Meet the Doctors

  • Dr.
    Keith Parendo

    Born and raised in Mineola, Dr. Parendo began his veterinary journey in high school when he started serving as a kennel attendant and veterinary assistant at a local clinic. After majoring in pre-med and economics at the University of Notre Dame, he began his veterinary schooling at Murdoch University in Perth, Australia. A year and a half later, Dr. Parendo transferred to Ross University after meeting his wife. Upon completion of a clinical year at Purdue University, Dr. Parendo returned to Long Island and began practicing in Nassau County. He spent nearly 8 years working as an Associate Veterinarian there, then split his time between two Suffolk County animal clinics before fulfilling his long-standing dream of practice ownership when he bought St. Francis Hospital for Animals in the spring of 2014. Medically, Dr. Parendo enjoys dental work, oral surgery, and tumor removals because of the instant positive results he can provide for a pet. He’s also fond of puppy and kitten visits; being able to start young pets and their new owners off on the right path is very gratifying for him! When Dr. Parendo is not at the office, he can be found fishing, playing or coaching lacrosse, golfing, and spending time with his wife, children, and dogs “Lax” and “Libby” in Babylon, New York.
