Campus Phone:


Lois Wetmore, DVM, MS, ScD, DACVAA, Section head of the Anesthesia and Analgesia service at Cummings School of Veterinary Medicine and is a diplomate in the American College of Veterinary Anesthesia and Analgesia. She graduated from Colorado State University Veterinary School in 1982 and did her residency training at Michigan State University where she also earned a MS degree in Veterinary Sciences. Dr Wetmore continued her research training at Harvard’s T.H. Chan School of Public Health where she received a doctoral degree in 1993. Dr. Wetmore has been a member of the Cummings faculty for the last 23 years where she focuses on teaching DVM students in didactic courses and clinical rotations, providing anesthesia service to the large and small animal hospitals, and doing research studying genetic-related differences in how companion animals respond to analgesia drugs.
