Plant-based vitamins founded by a Medical Doctor. Our founder. Todd J. Pesek, M.D., (lovingly referred to as “Dr. Todd”) is a fourth-generation Appalachian Root Doctor who went to medical school. After graduating from Ohio State medical school, Dr. Pesek spent time traveling the world as an academic ethnobotanist researching traditional medicine, nutrition, and plants. He returned back to Cleveland, Ohio where – more than 15 years ago – he launched his private medical practice. Our products are formulated to reflect the nutrient insufficiencies and deficiencies that Dr. Pesek documented in reviewing thousands of his patients' blood work.
