Dr. Sullivan grew up in the coastal New England town of New London, CT.  He earned a Bachelor of Science degree from the University of Connecticut in 1976.  Upon graduation, he gave in to his newly found spirit of exploration and spent the next four years traveling between Latin America, Spain, and the U.S.  During this stint, he enrolled in the College of Veterinary Medicine at the Universidad de Cordoba in Cordoba, Spain.  Although the experiences in Europe were enriching and memorable, in 1980, Dr. Sullivan decided his educational pursuits might better be realized back home.  He returned to the States and shortly thereafter enrolled in the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech in Blacksburg, VA.  In 1985, he earned his veterinary degree.
Dr. Sullivan Began his career at Squire Veterinary Clinic in Upper Marlboro, MD where he met his future wife, Eileen Garvey.  This was a mixed animal practice where he split his time taking care of farm animals as well as dogs and cats.  After a short stint at Bay Country Animal Hospital in Crownsville, MD, Dr. Sullivan accepted the position of Medical Director and Veterinarian, where he oversaw the opening of the Animal Emergency Center in Timonium, MD.  He spent six years there practicing emergency medicine and critical care, and directed the early years of the Center which has now evolved into the well-known PetER in Towson, MD.  Dr. Sullivan left emergency medicine for the Ellicott City Veterinary Clinic which he purchased in 1994.  In 2002, the Ellicott City facility was moved to its current location as the West Friendship Animal Hospital.  In the same year, he helped organize the group of doctors which opened the cooperative after hours emergency veterinary facility in Ellicott City known as the Emergency Animal Hospital.  Today he continues to function as its Hospital Director and serves on the Board.
The Sullivan family has grown over the years.  Eileen has her Master's Degree in Critical Care Nursing.  She currently works full-time as a mom and works part-time in a coumadin laboratory in Columbia, MD.  The children include Patrick Bryan and Casey. Patrick is enrolled at La Salle University in Philadelphia and is a member of the soccer team.  Bryan is enrolled at Howard Community College and their daughter Casey attends Mount View Middle School.  There is never a shortage of pets in the household.  Last count, Monty the cat was outside discussing hunting rights with the fox, Freddie the bichon-poo was sleeping on the couch, and Roscoe the beagle was watching Monty through the picture window.  Oh yeah, and Bubbles the goldfish is hoping they don't forget to feed him.
