Dr. Steve Loncosky
Owner, Veterinarian

Dr. Steve Loncosky attended Cal Poly, San Luis Obispo for his undergraduate degree in Animal Science and a minor in Equine Science. While at Cal Poly he also became certified as an Equine Dentist where he worked with several veterinarians providing proper equine dentistry to their client’s horses. He then headed to Los Angeles County to complete veterinary school at Western University. After graduation, Steve completed an internship with Steinbeck Country Equine Clinic in Monterey, California. Throughout his time at Steinbeck, he rotated between Surgery Service and Ambulatory Service. Being intrigued by surgery, Steve focused more on the surgery aspect of Steinbeck’s practice, such as colic surgery, neurectomies, arthroscopies, and many more. In his spare time during his internship, Steve volunteered on many outreach trips locally, nationally, and internationally. These trips provided veterinary services to communities in need; such as spaying/neutering dogs/cats, equine castrations, and routine care. Upon completion of his internship, he and his wife, Korina, moved to the Center Ranch in Texas. As a resident veterinarian on a high caliber cutting horse ranch, Dr, Loncosky provided lameness care to the resident horses in training and produced embryos for their large embryo transfer program. He assisted with cattle work on the ranch and even helped open a small animal clinic that offered affordable services to the local community. After a stint in Texas, and Korina pregnant with Carter and Hayden (the twins!), they decided to head back to their roots. Since Korina grew up in the great community of Cottonwood, and Steve loved Northern California, they knew this area would be a great fit. Dr.Loncosky joined the Cottonwood Vet Clinic team in 2012, specializing in horses, but providing services to all animals in the Cottonwood region. Dr. Steve and Dr. Kevin Terra purchased Cottonwood Veterinary Clinic and Cottonwood Small Animal Clinic in 2015.

During Dr. Steve’s spare time, he enjoys spending time with his wife Korina, and boys, Carter and Hayden. He also enjoys hunting, fishing, traveling, hanging out with his two dogs, and riding his horse, Moonshine.

Dr. Allison Tedesco 

Dr. Allison Tedesco grew up in northern California. Some of her earliest and fondest memories are living next to her grandmother’s 3 1/2 acre woods. This is where her adventures with animals began, and her dreams nurtured listening to stories from James Harriots’ All Creatures Great and Small.
Allison knew at a young age she wanted to work with animals. Shortly after high school she decided to pursue her lifelong dream to become a Veterinarian. She spent 5 years at the wild and beautiful campus of Murdoch University Australia, where she earned her DVM degree. During summer breaks she had the wonderful privilege of seeing England, Wales, Scotland and Indonesia. 
But there is really no place like home and being near family, so she is happy to be back in Northern California living her dreams as a Veterinarian! 
Allison started her career at Haven Humane, moving out to Millville Clinic, and currently found a home at Cottonwood Vet both small and large Animal locations. 
When she has time off, she can be found with her dog, Digit, cat Bobby, reading a good book, running, swimming, snowboarding and just having fun with friends and family.
