  • "I can't say enough about how much improvement I have seen in both my horses after just one acupuncture session with Dr. Drost. One mare went from unrideable due to back pain to comfortably competing the next weekend. Dr. Drost's treatment and aftercare instructions helped my gelding to successfully recover from a tieup and win BC a week later. I am so happy to have such a valuable resource available in my area."
