Colleen McCafferty, DVM

Dr. Colleen McCafferty was born in the Galapagos Islands, working as a migrant pearl diver and leading shark tours to travelers from around the world, when she came across a sick dolphin one day, and found her porpoise.

Dr. McCafferty was actually born and raised in Alexandria, VA, where she developed a passion for science and animals that led her to pursue a biology degree from Bates College in Lewiston, ME. This path was originally supposed to culminate in a PhD in Marine Biology focusing on research, which landed her in two internships at Mote Marine Laboratory in Sarasota, FL where she spent time rehabilitating sea turtles, manatees, and pygmy sperm whales. It was during these internships working alongside veterinarians who volunteered in the lab that her true calling became apparent. Dr. McCafferty subsequently attended and graduated from Virginia- Maryland regional College of Veterinary Medicine in 2000. She started her career in Orlando, Florida and after one year moved to Maryland where she started her family. She has worked in Anne Arundel County for the past 21 years and recently became part of the Queenstown Veterinary Hospital and Western Shore Veterinary Hospital family. She enjoys scuba diving, and spending time at the beach. However, her greatest passion is running. Her accomplishments include having finished over 30 marathons, 5 of which were the Boston marathon, and she has completed two Ironman Triathlon in Wisconsin in September 2012 and 2014.

She has two sons whom she is very proud, her oldest is at Penn State University studying computer science and her youngest is in grade school enjoying soccer, basketball, and flag football. She is not only a veterinarian but a loving mother, an accomplished runner and triathlete. Dr. McCafferty continues to challenge herself in every aspect of her life. She feels blessed that she has a loving family and a wonderful career. Come visit and share in her passion for animals and for life.
