Dr. Hadar Lev-Tov is a board-certified dermatologist with extensive research experience. Throughout his training and in daily practice, he has always believed that the key to achieving health for his patients is grounded in his ability to truly connect to their experiences and perceptions of health and well-being. Maimonides, one of the greatest philosophers of all time realized that human knowledge, often represented as "science," is limited. As a physician, he feels he would be a fool to believe all is known. Maimonides said, "The physician should not treat the disease but the patient who is suffering from it." LearnSkin is his journey to a better understanding of his patients.
