Emily then relocated to Ithaca, NY to attend Cornell University’s College of Veterinary Medicine. She graduated in 1997 with her Doctor of Veterinary Medicine degree (DVM). After graduation Dr. Allen had the unique opportunity to work at an aquatic animal diagnostic lab in Maine, primarily service the Atlantic salmon farming industry. In 1999, Dr. Allen moved back to Western Massachusetts to join Dr. Constant at Westover Animal Clinic.
