Margaret Valentino, DVM MPH CVA CVFT

Margaret Valentino DVM

Dr. Valentino was born and raised on Long Island. She graduated Cum Laude from the University of Delaware with a bachelors degree in animal science, pre-vet concentration. During college, Dr. Valentino joined the US Army Reserves as a Civil Affairs Specialist and was deployed to Iraq and Kuwait for just over six months in support of Operation Iraqi Freedom/Enduring Freedom. While in the desert, she completed her application interviews to vet school via satellite phone, and began her veterinary education at the University of Minnesota soon after being released from active duty service. Having an interest in public health, and particularly infectious disease and population medicine, Dr. Valentino worked concurrently on a masters degree in public health while in veterinary school, completing it one year after she earned her Doctorate of Veterinary Medicine at the University of Minnesota in 2007. Having accepted the Health Professions Scholarship from the US Army to help pay for veterinary school, Dr. Valentino started her active duty service obligation as a military veterinarian at Fort McPherson, in Atlanta, Georgia, in 2008. Between graduating from veterinary school and starting as a Veterinary Corps Captain, Dr. Valentino completed a year-long internship at Long Island Veterinary Specialists where she developed a passion for high quality medicine. Having met her husband in Georgia during her time at Fort McPherson, Dr. Valentino stayed in the Atlanta area, working at a variety of small animal clinics, balancing life with two small children. Looking for more options to help aging patients, she became interested in Traditional Chinese Veterinary Medicine as a way to help heal and bring better quality of life, particularly when western medicines do not seem quite enough. She finished her course work for a Certification in Veterinary Acupuncture in 2018 at the Chi Institute in Florida, and is constantly continuing to advance her understanding of Traditional Chinese Veterinary Medicine to be able to help more animals live happier, healthier lives for longer. She moved back to Long Island a few years ago to be closer to her parents, and is looking forward to continue practicing veterinary medicine with a holistic approach that uses the best of both eastern and western medicine. In her spare time, Dr. Valentino enjoys taking day trips with her kids, especially to the beach, and walking their dog Max around the neighborhood. Aside from Mr. Max, Dr. Valentino shares life with her parents’ dog Maggie, sister’s dog Holly, two guinea pigs, and about two little fish.
