Mark Hancock, MD MPH, founded the Humanizing Medicine in Atlanta together with his wife Enid in 2015. The clinic is strongly rooted in the couple’s belief that everyone should have quality integrative healthcare options. Dr. Hancock has worked with Anthroposophic medicine, which originally introduced mistletoe as a therapeutic option for cancer 100 years ago, for his entire professional career.

Dr. Hancock’s  journey through life has been full and varied, and has taken him through art, philosophy, science and even some farmwork before ultimately landing in medicine at Humanizing Medicine. Read about his journey below.
