Born and raised in Colorado, Dr. Mark Motichka has called Parker home since 3rd grade, other than spending 7 years elsewhere. He completed Tightrope surgery training through Arthex in 2007 and is pleased with the results of this technique, which most closely mimics the natural function of an intact CCL. Dr. Motichka has been involved in various veterinary practices and is currently a key figure at Parker Center Animal Clinic [citation][3][4].
