My Guinea Pig Bear had a tumor and they have worked hard to care for him and follow up to be sure he is healing well from surgery removal as well as be available to answer any questions I have.I was even able to set up an affordable payment plan for his medical bills. All in all a very trustworthy Vet Clinic."
