1. Dr. Diane Cosko and her talented staff have been caring for our pets for decades. They go the extra mile every time. Very thorough and knowledgeable.

  2. Mountain Aire Veterinary Hospital has been caring for my animals since I moved to Frazier Park in 2001. They are so good that I don’t think I can ever move off this mountain. They leave no stone unturned to get your pet the best care possible. Their customer service is top-notch. I do not find them to be overpriced for the care that your pet is getting. I come from Los Angeles. The quality of care at Mountain Aire exceeds the quality of care that I have received from very pricey vet hospitals in Los Angeles. I love the communication that Dr. C. has with her customers. It’s so good that I become annoyed when I have to use an Emergency vet when they are closed. If you truly want the best care for your pet there is no better Vet hospital. I wish Dr. C. treated people. I really do. Every doctor should be as committed to their patients as Dr. C is. I completely trust her and if she says something needs to be done, you can rest assured it’s in the best interest of your pet. I’m grateful for their attention to detail. The vet techs are expertly trained and everybody there has become family to me. Thank you for bringing an excellent standard of care to this mountain!

  3. I always enjoy going to Mountain Aire Vet with Jake. First he gets weighed as soon as he walks into the door. Greeted by the friendly and helpful staff, Jake feels right at home. Not a long wait, and Jake is off to the exam room for his physical and boosters. The place is always clean and the staff is very friendly. We would recommend this facility to anyone who loves their pet like one of the family

  4. Our family has been a client of Mountain Aire for almost 20 yrs. Dr. Cosko is an excellent veterinarian and I appreciate the care she and her friendly staff have given all of our animals during this time. We are blessed to have access to such a fantastic veterinary hospital here in our mountain communities!

  5. My pet is well cared for and we felt the love for our little dog. We appreciate all of the staff. We are on the mountain part-time and it certainly feels great to have a veterinarian while we are there.

  6. Has been my vet for over 20 years. The team and Dr. Cosko are caring and kind. I have since moved away from Frazier Park but Dr. Cosko and Mountain Aire are still my vet.

  7. The care we receive at Mountain Aire is excellent. Our questions and concerns are always answered promptly. Any time we have brought our pets in they have been provided with knowledgeable and professional care.The staff is great. The receptionists are friendly and welcoming. The Vet Techs treat all the pets with tender loving care and do a great job with patient education. Dr. Cosko’s skill and knowledge combined with her concern for my pet's comfort and health adds to the overall feeling of competence when you bring your pet in for any problem. I would not take my pets anywhere else for care. I know that the staff at Mountain Aire care as much about our pets as we do.

  8. Everyone at the clinic were kind and empathetic of my beloved dog’s distress as well as my worries about her. I felt that my dog’s health and well-being were a priority for them and I felt very comfortable leaving her there for a few hours.

  9. Yesterday I brought our sweet Alex (cat) into Mountain Aire Veterinary after discovering he got hit by a car or in a bad fight. They took him in right away! Everyone in the office was very friendly and professional. I had to leave little Alex at the client for observation all day but I knew he was in safe hands. Dr. Cosko was very thorough and cares about her patients. Thank you, Mountain Aire!!! Alex is doing better today because of your services!!!

  10. I have never been so impressed with a veterinarian and her staff before. The Mountain Aire staff are truly caring people. They went out of their way to make sure Basil (my sweet dog) was getting the best treatment possible and also, with great patience, explained to me the things I did not understand. My only disappointment is that they do not take humans as patients – If only I could find such a thorough doctor for myself!

  11. One of the reasons I bring my dogs to Mountain Aire is because of the doctor and her staff. They genuinely care about your pet and both our dogs get excited to come to visit. The care given to our dogs is top notch and Dr. Cosko is very knowledgeable and thorough. Be prepared for your visit to take a while.. Prices are high, but I’m willing to pay a little more for the excellent care.

  14. Dr. Cosko and her ENTIRE staff are the best! Gibbs & Taos love going there. When I pull into the parking lot they can’t get out of the car fast enough. You will never find a better place for the care of your pet!

  15. Wow! They all are the very best. The whole staff have been there for us every step of the way for nearly 20 years. Love and thanks to Mountain Aire Veterinary Hospital
