 Dr. Isaac Angell is a native of the Hudson Valley, born and raised on Bentley Farm in the town of Stanford, NY. It was there Dr. Angell’s love of animals flourished. Dr. Angell states, “It was raising and training oxen that taught me about persistence and consistency. It was riding and driving the horses that taught me about patience and calmness. It was showing our Ayrshire cattle and winning a prize that taught me to take pride in my work.” Growing up, one of Dr. Angell’s life aspirations and goals was to become like his family’s longtime veterinarian, Dr. Douglas Hart. It was Dr. Hart who mentored and guided Dr. Angell through vet school and ultimately offered him a job with Pine Plains Veterinary Associates upon graduation from Cornell University College of Veterinary Medicine. 

​​Dr. Angell received his undergraduate degree in Animal Science from Cornell University College of Agriculture and Life Sciences. During his undergraduate career he was inducted into the Phi Theta Kappa Honors Society and the Cornell Tradition Society. He received the DUE Award for academic excellence,  

and the American Dairy Science Association Award. He had the privilege of participating in Cornell Dairy Fellows program.  
​In Veterinary School, Dr. Angell received the Francis H. Fox Scholarship, Dr. Ronny Miller Memorial Scholarship, and the Dutchess County Dairy Committee Scholarship. He dedicated a summer to enroll in and graduate from the Summer Dairy Institute. He graduated from Cornell with his Doctorate of Veterinary Medicine in 2011. Believe it or not Dr. Angell, Dr. Hart, and their predecessor Dr. Webster all had a professor in common at Cornell: Dr. Fox.  

Dr. Angell is a member of the American Association of Equine Practitioners, the American Association of Bovine Practitioners, the American Veterinary Medical Association, and Eastern New York Holstein Club.

Dr. Angell’s passion for large animals led him to buy the large animal division of Pine Plains Veterinary Associates in 2014 and start his own veterinary practice, Bentley Veterinary Practice, which is solely dedicated to farm animals. 

When Dr. Angell is not working for the Veterinary Practice, he loves spending time with his wife and daughters. Together, they enjoy working together on their farm and tending to their herd of cattle. 



Dr. Julie Clas grew up near Rochester, NY. Although she did not grow up on a farm, her interest in animals drew her to work on a large dairy in high school and college. It was in this environment that she took the night shift milking, calved cows in the maternity pen, and learned the intricacies of a working farm.

Dr. Clas attended the College of Agriculture and Life Sciences at Cornell University where she majored in Animal Science. From there she continued onto Cornell’s College of Veterinary Medicine. It was here that her interest in equine medicine budded. She worked as an emergency surgery tech at Cornell’s Equine Hospital and assisted with many colic surgeries. While fostering her interest in Equine medicine she also pursued more training in cattle medicine, taking an advanced summer course in dairy cow management called the Summer Dairy Institute.

Graduating from Cornell in 2010, she took a job in Franklin County, NY where she worked until she joined Bentley Veterinary Practice in 2016. It was there that her interest in equine reproduction, equine dentistry, cattle herd health and reproduction, and neonatal care flourished. It was through her abilities and 
passions that the practice went from being a bovine centered practice, to a practice that encompassed a considerable equine focus as well as turning more attention to sheep, goats, and pigs.

Dr. Clas has many veterinary proficiencies, but what makes her impressive is her ability to relate to people: always willing to listen and have a conversation in a relatable manner.

Dr. Clas is an active member of the American Association of Equine Practitioners, American Association of Bovine Practitioners, and the American Veterinary Medical Association.

When not engaged in the caring for the animals, Dr. Clas might be found staying busy with her two young kids, running, cycling, or even horseback riding. ​​​




Dr. Isabelle Louge grew up in Ithaca, NY and Rennes, France. Her interest in animals began in spending her summers on her grandmother’s cow-calf operation in Najac, Aveyron and grew through riding at La Petite Hublais, Forêt de Rennes, France. During grade school she worked on therapeutic riding farms and dairies around Ithaca. She completed her senior year of high school shadowing veterinarians at Cornell’s veterinary school and learning about forestry and natural resources as a part of the New Visions Life Sciences program.

As an undergrad in Animal Science at Cornell’s College of Agriculture and Life Sciences Dr. Louge worked as a riding instructor at Oxley Equestrian Center and did research on mastitis vaccines and the bovine immune system with Dr. Ynte Schukken. She also was an active member of the Cornell University Dairy Science club, even going with them to tour dairy operations in Italy.

At Cornell’s veterinary school Dr. Louge focused on large animal medicine, even receiving the Zoetis Clinical Proficiency Award in Dairy Production Medicine. She learned more about dairy management and medicine through working as a student chief for 

the vet school teaching dairy and attending Summer Dairy Institute. Dr. Louge became a published author while participating in the Veterinary Investigators Program through her work on hypocalcemia in Dr. Jessica McArt’s lab through a grant from the NIH, and Merial. Dr. Louge also volunteered yearly at the Hector Half Hundred endurance race in Hector, NY where she helped assess horses as they crossed check points and developed an appreciation for endurance racing.
