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 and Ambulatory Service. Being intrigued by surgery, Steve focused more on the surgery aspect of Steinbeck’s practice, such as colic surgery, cryptorchid surgery, hernia repair, and many other surgeries. 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 other 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 equine 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 Dr. 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 North State region. Dr. Steve and Dr. Kevin Terra purchased Cottonwood Veterinary Clinic and Cottonwood Small Animal Clinic in 2015.  In 2014 Dr. Steve received advanced training in small animal orthopedic surgery, he specifically enjoys canine/feline fracture repair and canine cruciate repair. Dr. Steve is also the 3rd year preceptor for Western University of Health Sciences' budding veterinary students, whom he mentors on a routine basis. 

During Dr. Steve’s spare time, he enjoys spending time with his wife Korina, and children Carter, Hayden, and Lily. He also enjoys hunting, fishing, traveling and hanging out with his dog, cats, and horse.

imageDr. Melissa Siegrist

Dr. Melissa Siegrist grew up on a small equine breeding farm near the outskirts of St. Charles, Missouri. It was walking the halls of the equine specialty hospital next door that inspired a 5-year old Dr. Siegrist to pursue a career in veterinary medicine, wherein she could merge her passions for science, animals, and the outdoors. Through the Pre-Veterinary Scholars program, she was pre-accepted to the University of Missouri College of Veterinary Medicine, aspiring to become an equine practitioner. However, her professional interests shifted with growing experience, and she expanded her interests to include reproductive medicine of all domestic species. It was the case diversity and the mountains that called Dr. Siegrist to Northern California. In her spare time Dr. Siegrist enjoys reading, crafting, tea, and all things outdoors.
