Mountain Aire Veterinary Hospital

Mountain Aire Veterinary Hospital has been an Accredited Member of the American Animal Hospital Association from 1989-2014. As of November 2014 we are no longer seeking membership as an AAHA accredited hospital. The new AAHA policy regarding dentals would force us to anesthetize patients we feel should not go under anesthesia for an elective procedure. Since 2004, we had proudly and repeatedly ear

ned recognition as a THREE YEAR MEMBER, which is the highest honor a veterinary hospital can receive. What this meant was that MAVH exceeded the AAHA standards to such a degree that we were not required to have another inspection until each three year period expired. Regardless of our AAHA accreditation standing, we will continue to improve and raise our standards in order to maintain such an accomplishment and provide our clients and their pets with the highest quality of care available. If AAHA chooses to change their policy at a future date we may reconsider our membership application status.

Jordan is a new face becoming more and more familiar around the hospital as one of our veterinary technician assistants. Here she is with Batman helping soak his feet in a warm water bath of betadine, epsom salts and baking soda to alleviate the pain and swelling from foxtails (and we ALL look forward to such a nice foot soak at the end of a long day).

Foxtails are the wooooorst! They get stuck in all the nooks and crannies.

This is Goose. She is a very lucky dog to have been adopted by Holly. Holly may not feel so lucky as Goose almost immediately developed an almost fatal disease where she became allergic to her own red blood cells (immune- mediated hemolytic anemia). Thank goodness Holly had the foresight to get an insurance policy as soon as Goose was adopted, which helps to pay for the tremendous costs of specialty care, blood transfusions and follow-up care. But it doesn’t make up for the time and stress that Holly has gone through. Goose is even luckier to have such a thoughtful and caring mom as she is well on her way to recovery.

Cat's dog Vera took up her post once again as Office Manager after visiting for a routine service. Biannual services are very important for senior pets as it assures monitoring of existing issues and catches any small changes before they become bigger problems. Staff moral was kept up with plenty of tail wags and smoochie boochies.... as well as a persistent nudge to "keep working" in a timely manner. Also known as delivering belly rubs on time during her naps under the reception desk.

Our Story

Dr. Diane Cosko received her first college degree (Bachelor of Science) at the age of 19 and went on to earn a second bachelor’s and then her DVM degree by the age of 24. Driving all the way up from her veterinary jobs in San Diego and then West Los Angeles on her days off, Dr. Cosko made herself available to help the residents of Frazier Park procure some veterinary care for their pets while their regular veterinarian was indisposed. After events created an opportunity for Dr. Cosko to start her own veterinary business, she started out small, with just $1800 to her name. Always promoting lifelong education with all of her staff as well as herself, Dr. Cosko has also become an attorney-at-law in 2010 specializing in animal law and has just received her Masters in Veterinary Sciences - Forensics in 2019.

Mountain Aire Veterinary Hospital actually started out as Mountain Aire Veterinary Clinic in a small motor home borrowed from her parents and parked in their cabin’s driveway along the dirt trail behind the rock houses. Within a year, it moved to the ‘spacious’ 600 square foot facility next to the current Hall Ambulance in downtown Frazier Park. So spacious were these facilities, Dr. Cosko remembers fondly, that her ‘office desk’ was comprised of her sitting on the only ‘chair’ in the building (the toilet), holding a cutting board on her lap!

Here is where she forged many long-term relationships with clients that still utilize the current hospital 29 years later!!! Along with their now-grown children coming in with their own pets. Also, here is where Dr. Cosko created her initial relationships with clients that subsequently became employees and are still working with her today.

Without the exceptional and hard, tireless work of Dr. Cosko’s co-workers, she would not be able to deliver the excellent care that people have come to expect to this day.
