Dr. Lisa Connor


 Dr. Connor joined the AAH team early in the fall of 2020 after studying at the Chi Institute for her Certified Veterinary Acupuncture certification. Born and raised in Southeastern Massachusetts, Dr. Lisa initially obtained her business degree and held several successful administrative roles in the fields of venture capital, emergency medical transportation, and general health care. After the tragic events of 9/11, she decided to pursue her childhood dream of becoming a veterinarian. In 2004, she moved to Rhode Island and enrolled the following year into the University of Rhode Island's veterinary medicine program. 

Dr. Connor obtained her Doctor of Veterinary Medicine from the Atlantic Veterinary College of Prince Edward Island, Canada.  She initially worked with companion animals and horses. She has particular interest in veterinary nutrition, dental prophylaxis, and alternative therapies such as acupuncture, chiropractics and laser therapy. Outside of work, Lisa enjoys time at home on her family farm with their Great Pyrenees dogs, cats, and three horses.  Dr. Connor is an active member of the Great Pyrenees Club of America and enjoys attending local and regional AKC dog shows.  She also enjoys gardening and culinary arts.


A Personal Approach to Pet Care

At Apponaug Animal Hospital, we understand that every pet is unique, and so is the bond you share with them. That's why we believe great veterinary care goes beyond treating an illness or providing a routine checkup-it's about getting to know each pet and the family who loves them.

We strive to create a welcoming environment where you feel comfortable asking questions, sharing your concerns, and being involved in decisions about your pet's health. We take the time to listen, explain care options, and help you understand what's best for your individual companion.

Whether your pet is visiting us for a wellness exam or needs additional medical attention, our goal is to treat them with compassion, respect, and the thoughtful care they deserve. We're grateful for the trust you place in our team and are proud to be part of your pet's healthcare journey.
