Dr. Zulia Frost
MD Co-Founder & Head of Clinical
"Innovative therapeutic technologies have been my life’s work. With a foundation in both mainstream medicine and Traditional Chinese Medicine, I’ve spent three decades learning, refining, and applying approaches that truly change lives. My mission is simple: translate complex knowledge into practical solutions that help people feel better, move better, and live better.
Photobiomodulation has shown remarkable success in restoring function and relieving pain, and it’s why I’m committed to making this technology accessible in every home. As co-founder and Clinical Director of Recharge, I continue my work with Red Light Therapy and FlexBeam, bringing science, experience, and heart together for real-world results.”
