Meet the Staff

Meet the friendly staff at Peninsula Animal Hospital!

  • Dr.
    Aaron Cohen

    A native of Jacksonville Florida, Dr. Aaron Cohen’s first pet was a baby chick by the name of “Peep-Peep”, who eventually grew up to be a rooster. After that, he pretty much stuck to just cats and dogs.

    Dr. Cohen attended the University of Florida, Gainesville where he studied animal science and psychology. Shortly thereafter, he transferred to Northeastern University in Boston. He completed his Doctor of Veterinary Medicine at Ross University, St. Kitts in the West Indies.

    After serving in an internship program at the Massachusetts Society for Prevention of Cruelty to Animals in Springfield, Mass, Dr. Cohen settled in with Porter Square Veterinarians of Somerville for the next seven years. Deciding to start his own practice, Dr. Cohen began an exhaustive search that would bring him from the East Coast to the West Coast.

    Dr. Cohen bought Peninsula Animal Hospital in December of 2010. He is active in the American Veterinary Medical Association, California Veterinary Medical Association, and the Monterey Bay Veterinary Medical Association. In his free time, he enjoys hiking, biking and conversing with his cats.
