Director of Orthobiologics

Read Dr. Daniel's bio

Dr. Daniel Clark is a licensed Naturopathic Doctor who focuses on regenerative medicine and pain management. He helps patients recover from injuries, reduce pain, and return to daily activities — without surgery or harsh treatments.

He earned his medical degree from Sonoran University of Health Sciences, graduating with honors, then completed a two-year residency in regenerative medicine. Before that, he studied kinesiology at Laurentian University in Ontario, Canada.

Dr. Clark's interest in pain management grew from his own experience with sports injuries. When standard treatments didn't work, he found relief through dextrose prolotherapy — which inspired him to help others heal naturally.

Today, Dr. Clark uses many treatments to support healing, including platelet-rich plasma (PRP), IV therapy, supplements, exercises, and nutrition plans. As a triathlete, he understands how important it is to feel strong and pain-free.

Besides treating patients, Dr. Clark takes part in research. He co-authored a study about ketone supplements and exercise performance, published in Frontiers in Nutrition. He has also studied ways to better diagnose and treat concussions.
