wildlife Clinic there and attending both Aquavet courses in Woods Hole, Massachusetts, focusing on aquatic animal medicine. Aquavet provided some of her favorite memories from veterinary school. She also took part in an externship at the National Aquarium in Baltimore and helped perform many unique tasks, such sonograms on stingrays, collecting blood from green tree anoles, and preparing meals for the cetaceans, among other things. It was during veterinary school that she discovered another passion—white water rafting—while attending an AAZV conference in Pittsburgh, Pennsylvania, and one of the activities was rafting Class III and IV rapids on the Youghiogheny River. She has loved it since and does not get to enjoy it nearly as much as she would like.

Dr. DiFilippo chose her profession not only for her love of animals, but also due to her love of learning, as there is no shortage of either in veterinary medicine. She hopes to continue to serve animals and their people for many years to come while continuing to develop as both a veterinarian and a person.

Dr. DiFilippo lives with her husband, son, and daughter, along with two cats and two dogs. Dr. DiFilippo cherishes the time with her family, especially while enjoying some of their favorite activities together—hiking/nature walks, rafting, biking, and traveling. Outside of her busy work schedule, Dr. DiFilippo also serves as a Girl Scout troop leader, complete with cookie sales, camping, crafts, and service projects. Her two cats, Mayapapaya, a female orange tabby, and Ponyo, a male grey tabby, and dogs, Buffy, a female Jack Russell terrier/Chihuahua mix, and Spike, a male Jack Russell terrier round out the family. She is thoroughly proud of her "girls," some of who have been with her for going on four years now (her daughter, of course, has been with her a little bit longer than that!).

James Fingeroth, DVM, Diplomate ACVS

James Fingeroth, DVM, Diplomate ACVS, hails originally from New York City, but spent his college years in upstate New York, earning his bachelor of science degree at Hobart College in Geneva, and then his doctorate from the Cornell University College of Veterinary Medicine in Ithaca.

After graduation from veterinary medical school, Dr. Fingeroth was selected as an intern/first-year resident at New York City's prestigious and world famous Animal Medical Center (AMC). He was then asked to stay on at the AMC for his surgery residency and completed his second year of training at the AMC. Dr. Fingeroth then had the opportunity to expand his horizons by completing the final two years of residency training in small animal surgery at The Ohio State University in Columbus, Ohio. Upon completing his formal residency, Dr. Fingeroth remained two more years at Ohio State, joining the faculty as an adjunct assistant professor of surgery. In 1988, Dr. Fingeroth passed the rigorous American College of Veterinary Surgeons (ACVS) certifying examination in veterinary surgery, making him at that time one of only 350 board-certified veterinary surgeons in the world. Only veterinarians who have completed a residency in surgery and passed the certifying examination are qualified to be called specialists in veterinary surgery. That same year, he relocated to Rochester, New York, where he helped found and establish Veterinary Specialists of Rochester.

Over the next 20 years, he helped recruit numerous other specialists to upstate New York and also helped train dozens of graduate veterinarians through internship and residency programs. He is proud to count a number of board-certified specialists in surgery, neurology, internal medicine, oncology, emergency medicine, pathology, dentistry, and ophthalmology among those he helped to train early in their post-graduate careers.

Dr. Fingeroth decided to pursue veterinary medicine as an ideal way to combine his compassion for and wanting in general to help animals, with his interest in science and medicine. He believes that the pursuit of post-graduate education and training through internship, formal residency, and time spent in a faculty position had the greatest influence on his career. These experiences not only provided him with skills and knowledge well beyond the basic veterinary degree, but also ingrained lifelong habits of keeping up with state of the art and seeking better solutions to problems encountered in the daily practice of veterinary medicine. The post-graduate experience also helped him to forge close relationships with leading specialists from around the globe, providing ongoing intellectual stimulation and camaraderie that carries on even decades later.

Dr. Fingeroth joined the Orchard Park Veterinary Medical Center in 2009 as the senior staff surgeon three days a week. He is a nationally and internationally recognized expert in various surgical fields, including orthopedics, neurosurgery, endocrine, and oncological (cancer) surgery. In addition to his work at Orchard Park Veterinary Medical Center, Dr. Fingeroth is a senior consultant to the Veterinary Information Network (VIN), which is an online consulting service for veterinarians around the world. He serves as reviewer for several major scientific journals, contributes chapters to a large number of widely read veterinary textbooks, is the author or co-author of numerous publications in scientific journals, consults with various industry partners in developing new surgical techniques and devices, and is the author/editor of the first ever veterinary textbook focused on intervertebral disc disease in dogs and cats.

In addition to his own clinical duties at Orchard Park Veterinary Medical Center, Dr. Fingeroth provides ongoing mentoring to Dr. Paul Kloc, our residency-trained veterinarian who also limits his practice to surgery, as well as providing consultations on surgical issues to our associate staff veterinarians in the community portion of our practice. He works closely with Dr. David Brummer, practice partner and board-certified internist here at the Orchard Park Veterinary Medical Center, in providing state-of-the-art specialty services to our referral and community practice, as well as consulting on emergency cases. Dr. Fingeroth prides himself on his ability to help his patients through his surgical skills but he takes equal pride in assisting his clients by providing candid, easy-to-understand advice involving surgery, as well as finding ways to help pets without resorting to surgery.

Dr. Fingeroth is available by appointment for consultation on a wide range of surgical or potential surgical problems. A referral from a primary care veterinarian is required for his consultation and surgical services. His surgical expertise includes joint replacement (he has been performing total hip replacements since 1984), knee surgery, fracture repair, spinal and brain surgery, and a wide variety of thoracic and abdominal surgeries. He is also respected as an oncologic surgeon, including major tumor resections and reconstructions for maxillofacial and oral tumors, chest tumors, and other complex cases. Dr. Fingeroth's continuing goals are to provide the best service he can to his referred clients and to try to improve the overall level of quality of veterinary services offered at Orchard Park Veterinary Medical Center and to the western New York community.

On a personal note, Dr. Fingeroth lives in Mendon, New York, with his wife, Robbie, and a menagerie that includes a large number of canines, cats, horses, and an assortment of rodents and fish. He is an avid Native American horseman and has been a licensed pilot since 1973. He enjoys flying for pleasure, business, and also provides charity flights for people through Angel Flight/Patient Airlift Services and for animals through Animal Rescue Flights and People N Paws. In his spare time when not flying or horseback riding/training, Dr. Fingeroth enjoys reading, music, native craftwork, hiking, and solitude.

OPVMC is happy to have high quality rapid telepathology as yet another diagnostic tool in the cutting edge medicine that we offer. Having access to Dr. Fish as an associate specialist in clinical pathology allows OPVMC to submit cytologogical slides electronically to him directly from our microscope , typically with result turnaround times of 10 minutes to 2 hours. As such we have a diagnosis much more quickly than we have ever had in the past, allowing us to in turn start a treatment plan much more quickly as well.

L. Mark Hedges, DVM

L. Mark Hedges, DVM, grew up in Ohio, north of Columbus. He received his Doctorate of Veterinary Medicine from The Ohio State University. Dr. Hedges joined the Orchard Park Veterinary Medical Center early on when the practice was still owned by Jack Laurie, DVM. Dr. Laurie was his first mentor and a gifted surgeon who taught Dr. Hedges surgical techniques and inspired and trained him to perform more advanced surgeries. In 1995, Dr. Hedges became one of the partners of the current practice. He is a now a primary health care provider for his patients, but still enjoys performing more complicated surgeries and is the practice's "back-up" surgeon when needed. Dr. Hedges says that it is his partners, Dr. David Brummer, ACVIM, and Dr. Susan Metzger, DVM, who further influenced him to stay on as a partner because of their knowledge, integrity, and dedication to the profession and practice of veterinary medicine. Dr. Hedges is very proud to have played a small part in the growth and reputation of the current practice.

Dr. Hedges was inspired to become a veterinarian by his father, who was a high school vocational agriculture teacher. When young, Dr. Hedges used to ride around with him when he visited his students during the summer months to check on their livestock projects. He loved watching his father work with the animals and the students and was inspired by the work. When he was old enough, Dr. Hedges raised sheep on his grandmother's farm along with a pony and cared for his family pets at home. Combining his love for animals and his deep interest in science and biology seemed a natural lead in to veterinary medicine.

Dr. Hedges' personal accomplishment that he is most proud of is of the family that he and his wife, Grace, have been blessed with. He has four wonderful daughters and two grandchildren, with another on the way. Dr. Hedges loves gardening and helping his daughters on their home projects as well as his own, as he fixes and plays caretaker for a cabin on a lake in Quebec, Canada, he inherited, that always needs work! All of his pets over the years have been rescued strays or adopted because of underlying health issues. His current canine is Buddy (such an original name), an "atypical" Cavalier King Charles Spaniel. Buddy loves to play ball and to guard and protect his beloved master and home from all "wanted" and "unwanted" visitors. Trixie is his other spoiled pet. She is your typical cat that lounges wherever she wants and demands (and gets) to be fed whenever she wants. Dr. Hedges donates to many various animal health agencies and is very active in his local church.

Erin Klene, DVM

Erin Klene, DVM, was born and raised in Manchester, New Hampshire. She received her bachelor's degrees in biology and animal science from the University of Delaware. She then received her doctorate from the Cornell College of Veterinary Medicine in Ithaca, New York. Dr. Klene moved to the western New York area after graduation and joined the Orchard Park Veterinary Medical Center.

Dr. Klene's love of animals and combining it with veterinary medicine seems to run in her family. Her grandfather and great-grandfather were also practicing veterinarians. Her grandfather was willing to allow her to ride along on farm calls when she was a very young girl, fostering an interest that would lead to a decision to pursue a career in veterinary medicine.

Dr Klene did forgo the "farm calls" and limits her practice to small animal pets here at Orchard Park Veterinary Medical Center. She enjoys the practice's unique blend of primary care general practice, emergency, and specialty care that we provide. Dr. Klene loves the outdoors and enjoys soccer, running, biking, and hiking, especially when the family and family dogs tag along.

Paul A. Kloc II, MA, DVM

Paul A. Kloc II, MA, DVM, grew up in West Seneca, New York, and graduated from St. Francis High School. He received his undergraduate degree, a bachelor of science in animal science, from Cornell University in Ithaca, New York. Dr. Kloc obtained a master's degree in biology while working with leatherback sea turtles at the State University College at Buffalo. He attended and received his doctorate in veterinary medicine at Ross University School of Veterinary Medicine in St. Kitts, West Indies. As part of his veterinary medical training, he received his clinical training at Cornell University. After a year in private practice, he completed his internship in small animal medicine and surgery at Angell Memorial Hospital in Boston, Massachusetts. Dr. Kloc then completed a surgical residency at Pennsylvania Veterinary Specialty and Emergency Associates at Hickory Veterinary Hospital in Plymouth Meeting, Pennsylvania. He then moved to the western New York area and joined the Orchard Park Veterinary Medical Center, where he consults as a referral veterinarian and performs specialized surgery.

Dr. Kloc has always had a strong interest in learning and working with animals from a young age. Dr. Kloc said he always knew that he wanted to do something in the sciences (medicine, research, etc.) but that he didn't know exactly what it was going to be until he learned about veterinary medicine from the veterinarians that took care of his dogs and horses. Dr. Kloc reveals that early on the veterinarians that took care of his animals were the most influential in his decision to pursue this career. As he was finishing middle school and entering high school, his interest and abilities in science grew stronger and it was then that he knew that it was veterinary medicine that he was most interested in. Dr. Kloc did have an opportunity to pursue a research career working with sea turtles during his master's degree training. This further confirmed his desire to work with animals and his resolve to pursue veterinary medicine. Once in veterinary school, the surgeons that he interacted with guided his decision to pursue and limit his practice to surgery.

Dr. Kloc is proud to have completed the educational training that he pursued, but he is most proud of the care and hope that he is and has provided to the animals and their families for whom he has performed surgical procedures. His current responsibilities at Orchard Park Veterinary Medical Center are limited to surgery. His interests include general surgery, orthopedics, and neurosurgery. Dr. Kloc is certified to perform Tibial Plateau Osteotomy (TPLO), Tibial Tuberosity Advancement (TTA), and BioMedrix total hip replacement. Dr. Kloc's goals professionally are to eventually attain Diplomat Status in the College of Veterinary Surgeons and expand his surgical capabilities to include arthroscopy and laparoscopy.

Dr. Kloc lives with his wife, Kelly, and their four children in East Aurora, New York. He is a native sports enthusiast and enjoys watching the Buffalo Sabres and the Buffalo Bills. In the last year, the Klocs have added Abigail, a purebred English bulldog to their family. On a personal note, Dr. Kloc would also like to learn to fly and attain a pilot's license.

Susan Mercer, DVM

Susan Mercer, DVM, obtained her undergraduate degree, a bachelor of science in animal science, from the University of New Hampshire. She received a master's degree in veterinary parasitology from Texas A&M. While working toward her master of science degree in veterinary parasitology, Dr. Mercer explored tick-borne diseases in dogs and this inspired her to seek more structured information than pursuit of her master's degree afforded her in hopes of better understanding the disease processes and how better to help dogs afflicted with tick-borne diseases. Therefore, Dr. Mercer then continued her education and obtained her Doctorate in Veterinary Medicine from The Ohio State University, where she was named to Phi Zeta, a national honor society upon graduation. After a brief stint as a large animal veterinarian, she now exclusively provides emergency care to pets on three of the overnight shifts, and has done so since joining Orchard Park Veterinary Medical Center in 1991. She is a member of the AVMA, VECCS, NYSVMS, and AAHA.

Dr. Mercer always had a large menagerie of pets while growing up, and as she also worked for a veterinarian (who was also her Sunday school teacher) everyone brought her all the strays and injured animals to care for, much to her father's dismay! She is still taking care of sick and injured pets at night and feels this is her true calling and niche. She is honored to work with such a great medical team, especially at night, and is truly thankful to the clients who trust her to care for their pets in their crisis hour. Dr. Mercer says she does not know what she would do without emergency medicine that keeps her mind fresh and engaged.

Dr. Mercer is an outdoor enthusiast, and you will find her enjoying the outdoors year round. She loves hiking, cross-country skiing, and snowshoeing. Dr. Mercer also competes internationally as an amateur woman atlatlist. She is proud of her ranking as an atlatlist (a specialized dart thrown with a spear), and she is one of the top 10 women in the world for the last three out of four years. Read more about the World Atlatl Association. This is a great accomplishment, as her father used to say she "couldn't hit the broadside of a barn"! When forced to be inside, she loves to read, stretch with yoga, or relax with tai chi and qigong. Someday she would like to retire to more fully take advantage of the natural outdoors and travel that she loves.

Upon graduation, she joined the Orchard Park Veterinary Medical Center, and in 1995 she became one of the three current partners.

Dr. Metzger decided to become a veterinarian when she was about 10 years old. Her mother is a great animal lover, and their home was always a place where the neighborhood kids brought sick, injured, or orphaned animals. While in high school, she developed a strong interest in science, so a career in veterinary medicine just seemed to make sense.

When not working, Dr. Metzger loves the outdoors and enjoys hiking, biking, skiing, and gardening. Her goal is to still enjoy all these things when she is 80! Her family consists of her husband, Jay; their two sons, Jon and Matthew; and two "slightly used" felines.

Michael Rickwald, DVM, attended the University of California–Davis for his undergraduate bachelor of science in animal science with a minor in statistics and graduated with high honors. He attended the same university for his doctorate degree in veterinary medicine and graduated as a member of the Phi Zeta honor society.

From an early age, he was always eager to help his mother when she cared for the family's animals. As he matured, he remained very interested in animal health and welfare so the field of veterinary medicine seemed like a good fit for a career. While no one experience was the major influence on his decision to become a veterinarian, his volunteer experiences shaped his future, as well as an internship at a large referral and emergency hospital in New York City. Dr. Rickwald also credits many amazing and knowledgeable teachers that he had along the way for bringing him to where he is now.

Dr. Rickwald comes from a small family in California. Dr. Rickwald enjoys outdoor activities like hiking, camping, and biking and is not ashamed to admit he likes video games too! Dr. Rickwald has a lovely cat, Jasmine, and a ball python, named Tonga, as pets. He has volunteered for Rural Area Veterinary Services (a branch of the Humane Society Veterinary Medical Association) both as a veterinary student and a veterinarian. He has also worked for the SPCA and volunteered in the past for World Spay Day.

He worked part-time as a veterinarian and as a professional ski patroller at the Canyons Resort in Park City, Utah, during that time.

He very much enjoys, and feels lucky, working with such a great team of talented and compassionate people. He takes great pleasure in reuniting once sick pets with their owners—the happy endings!
