  • "We want to thank Dr. Derfuss and her entire staff at Branchburg Animal Hospital for all of the wonderful service and care we have received over the years. We've been with the practice since it opened many years ago. Whether we are coming to the office to pick up food or bring our pets in to be treated, we are given the best care. They are like family to us. We give them an A++ and have recommended them on many occasions."
    The Del Grosso Family
  • "Linda and I have been bringing our Labrador Retrievers (first Shiloh and now Cooper) to Dr. Derfuss and the Branchburg Animal Hospital for many years. We have always admired and embraced the leading edge, holistic healing practices that are employed there. This has included such applications as acupuncture, chiropractic and the utilization of natural supplements, all of which have appreciably augmented the overall quality of life for our beloved canines. At a time and in a country where the overuse of prescription medication has clearly run amok, it is great to have a facility in our area where numerous other alternatives are deployed and RX medication is applied on a far more discerning basis."
    Kevin B.
  • "My husband and I have been taking our German Shepherds to Dr. Derfuss for many years. She is extremely caring and compassionate. She not only practices traditional medicine but holistic too. Our "girls" actually loved when they went to the vet! We highly recommend Branchburg Animal Hospital!"
    Carla B.
  • "I’ve been bringing my cats here for 15 years and Dr. Derfuss and the staff have been caring and compassionate. Holistic treatments are available if you want them, depending on the animal’s condition, and I have gone this route a couple of times for ailing cats. I never felt pressured into accepting any particular treatment. I’ve always been given all the options and chose what I felt was best. There are a number of vets closer to where I live, but I continue to make a slightly longer drive to Branchburg Animal Hospital because I trust them."
    Loretta A.
  • "Great Vet, Professional Staff, Very Clean. We are fortunate to live close to this great Vet!!"
  • "For the past five years, the veterinarians at Branchburg Animal Hospital have taken great care of Stitch. I highly recommend this vet for your cat or dog."
