Cierra Dedeker DVM – Practice Owner / Veterinarian

Dr. Cierra Dedeker grew up around horses, large and small, and has a background in equine performance.

She is a graduate from California Polytechnic State University, San Luis Obispo with a Bachelors in Animal Science and a minor in Equine Science. Following graduation, she was selected by the Atlantic Veterinary College on Prince Edward Island, in Canada for a Doctorate of Veterinary Medicine.

After veterinary school, Cierra completed an internship at the Alamo Pintado Equine Medical Center in Los Olivos, California, a referral equine hospital with a diverse and exciting caseload. After a one year rotating internship through internal medicine, surgery, diagnostic imaging, and anesthesia, she was hired as a veterinary associate at Monterey County Equine and worked with the hunter-jumper circuit in Pebble Beach and Carmel, California. After a year, she moved to the Pacific Northwest to start her own practice in the performance horse world. Her passion has always been in the sports medicine arena, with current diagnostic modalities and treatment options. She currently lives in Boise, Idaho with her husband, Chuck, and one-year-old daughter, Madelyn, where they are building a new home in the foothills. Outside of veterinary medicine, Cierra enjoys all adventures outdoors, including riding her horses, Nash and Peter, trail running, snowboarding, fly fishing, and hiking with her husband and their two labradors, Jack and Lucy.

Madelyn Dedeker Veterinary Assistant

Madelyn has been working for her Mom since she was 5 days old. She loves all horses, especially minis, but has an extreme love of unicorns and her horse Hilltop. When she’s not working, she’s in the saddle, on the boat, or on the ski hill.

Charles Dedeker – Facilities Manager

Charles Dedeker serves as support staff and takes care of daily tasks and keeps the practice vision innovative and on task.

Shelby VanSlander – Veterinary Technician

My name is Shelby and I have had the honor to be a veterinary assistant for Dr. Dedeker since I was in high school. In 2019 I graduated from Oregon State University with an Animal Science degree with an Equine focus. Once I graduated, I moved to Kentucky for the Kentucky Equine Management Internship where I was working with racing thoroughbreds. After the internship, I accepted the Stable Assistant Manager position at Sun Valley Resort. Here I manage the draft horses for sleigh rides in the winter and trail horses in the summer. In my free time, I like to play mermaids in the lake with the tiny assistant Madelyn, shred the mountain, and go camping with my family.

Shelby Ketcham – Veterinary Assistant

Shelby Ketcham is the owner and founder of SJR Horsemanship and is based out of Boise Idaho. She trains horses and also runs a lesson program for kids and adults. She strives to develop a strong and trusting relationship between horse and rider, both on the ground and under saddle. A few examples of what she teaches are Liberty work, trick training, groundwork and horsemanship for all levels and disciplines. She has been competing in many disciplines with different breeds for over a decade including many high placing’s in Extreme Mustang Makeover Competitions. Her most recent achievement is winning the 2021 Impact of the Horse Competition held in Heber City, Utah.

Caitlin Gaffney Veterinary student & Assistant

Caitlin was introduced to horses at the age of ten when she got her first mare, Honey. In 2021, she welcomed a second horse – Honey’s first foal – Zara. Caitlin and Honey compete in dressage, currently working towards their bronze medal. Her introduction to horses was shortly followed by her introduction to Dr. Dedeker, who has been instrumental in both Caitlin’s and her horses’ lives. Her time at Peak Performance Equine has provided her with many new skills and widened her horse knowledge. This experience has been immensely helpful in preparing her for a career in veterinary medicine – both deepening her love for horses and the profession. Caitlin graduated from Oregon State University in 2022 with a Bachelor’s of Science in Animal Science with a focus in pre-veterinary medicine and a minor in chemistry. She is currently in her second year of vet school at Oregon State Carlson College of Veterinary Medicine (class of 2026), with a focus in equine medicine.

Heather Edlund Practice Manager

Heather grew up on a farm in North Carolina and joined our team after moving to the Flathead Valley in 2022. She has a Bachelor of Science in Physiology from Appalachian State University. Heather first worked in healthcare as a resident care coordinator but has shifted to the veterinary world due to her love for animals. “Meeting Dr. Dedeker has allowed me to merge my two biggest passions of horses and healthcare into one job. I feel fortunate to have coworkers and clients who care so deeply about their animals and will do anything to provide the highest quality of care.” When Heather is not working, you can find her in her garden and spending time outdoors with her daughter Hazel.

Jean Collins Veterinary Technician

Jean Collins is a dedicated and compassionate veterinary assistant. She has a Bachelor of Science in Wildlife Biology from Pennsylvania State University. Born and raised in Philadelphia, Pennsylvania, her interest in animals began at a young age. Her formative years were spent at a stable just outside the city where she developed a strong connection to horses and their training. She is experienced in caring for and riding a variety of horses from many backgrounds. Currently she runs her own riding lesson program, specializing in foundational equitation with a focus on biomechanics. She works with her students and their horses to be the best possible team.
