Meet Paumanok Veterinary Hospital’s Outstanding Veterinarians

Dr. David Hensen and Dr. Deirdre Hensen are the husband and wife proprietors of Paumanok Veterinary Hospital and between them have over 50 years of experience caring for pets. Their core beliefs, nurtured from strong family and ethical backgrounds, are front and center in their approach to veterinary care. We are excited to have you to meet them and their associates too.

The Hensens have four dogs (three at home and one handicapped dog at the hospital), two cats, three horses, 14 chickens that produce Paumanok organic eggs, one rabbit, one guinea pig, and one cockatoo. They understand the human-animal bond and the attachment you have to your pet.


David R. Hensen

Dr. David R. Hensen

Dr. Dave graduated from veterinary school in the Dominican Republic in 1982, where he learned to speak Spanish fluently. He has a keen interest in diagnostic ultrasound. In 1988, he became a Diplomat of the American Board of Veterinary Practitioners, a prestigious honor that recognizes him as a specialist in the practice of companion animal veterinary medicine. Look around — there are very few veterinarians who can make this claim. 

He is a member of the Long Island Veterinary Medical Association (LIVMA), New York State Veterinary Medical Society (NYSVMS), American Veterinary Medical Association (AVMA), the American Veterinary Ultrasound Society, and many community and conservation organizations. Before opening Paumanok Veterinary Hospital, Dr. Dave worked at Aldrich Animal Hospital, Miller Place Animal Hospital, Animal Emergency Hospital, and Smithtown Village Animal Hospital.
