★★★★★“Every time I leave Principle Performance I feel great! Dr. Gontarek really knows how to cure your aches and pains. He is the first person I recommend when athletes come with injuries or movement pattern issues.”

★★★★★“I started seeing Dr. Mike for recurring trap and shoulder pain. He discovered it was actually a thoracic disc issue — not the shoulder at all. Treated the disc and the pain finally went away for good.”

★★★★★“I tore my calf in 2022 and Dr. Mike helped me get back to my activity level. Throughout treatment, deficiencies in other areas that could lead to injuries were diagnosed, addressed, and I was given tools to keep building strength.”
