Dr. Mark Sibley, DVM

Dr. Mark Sibley

Dr. Sibley was born and raised here on Long Island. He attended Cornell University to complete his undergraduate education and then stayed there to study at Cornell’s College of Veterinary Medicine. As a young graduate, Dr. Sibley is motivated to continue learning as much as he can from his talented colleagues.

He enjoys the challenge of practicing medicine, but his passion comes from helping animals to live the longest, healthiest lives possible alongside their human companions. Dr. Sibley has particular interests in radiology, dermatology, and general wellness/preventative medicine.

Outside the clinic, Dr. Sibley spends much of his time spoiling his own animals: Nami (an energetic Corgi) and Sangha (a charming senior cat).
