This place is truly phenomenal. I wish I lived close enough to take all 7 of my cats for their regular care. I traveled 2 hours away to see Dr. Werden for her opinion on the status of my cats FIP treatment/recovery and a host of other issues (eye discharge, asthma, kidney stone). She and her staff were so friendly, thoughtful, thorough, and smart. I learned more from them in this one visit than in 15 years of cat ownership, visiting other veterinarians. The post-visit write-up and communication was thorough, organized, and encouraging in that I felt truly heard. I cant say enough good things

I cant say enough good things about dr. Warden and her staff. They saved my cats life! My cat was seriously sick. Both the vet I usually see and a specialist said they could do nothing to save him. Then a friend recommended Dr. Warden. Harmony Hill is over an hour from my house. When I got there, it was 10 minutes before closing time and it was Christmas eve. But they took me in anyway and spent an hour and half evaluating and treating my cat, and coaching me on home care. 3 days later, my cat started to improve. The office staff are always courteous and efficient. After checkout, they would
