veterinarianBruce Berridge, D.V.M., Associate Veterinarian
Dr. Bruce Berridge received his bachelor of science degree from Michigan State University in 1970 and his Doctorate of Veterinary Medicine degree from Michigan State Universities College of Veterinary Medicine in 1973. Soon after getting his DVM, Dr. Berridge married his sweetheart, Gina, and they moved to Massachusetts, where he practiced veterinary medicine at the Belmont Animal Hospital (1973–1975) and the Woburn Animal Hospital (1975–1977). In June 1977, Dr. Berridge purchased the Duxbury Animal Hospital from Dr. Benjamin Dow and provided family-based veterinary care in that capacity to the Cape and South Shore communities for more than 36 years before handing the reigns over to Dr. Hebert. A member of the Massachusetts Veterinary Association (MVMA), Dr. Berridge attends several continuing education conferences a year to advance his skills and knowledge base in his primary interests: internal medicine and soft tissue surgery. His additional professional memberships include the American Animal Hospital Association (AAHA), earning Duxbury Animal Hospital accreditation in recognition of providing high-quality care, and the American Veterinary Medical Association (AVMA).

From 2003 to 2014, she provided office management, education and outreach, and project management for the Southeastern Massachusetts office of The Nature Conservancy. While there she worked on Freshwater, Marine, and Terrestrial initiatives and land protection/stewardship for southeast Massachusetts. She committed herself to conservation while working at The Council of State Governments and discovering that among all the public policy areas, environmental awareness was the most important and least prioritized.

508-743-9888 x308
Sea Rogers Williams is an aquatic and companion animal veterinarian who lives on Martha’s Vineyard with his life partner, Bridget Dunnigan, MS, DVM, who is also an aquatically trained veterinarian. They live with their three dogs, two cats, and five birds where they enjoy hiking, kayaking, and international travel to explore the world’s avifauna. They own and operate the Vineyard Veterinary Clinic in Edgartown.  Currently employed by the National Marine Life Center, Dr. Williams started his aquatic training during vet school at the University of Pennsylvania by attending AquaVet® and AquaMed® courses and participating in the Aquatics club. After a few years in companion animal and mixed animal practice Dr. Williams added more formal training, completing a clinical internship at the National Aquarium in Baltimore. Upon moving to the Vineyard he realized that there was no on-island veterinary stranding program. Roger and Bridget have been the primary responders to over a hundred marine mammal and sea turtle strandings as volunteer veterinarians working under the Stranding Agreement of the New England Aquarium. In 2002 they accepted a split position as veterinary medical officers for NOAA Fisheries and as the veterinarians for the Woods Hole Science Aquarium. They responded as government veterinarians to strandings, marine animal transports, and provided the veterinary care for the aquarium’s collection of seals, fish, and invertebrates. They helped re-establish a sea turtle rehabilitation program at the aquarium in coordination with the New England Aquarium. In 2007 they left the aquarium and Dr. Williams accepted the position of director of science, and in 2008 as the attending clinical veterinarian, for the National Marine Life Center. Dr. Williams has a long established interest in infectious disease, particularly parasitic interactions, occurrence, and disease. Dr. Williams has published scientific articles in the fields of fish ophthalmology, marine mammal hematology, sea turtle pathology, infectious disease, and parasitology.
