Guillermo was born Abel Guillermo Rubio Rodriguez in Mexico City to Dr. Salvador Rubio Morales and Carmen Rodriguez Silva. He was one of nine children and grew up, often caring for his siblings since his mother passed at an early age. Guillermo lived in Cuaútla, Morelos and Mexico City during his childhood and subsequently studied medicine at the Universidad Nacional Autónoma de México. He completed his residency, and fellowship in internal medicine and endocrinology at Henry Ford Hospital in Detroit, Michigan where he met Alyce Dabanoff.
