Meet Our Team
Dr. Mark Cantieri, DO, FAAO
Dr. Mark Cantieri has spent over forty years helping people break free from chronic pain. As a specialist in osteopathic manipulative therapy, regenerative medicine, and non-pharmaceutical pain management, he focuses on treating the root cause rather than just the symptoms.
He has been medical director at a hospital, taught hundreds of courses, served as president and board member for several professional organizations in medicine. As Dr. Klauer often says, “he’s a diagnostic wizard and a sage.” He started a practice nearly 40 years ago and we are honored to work side by side with him here. His expertise in prolotherapy, platelet-rich plasma therapy, and musculoskeletal rehabilitation has made him a leader in the field of osteopathic medicine. His hands-on approach has helped countless patients regain mobility and function without relying on medication.
He has spent much of his career mentoring the next generation of osteopathic physicians. Outside of the office, he enjoys life’s simpler pleasures, like spending time with family, engaging in thoughtful conversations, and sharing his knowledge with those eager to learn. If Mark isn’t seeing patients you will find him with his wife, outside with his beloved dog Gus, or spending time with his 16 grandchildren.

We’re proud to serve Northern Indiana with two convenient locations designed to deliver exceptional care close to home.
