  • "Good facility easy parking, modern building. The Vets, vet techs and support staff are caring and compassionate and take the time to explain everything. While waiting to see the vet I have seen a wide variety of pets come through the reception area. I have taken my dogs here and to their old location for the last 20 years despite moving away from this practice."
    Claire G.

    Ed S.
  • "Palomar Animal Hospital is a great place to take your animals. Dr. Handel and crew are the best. I've been bringing my dog here for four years and they are wonderful. Dr. Handel saved my brother's dog in an emergency. He was calm and literally brought him back from the brink. You can't go wrong with PAH. Great atmosphere and everyone has your pet's care as their number one priority."
    Michael N.
  • "My husband and I moved here four years ago with two 12-year-old dogs. As our
    girls reached the ends of their lives, Dr. Handel and his staff showed great
    compassion and understanding. During the process it became clear there was
    nothing that could be done. He let us know what to expect and made them both
    as comfortable as possible. He then transitioned from caring for our girls
    to taking care of us. His compassion for his animal and human patients goes
    beyond anything we have experienced previously. We highly recommend Dr. Handel and Palomar Animal Hospital."
    Patricia Collins
  • "Dr Handel and the staff at Palomar Animal Hospital are the very best in vet
    care. We have been taking our dogs to both Dr Handel and Dr Knox since 2005
    and they always take the time to expertly diagnose and treat our dogs in a
    compassionate and caring way. We have come to fully rely on their clinical
    expertise through difficult cases such as cancer, orthopedic surgery and
    diabetes and they bring in great specialists when needed. The receptionist
    staff is always friendly and helpful and the vet techs are wonderful. We
    highly recommend Palomar Animal Hospital for all of your vet needs."

She thought back to her love of animals, and realized veterinary medicine was the perfect way to combine her scientific interests with her passion for helping others!
