Monthly Drawing

We like to acknowledge clients who take the time to leave reviews about us on various websites. Every month we put their names in a "hat" and draw a winner, who gets a $50 credit at Vernon Hills Animal Hospital. The name drawn for October was Harmeet Singh and his 6 year old beagle, "Max".
Thanks Harmeet!

 Dr. Tonya Gray

While Dr. Cheung is temporarily out of the office on maternity leave, Dr. Tonya Gray will serve as our relief veterinarian.


During her high school years Dr. Gray became very interested in becoming a veterinarian. She loved science, and wanted a career in which she could continue learning and help people take care of their pets. She is a 1998 graduate of the School of Veterinary Medicine at the University of Illinois. She has a special interest and extra training in veterinary dentistry.


Dr. Gray is married with three sons, 13, 15, and 17 years old. All three are involved with sports; she is definitely a football mom! She also has a 3 month-old Rottweiler puppy named “Mariah” and a 5 year-old bearded dragon, “Tarzan”.


When she isn’t working, Dr. Gray enjoys cooking for her family and going to her kids’ wrestling tournaments and football games. She likes to weight train, and she’s also a runner. 


Please welcome Dr. Gray to our practice!
