After college, Dr. Hess moved to Prince Edward Island, Canada to attend veterinary school at the Atlantic Veterinary College. She is a recent graduate from the class of 2017, and has returned to her roots to join us here at Assisi. Dr. Hess is excited to begin her career as a veterinarian and has a special interest in feline medicine. Some of her favorite things include spending time with family, cooking, and enjoying the fall season. She lives with her partner, who is also a veterinarian, their four cats (Goose, Uggs, Bambi, Gracie), and their miniature lop rabbit named Theodore.

I highly recommend Assisi Veterinary Hospital!  I've known Dr. Guzman over 4 years. He s always been professional and willing to answer all kind of questions. 

Dr. Ricarlos Guzman is the founder and owner of Assisi Veterinary Hospital. Born in Brooklyn and raised in Queens, Dr. Guzman is proud to establish a hospital serving Long Island and our neighboring boroughs. After graduating from Florida Southern College and completing his prerequisites at the University of Florida, he continued his education at Tuskegee University School of Veterinary Medicine. While completing his degree, Dr. Guzman participated in multiple externships including one at The Animal Medical Center in New York City. After his graduation from Tuskegee University, Dr. Guzman participated in a fourteen-month internship at the West Palm Beach Veterinary Referral Service. This internship was focused on surgery, internal and emergency medicine. Dr. Guzman also worked as a general practitioner in Long Beach, New York prior to founding Assisi in 2007. Also in 2007, Dr. Guzman received accreditation from the United States Department of Agriculture to perform services in connection with interstate and international animal travel. In addition to being a Veterinarian, Dr. Guzman enjoys spending time with his wife, whom he met in Veterinary School and is also a Veterinarian.
