About Dr. Clark Store

In 1993, Geoff Clark founded the Self Health Resource Center (SHRC) at his mother Dr. Hulda Clark’s request, to create supplements free from what she considered toxic manufacturing chemicals. This endeavor led to the establishment of a company committed to producing the purest supplements, a principle that has steadfastly remained at its core. The company saw a significant transition in 2006 when Oskar Thorvaldsson acquired it and expanded its mission by manufacturing one of Dr. Clark’s key inventions, the Automatic HOT BACKWASH Whole House Water Filter, with Geoff Clark continuing as a consultant to ensure ongoing improvements and adherence to Dr. Clark’s strict purity standards.
