About Us

Grand Medicine is a private company in Lake San Marcos, California, directed by retired Traditional Naturopath Leonard Mehlmauer and Nenita Sarmiento.  We began clinical practice in February 1972.  Ever since, we have been teaching, studying, and researching in the Eyology sciences, health, and higher ways of living.

Hailed by the late Dr. Bernard Jensen as “one of the pioneers of Iridology”, we are considered by our peers as the world’s leading authority in Sclerology.  Grand Medicine offers highest quality courses in all three Eyology sciences: Physical Iridology, Personality Iridology, and Sclerology.  We have authored textbooks in each of these sciences.  Our experience, product quality, research, brand, and intensity are our integrity.
