Ken Ceder

Executive Director at Ken Ceder

Dr. John Ott inspired my life-long passion for the effects of full-spectrum sunlight on biological organisms, including humans. Daily light hygiene is vital for human health, a message that I've been advocating for more than 30 years as well as now as the director of Science of Light (SOL), a 501(c)(3) nonprofit.
