About Us

Many people make up the behind-the-scenes and front line activity at Vergennes Animal Hospital. From the minute you enter the hospital, any number of staff members will be there to assist you and your pets.

Meet Our Doctors!

Mark Basol, DVM, CVA

I have practiced and owned Vergennes Animal Hospital (VAH) since 1987. Over the years, the practice has changed in scope, however, the one constant is my commitment to the pets and their owners that we serve. I enjoy the pets and the people they come with – from the 5th generation Vermonter to the newly-arrived.

Growing up in a large farm family of six in eastern North Dakota I have always been connected to animals – large and small. We were blessed with great pets to play with, horses to ride, cows to milk, and an occasional pig to round out the menagerie. These experiences lead me to an animal science degree at North Dakota State University (go Bison!), then on to veterinary school at Iowa State University (go Cyclones!).

My veterinary career began in a primarily large animal practice in northeast Iowa. And while the town of Oelwein was good to us, my wife Julie and I were feeling the pull to find our forever home. It was the skiing that lured us to Vermont yet it’s the sailing that continues to make the summers so appealing to us.

Julie and I reside in North Ferrisburgh with our Stabyhoun dog, Dirk and foster cat named, Temp (short for Temporary). With 2017 marking our 30th year in Vermont, we remain committed to the community for which we live and work.

Greg Carlton, DVM

Dr. Greg Carlton is a native of rural North Carolina and joined VAH in 2013 right out of vet school. He received his Doctor of Veterinary Medicine from Purdue University after previously majoring in biochemistry at the University of North Carolina. His areas of veterinary interest include preventative medicine, internal medicine, and dentistry. Outside of work he enjoys fishing, hiking, obstacle course racing and spending time with his wife, Heather, and their five dogs.

Carrie Olson, DVM, CVA

Dr. Carrie Olson grew up in New Jersey with a variety of pets. She knew she wanted to be a veterinarian from the time she was young. She moved to New England to attend college at Tufts University, where she majored in biology and archaeology. After graduating in 2006, she continued to Tufts Cummings School of Veterinary Medicine where she worked in the busy emergency room as a student technician and was involved in the local animal-assisted therapy group.

After receiving her Doctor of Veterinary Medicine with honors in 2010, Dr. Carrie moved out to Seattle where she completed a yearlong internship in internal medicine, surgery, and emergency medicine. She spent a year working in an emergency and referral hospital in Seattle, then moved to a busy 24-hour general practice in Bellevue, Washington. After a time, she and her husband moved back home to the East Coast to be closer to her family.

Dr. Carrie is delighted to join the team at VAH. She enjoys the daily challenges of veterinary practice and loves helping clients build bonds with their pets throughout their lives. Her particular professional interests lie in internal medicine, infectious diseases, geriatric medicine, and critical care and she looks forward to expanding her knowledge as part of the VAH team.

When not working, Dr. Carrie likes to hike and cook with her husband, cuddle with her two cats, and take walks with her dog, Leo. She is looking forward to exploring the beautiful Vermont outdoors and the delicious local food scene.

Rebecca Sevy, DVM

Dr. Rebecca Sevy joined VAH in 2012 after completing a rotating small animal internship at Burlington Emergency Veterinary Specialists (BEVS) in Williston. Dr. Becca attended The University of Vermont as an undergrad with a major in animal science. Participating in UVM’s Cooperative for Real Education in Agricultural Management (CREAM) program cemented her dedication to veterinary medicine. She obtained her veterinary degree in 2011 from Western University of Health Sciences in Southern California.

Enjoying all aspects of companion animals lead her to pursue a general veterinary practice focus. She loves it all every day, particularly internal medicine, preventative health and pain relief management.

Attending UVM introduced Dr. Becca to Vermont and everything it has to offer. The state has just the right mix of environments – rural and city, companion animals, natural food, and friendly people. Her love stuck with her as she traveled to California, Colorado, and returned again after finishing vet school.

Dr. Becca lives in Charlotte with her husband Bryan, a dairy herdsman for a farm in Ferrisburgh. They have two young boys, Camden and Emmett, who love to visit the clinic. Along with some of Bryan’s cows, her dog Bree and cat Millie round out their family. Bree is a lovable mixed breed from the Franklin County Humane Society. Millie is a scared-y cat, part feral from the streets of California.

When not at the animal hospital, Dr. Becca enjoys to run, play with her boys and Bree, hike, read, and cook. Or maybe more accurately, eat yummy food!


Gemma Gerardi, DVM

Gemma was born in Scotland where she spent her early childhood years before moving to Stony Brook NY at age 8.
