Read What Our Clients Say

  • "Been taking my pets to Dr. Phillips for years - I highly recommend him. His approach reminds me of my personal physician - he keeps you informed at every step as he logically and methodically diagnoses pet issues. His medical knowledge has never let us down and his "bedside manner" has kept my pets (and their owner) calm and confident through even serious medical issues. I wouldn't take my pets to anyone else."
    Bill W.
  • "When your furbaby needs to be taken care of, this is the place to go."
    Jason P.
  • "Dr Phillips has been our vet for years and is so smart! He is caring and really down to earth. We have had several dogs with health problems over the years and he worked with us to find treatments that were realistic for our family."
