Facility nice and clean, nice staff BUT to take our pets for vaccines and get ripped off with a $400 bill and no vaccines yet just bc the Doc. said this is not a vaccine clinic and performed a titer test first? hmmm indeed she does her own practice. Not sure if will be back, our pets gotta wait for 7 days for blood result test and without vaccination! how is that! hug! Lol amazing! We think she does what she does bc she knows is the only one in FP. Too bad, I wish others vets move on to the town.

My Breeder for my new Puppy was using this Vet Service. I attended 2 puppy appointments and have been impressed with their professional services and home doctor atmosphere. It it was not an hour drive to the vet I would use their services regularly.

This is an amazing place. The vet is so wonderful, caring, and skilled. Her employees are amazing too! I live in Bakersfield and I would rather drive here to Lebec than go anywhere else! And Rosie (my dog) loves this place too!

Dr. Cosko and her staff are the best. They are caring and very professional. I know that all our pets are in good hands when we visit. Early diagnosis and care goes a long way to having long living healthy pets. Thanks!

I like this place. All are very friendly. They made my Harley feel comfortable which made me feel at ease as well. Staff is very knowledgeable. They take great care of puppies to prevent them from having any major health issues as seniors.

VERY knowledgeable and friendly staff, who know how to handle as well as interact with animals. Very accommodating, they'll do whatever it takes to make sure the job gets done, even taking your pet's blood sample down to the CHP office so that they can use the centrifuge when they lose power! If I could give six or even ten stars, I would.

As a result of Dr. Cosko's recommended treatment, we have noticed some very positive changes! Frankie no longer flinches when touched; she happily bounds around, wagging her whole body. She has a smiley face very frequently, and is the most comfortable and happy that she has ever been since we adopted her. She is a different dog, and Dr. Cosko's recognition of Frankie's emotional struggles has resulted in a focused treatment in that area, which has yielded a far more healthy and happy dog than if only her physical problems had been treated. Dr. Cosko's understanding and use of a combination of conventional medications, coupled with the proper, focused probiotics, has made the biggest difference in the quality of Frankie's life, so far.

I love my dogs, and seeing results like this in both Molly's and Frankie's lives, has taught me a new concept of value delivered for the monetary expenditure paid. In this area, Mountain Aire Veterinary Hospital delivers more value for my hard-earned money than any other vet I've brought my dogs to, ever. I recommend Dr. Cosko and her staff!

This place is infamous for sky high prices and unnecessary testing. They have ripped off yet another acquaintance of mine charging $500 for a yearly checkup. I've never heard anything bad about the quality of care but they consistently take advantage of people who just want the best care for their pets.
