Dr. Nicholas Chuff, Owner
Dr. Patricia Clark
Dr. Clark earned her B.S. with honor and distinction from Cornell’s College of Agriculture in Animal Science and her D.V.M. from Cornell’s College of Veterinary Medicine. She has been practicing small animal medicine for over 25 years, with the majority of that time at German Flatts Veterinary Clinic. Her greatest satisfaction comes with treating the more difficult cases and reuniting pets with their families. Her goal has always been to treat her patients’ medical and surgical needs as she would treat her own pets.
Dr. Clark lives on a small farm with her husband, John. They have 2 grown daughters, Mary and Andrea. The Clark family raises and shows purebred Oxford and Southdown sheep.
Dr. Clark is a member of AVMA, NYSVMS & CNYVMA and also a member of the New York State Academy of Veterinary Practice.

Kris Lennox, CVPM - Practice Manager
Kris joined German Flatts Veterinary Clinic in 1982, working evenings and weekends as a receptionist/assistant. After earning her AAS in Veterinary Science Technology from SUNY Canton in 1987, she passed her New York State Boards and became a Licensed Veterinary Technician (LVT). Gradually, Kris took over more of the office management and financial responsibilities for the hospital, freeing up Dr. Chuff to focus on practicing veterinary medicine. In 2001, Kris received her Certification in Veterinary Practice Management (CVPM), an international recognition. Kris lives in Ilion and has two sons, Josh and Mike, who is currently serving with the United States Air Force.
