Lisa D. Mandelin, DVM

Laguna Niguel Veterinarian Lisa MandelinDr. Mandelin was born in Seattle, Washington and raised in sunny Southern California. She graduated high school from the Bishop’s Schools of La Jolla, California, and soon thereafter made her way to Fairbanks, Alaska where she attended the University of Alaska on an athletic scholarship in volleyball. She spent several years living the Alaska lifestyle before heading south to ‘thaw out’ in sunny Clearwater, Florida.

Prior to her career in veterinary medicine, Dr. Mandelin pursued a career in the human medical field. She studied orthopedic and emergency medicine while serving as a medic in the US Army. After her military service she became the lead orthopedic technician for a busy orthopedic surgery department in Denver, Colorado and also worked in emergency rooms and nursing homes in Denver and Fort Collins, Colorado. It was during these years of working in the human medical field that Dr. Mandelin was introduced to veterinary medicine. Her goal of going to medical school to become an MD soon evolved into the goal of going to veterinary school…..and she has never regretted that decision!

After graduation from Veterinary College at Colorado State University in 1998, Dr. M. practiced briefly in San Diego before accepting a position as the medical director of a small clinic near Palm Springs, California. Two years later, she would go on to purchase her own practice. After successfully building that practice, she sold and became a private contractor of veterinary medical services for numerous clinics throughout California and Florida. Dr. Mandelin’s experience in the human medical field has allowed her to create a unique and much-desired blend of high quality veterinary medicine.

Her special interests include Emergency Medicine, Soft Tissue Surgery, General Wellness and Chinese Acupuncture. In her spare time she enjoys running half marathons (her goal is to run one in each of the 50 states), sailing, kayaking, bicycling and loving on her four kitties….Mina, Fu Manchu, Levon and D’Accord, and her Australian Shepherd dog Shiloh.
