 VETERINARIAN 

Dr. Erica Koller grew up in Edgemont, South Dakota, where a ranching background and close-knit community instilled in her a deep respect for animals, hard work, and service. Those roots inspired a lifelong commitment to caring for both animals and the people who depend on them. She earned her undergraduate degree from South Dakota State University in Brookings and her Doctor of Veterinary Medicine from Iowa State University.  Dr. Koller has extensive experience in small animal surgery and bovine obstetrics. She is especially passionate about herd health, preventive care, and practical solutions tailored to rural communities. As the daughter of a local rancher, she understands firsthand the challenges and responsibilities of rural veterinary medicine and brings both skill and compassion to every case. Throughout her career, Dr. Koller has continually sought opportunities to grow, lead, and give back to the profession. She was honored with the South Dakota Veterinary Medical Association Emerging Leader Award in 2018 and remains dedicated to building strong veterinary values in others. Her commitment to education shines through the development of a veterinary student externship program and the creation of a veterinary assistant apprenticeship program at CRAH, both designed to provide meaningful, hands-on learning experiences. Outside the clinic, Dr. Koller and her family, husband Dustin Ross, son Tucker, and daughter Harper are actively involved in the community they proudly call home. While they enjoy traveling together, they’ve yet to find a place that compares to Edgemont. Dr. Koller loves sharing her passion for rural traditions and values while embracing modern technology to advance veterinary care and strengthen the future of the profession.
