Board-Certified Specialty Care, On-Site
Red Rock Veterinary Health partners with independent, board-certified specialists who bring advanced surgery, oncology, and internal medicine directly into our hospital. That means your pet can receive specialist-level care in the calm, Fear Free Certified environment they already know — without a referral across town.
These specialists provide their services on-site through a partnership and are not employed by Red Rock Veterinary Health.

Through our partnership with MOVES – Front Range Mobile Veterinary Specialists, Dr. Swiderski brings specialist-level surgical care directly into our Colorado Springs hospital, so your pet can have complex procedures performed in the calm, familiar, Fear Free Certified environment they already know — rather than being referred across town. Dr. Swiderski earned her DVM from Colorado State University in 2002, completed a small animal medicine and surgery internship at VCA West Los Angeles, and returned to CSU for a combined master's degree and three-year surgical residency, achieving board certification through the ACVS in 2008.
