Oonagh Wack

Dr. Oonagh Wack enjoys surgery, ophthalmology cases, pocket pets, and the ability to have long term collaborative relationships with clients and their pets to make the lives of pets’ and their people better.

Dr. Wack grew up in Canada and earned her Bachelors of Science from St. Francis Xavier in Nova Scotia and her veterinary doctorate from Atlantic Veterinary College on Prince Edward Island. She furthered her veterinary education as an intern in small animal medicine and surgery at the Western College of Veterinary Medicine in Saskatoon. The Maine lifestyle and the opportunities afforded in our state are what drew her back to Maine. She joined Falmouth Veterinary Hospital in 2005.

Dr Wack is married to John Keating, a veterinary pathologist working within the medical device industry. He is also a former Tufts Veterinary School professor. Drs. Wack and Keating have an extensive family including five dogs, three cats, four tanks of fish, and various finches. The pets have a medley of creative names including Jimmy Page, Ronny Wood, Lemmy, and Joe Strummer, amongst others. In her free time, she loves quilting, gardening, kayaking, traveling, and hiking with her dogs.

Read What Our Clients Say

  • "My two cats consistently get the BEST care from the vets at Falmouth Veterinary Hospital, starting with the lovely people at check-in to the kind and caring folks upon leaving. The vets and assistants genuinely care about the health and well-being of our two kitties, and as a pet mom, I always feel reassured and happy with their care."

  • "I have been a client there for over 30 years. Care is always excellent. Would not want to ever have to go elsewhere. They are great and so loving when treating my dogs."
    Marcia M.
  • "Dr Graves goes above and beyond with our senior dog. He is caring and thoughtful and respectful. He understands that our dog is a part of our family and treats him as such. The other vets we have met have been just as great and all of the staff are friendly and helpful. We could go to closer practices, but we won’t because this crew is worth the drive."
