Ronald Hanson Jr., M.D.
Ronald Hanson Jr., M.D. is a Sports Medicine specialist with extensive experience performing regenerative medicine procedures. Dr Hanson lectures and trains physicians in the US and around the world to use musculoskeletal (MSK) ultrasound for regenerative orthopedic procedures. He is actively involved with sports medicine societies and the International Cellular Medicine Society to develop training programs, guidelines and curricula that promote excellence in both regenerative medicine and MSK ultrasound.
Dr Hanson combines many approaches to guide a patient toward healing and restoring function. At the Centeno-Schultz Clinic, this translates into using (and developing) the most advanced regenerative platelet and stem cell therapies in the US combined with improving structure, alignment, nerve function, stability and pain. He is also at the forefront nationally in developing minimally invasive nerve, tendon, ligament and bone spur removal procedures using MSK ultrasound.
Dr Hanson completed his training and practiced in Minnesota and Utah, where he had developed a sports, regenerative medicine and MSK ultrasound practice before joining the Centeno-Schultz Clinic in early 2010. He is privileged to have the companionship of his wife, Jodi, and their daughters Aly and Madi. He enjoys all types of outdoor recreation, traveling, hiking, scuba diving and Scouting.
Ben Newton, M.D.
Dr. Newton completed his residency in Burlington, VT where he actively participated in sports medicine coverage opportunities at the high school and university levels. He also covered several US Ski and Snowboarding events in Killington, VT.
Dr. Newton comes to Colorado straight out of his Primary Care Sports Medicine Fellowship in Cincinnati, OH where he worked with various teams at high school, college and professional levels. He enjoyed time at Xavier University (Division I) and College of Mount St. Joseph (Division III) where he covered football, basketball, soccer, wrestling, lacrosse and rugby, as well as being one of the sports medicine physicians for the Cincinnati Reds. He also provided regular game coverage and medical care to the Cincinnati Commandos (men’s indoor professional football) and the Cincinnati Sizzle (women’s full contact football). He had the opportunity to do medical coverage for the USA Olympic Boxing Last Qualifier, the Cincinnati Marathon and the Coaches Classic – Gymnastics Tournament (levels VII – elite).
During his fellowship, Dr. Newton was able to learn and use musculoskeletal ultrasound (MSK US) for the diagnosis and treatment of many acute and chronic musculoskeletal injuries. He anticipates further development of his diagnostic and procedural skills, including the use of fluoroscopy and MSK US, this year with the physicians at the Centeno-Schultz Clinic as a fellow in interventional orthopedics. Dr. Newton is also very excited to further his understanding of regenerative medicine and looks forward to being involved in research and development of stem cell use over the next year.
Dr. Newton is board certified in family medicine and sports medicine.
He loves being outdoors, playing sports and hanging out with his family (wife and two young kids).
