Read What Our Clients Say

  • "We have been going to Brandner Vets for around 12 years and they are the absolute best from the front staff, dr’s, and support team. We have had two dogs under their care for this time with never a problem or concern with the quality of service. We have a 25 year history with vets and Brandner is number 1 in our book. Thank you"
    Richard Stefani
  • "Dr. Pfann was exceptionally kind and considerate when we brought my daughter's mouse in for a respiratory infection. He is a pet lover himself and his interest and compassion was evident. His fees were very reasonable. Pets have a special place in our hearts and this hospital seems to recognize that connection we all have with our animals, even the smallest and most vulnerable. We thank the staff for all their help. We wish we had known about Dr. Pfann and his staff sooner!"
    Andrea S.
  • "We've been with Brandner Veterinary Hospital for close to 20 years because of the many "Parental" considerations that inform the love and care of our beloved pet family. Brandner has provided our dog Emma and our kitties Pippi, Orca, Buster, and Mushu the finest and most knowledgeable care that gives us the comfort and reassurance that abides our total commitment to our 'kids'."
