Founder & CEO
U.S. Army Combat Veteran · B.S. Physiology (Phi Beta Kappa), A.S. Chemistry · Published researcher
Onur is the founder of Shroombiosis and a U.S. Army combat veteran. After years in an industry full of underdosed, overpriced "proprietary blends," he set out to build the opposite: supplements with every dose printed on the label and every batch tested.
His background is academic and lab-deep. He earned a B.S. in Physiology from the University of Arizona — graduating Phi Beta Kappa — alongside an A.S. in Chemistry, then completed four years of medical-school coursework and logged more than 1,000 clinical hours. He's also a peer-reviewed published researcher, with work spanning clinical nutrition and molecular spectroscopy.
That training — reading studies, respecting dose, distrusting marketing — is the lens behind every Shroombiosis formula, which he develops alongside his wife, Danielle, a pharmacist. He served — and deployed — with Jon Klipstein, whose company now makes and ships the blend.
He writes about functional mushrooms, physiology, and how to actually read a supplement label.
