Veterinary Technicians

Theresa Adomis

Theresa Adomis, Veterinary Technicians at York Animal ClinicTheresa grew up on a small rural farm in York, PA. This is where her love for animals of all kinds started. Caring for and feeding all of the animals was never considered work to her. She preferred cleaning the barn over housework any day.

With this love of all animals, it was fitting that she followed her heart and worked taking care of them. Starting as a kennel attendant in 1991, she learned the ropes and advanced to an Assistant followed by a Technician.

Theresa lives in the same neighborhood she grew up in, sharing her home with her 3 dogs (Timber, Grover, & Sammy), 3 cats (Ilean, Shasta, & Daisy), horse (Hoss), donkey (Suzie), some chickens, and whatever else comes along in need of a home.

Theresa’s hobbies include gardening, trail riding, hiking, and camping with her horse and dogs.
