Read What Our Clients Say

  • "After leaving a vet I was not happy with, I did extensive research before I settled with another. Guardian Pet seemed like far and away the best choice given my research, and time has shown I was right. They truly exist to help your loved one. Their knowledge, empathy, and dedication make them what they are. I have referred several friends and coworkers to Guardian Pet, all who have found the same satisfaction that I have."
    Aislinn M.
  • "I have been taking my Beasties to Dr. Joy for at least 10+ years. Dr. Joy and her staff know all the animals, and really care. I never worry when I have to leave my pets. She takes the time to answer all questions, and will go over them until you are comfortable. She gives you options. Unless there is an emergency, I wont take my animals anywhere else.
    Thank You,
    Shawna, Borris, Natasha, Dinaha, Amber, and Mouse"
    Kandi C.
  • "Dr. Joy and her staff are fabulous. It is wonderful to have such comfortable relationship with the doctor who cares for your four-legged family members. Doctor Joy has been there for me during some really tough times and I trust her advice implicitly. I can honestly say this veterinary practice is the best I have encountered in over 40 years of pet ownership."
