Biografía
Michael Portillo, MD, earned his medical degree at Universidad Dr. José Matías Delgado in El Salvador, where in his final year of schooling he provided free medical clinics in rural villages, treating acute and chronic illnesses common to the region. After completing a year as a primary care physician at the Paisnal Health Clinic, also in El Salvador, he completed a clinical preceptorship at the Sky Lakes Medical Center in Klamath Falls, OR.
Dr. Portillo credits his father, a chiropractor, for his path into medicine. “The connections he had with his patients is what impressed me and made me want to pursue medicine.” That impression influences how Dr. Portillo practices medicine today. “I try to empower the patient to be more conscious of their health. That way they can help me better understand their needs.”
Originally from Burlingame, CA, Dr. Portillo moved to El Salvador, his father’s home country, when he was 14, but his roots in Tuolumne County run deep. His grandparent’s owned and operated the dry goods store in historic Columbia, where his mother would spend summers away from San Francisco working in the store.
