Born and raised in Southern California, I couldn’t ask for a better place to live than the Greater Frazier Mountain Area. Each day I look forward to coming into work. Veterinary medicine is my passion. I feel so very lucky to be doing what I do in such a beautiful environment.
Over time, many, many years ago, I received 3 degrees from UC Davis. A Bachelor in Science degree for Behavioral Genetics, another Bachelor in Science degree for Veterinary Science and, in 1987, a Doctor of Veterinary Medicine degree. After spending a large amount of time dealing with animal law, I finally did get a law degree and passed the California State Bar in 2010 so I can now do even more as far as different aspects of animal law are concerned.
Currently, I am getting a Master’s degree in Veterinary Forensics to bridge what I do with law and medicine. It’s as exciting as one would envision from all of the television programs but not so much hoopla! I have been working as a veterinarian in the Frazier Park area since 1988. Out of necessity for the community, I started Mountain Aire Veterinary Hospital in July of 1989. I have lived in Pine Mountain Club, Frazier Park and now Lebec, with my husband, Bob Leonis (bass player for the local cover band, “Driver”) and always enjoy a house full of “4-legged” children.
Although my hobbies are many, my free time to enjoy them is scant. But I especially enjoy the arts (sculpture, drawing and tile-painting) and traveling (if anyone knows me, they know my favorite place to visit is Tasmania!) Unfortunately, most of my free time is spent weeding out those horrific plants called ‘Foxtails’ that can and do harm the animals.
Prior to moving up here full time in 1990, I worked in San Diego and West Los Angeles – for all of their conveniences and diversity, I would hate to have to move back – it’s just too beautiful up here. Many of my clients that I have known since the late eighties and early nineties are still bringing their pets to me today, as are their now-grown children, who are now adults and have their own children! – it makes for one very large, extended family.
Hi, my name is Tami. I initially started as a client back in 1991 and was impressed with how friendly everyone was and how they cared for my pet. I eventually asked if I could volunteer, which turned into my applying, going to school and becoming a certified Vet Tech. I am a big animal lover and I have always had them since I was a little girl. Taking care of animals has always come natural to me, and my coworkers say I even talk their language. That is why I went back to school and became a Certified Dog Trainer, as well.
I currently live in Cuddy Valley with my husband Patrick (of Shanpat Construction) 2 dogs Chloe and Nala, one cat Cookie and PJ my bunny. Talk about Pet Insurance! I’m hoping to have horses someday also.
Here at Mountain Aire I assist with surgeries, x-rays, lab work, and restraints. Sometimes you’ll even see me doing reception. No matter what I’m doing, I will be treating your pet with a lot of TLC to help their experience here be as pleasant as possible.
Hi! My name is Sandy and I have been working at Mountain Aire since 1999. I have pretty much lived here on “the hill” my entire life and at this time have no plans to leave. My husband Mike and I have 4 kids, 4 dogs and 2 cats – never a dull moment!
I really enjoy my job and am proud to tell people I work at Mountain Aire Veterinary Hospital because of the high standard of care we provide your pet.
Well hello there! My name is Cat and I am the Director of Kennels and a Technician Assistant at Mountain Aire’s very own, exclusive pet resort; “Camp Cosko.” It’s my duty to assure your “kids” are properly cared for (and spoiled rotten, I might add) while you take care of both business and pleasure out of town. I also work as the animal world’s version of “back-up singer.” I lend a hand around the hospital wherever needed by the technicians, receptionists, or… well…. anyone hollering loud enough, as well as assure the facility is well-maintained, stocked and up to our sky-high standards. Ultimately, I spend my work day playing with cats and dogs. Who could complain?
I started out with Dr. Cosko my senior year at Bakersfield High School way too long ago. After earning Bachelor degrees from both Scripps Womens College (’00) and the Art Institute of Pittsburgh (’03), plus short careers as a zoo keeper, animal and horse trainer, I find I can’t stay away from the Mountain Communities and moved back to the hill in 2002. Ever the perpetual student – it’s Dr. Cosko’s fault – in 2012 I completed coursework for becoming a CA State Licensed Veterinary Technician.
Hi my name is Sarah. I’ve always had a special connection with animals, and found myself involved in the veterinary field from an early age. Like most in this field, I started out cleaning kennels, and worked my way up to senior veterinary assistant over the last 19 years. My areas of interest include dentistry, nutrition, and practice management.
When I’m not evaluating a pet’s dental status, or working clients on their pet’s diet, and caloric requirements, or maintaining the hospital inventory, I can be found at home with my kids. Besides the fur-less children, I have 2 dogs- Sam and Tucker, and 1 cat named Joey. I also enjoy scrap booking, cooking and spending time camping with my crew.
Pursing her innate passion for nature and animals, De Ann earned her degree in Animal Training and Management in 1991. Over the past 25 years she has cared for over 200 species, trained animals around the world for various film productions and taught in-home obedience as well as collaborated in the development of group classes; teaching as many as 13 classes per week! De Ann also enjoys horseback riding, hiking, camping and volunteering for pet and wildlife rescue.
Robina is a full-time animal person. She not only works in our boarding kennels but takes on many responsibilities and duties at our local Shelter on the Hill as one of the key people at the Animal Care Center. She is there to handle anything that comes their way. On Saturdays she holds a Meet and Greet at the Thrift Store in Frazier Park, bringing one of the dogs to the Thrift Store for the day to meet people. She says “I am definitely a dog lover! I have 5 dogs at home. Working at Mountain Aire has been an eye-opening experience. Dr Cosko is an exceptional veterinarian and the woman works harder than anyone I know.”
Chad lives in Pine Mountain and joined the team as kennel staff in December 2016. He works at both Mountain Aire Vet and Shelter on the Hill so he can help others whether people or animals. He loves the ocean and surfing. Most of all, he values family and friends above everything.
