Welcome to Glastonbury Veterinary Hospital

Glastonbury Veterinary Hospital has been a part of the community since 1965. In January of 2023 the practice was sold to Dr. Jason Haviar and his wife Dr. Griffin O’Connor both current residents of Glastonbury, CT.

We are dedicated to providing progressive veterinary care for our patients. Our goal for every pet is a lifetime of health through proactive, preventative care and dedicated veterinary service. We understand the special role your pet plays in your family. As a partner in your pet's health care, we are committed to treating your pet with the same care that we give our own pets.

We offer a variety of excellent veterinary services such as pain management, laser therapy and surgical services to name a few. Please go to our Services Offered page to see a full list. These services allow us to offer the very best care for your pet. In the event we are unable to give your pet the care required we will refer you to a highly qualified Veterinary Hospital better able to meet your pet's specific needs.


While keeping pets healthy is our number one priority, we are also dedicated to progressive veterinary care, strengthening the pet-owner bond and providing the kindest, most compassionate service to our clients.

Your pet is part of your family and at Glastonbury Veterinary Hospital you are part of ours!

We always welcome new clients! Please go to our New Clients page for more information and to fill out a New Client Form.

Jason purchased Glastonbury Veterinary Hospital in 2023. He has lived in Glastonbury for 10 years with his wife (also a vet in town) and two children. Dr. Haviar has been active with youth sports and supporting his community through coaching GBA and Glastonbury Little League.  Dr. Haviar enjoys surgery, dentistry and medicine cases.

She spent the first 10 years of her veterinary career practicing at Suffield Veterinary Hospital.  When she realized it was time to move closer to her family, she moved to Glastonbury Animal Hospital.  It has always been a dream of Dr. O'Connor to own a veterinary practice so when Dr. Laura Sprague invited Griffin and her husband Jason, they graciously accepted this offer. When she is not working Dr. O'Connor can be found cheering her children on from the sidelines of local sporting teams.  She also shares her home with two Rhodesian Ridgebacks, Bodhi and Sparkle as well as her rescue cat Sushi.
