Dr. Maryal Concepcion

A Sacramento native, Dr. Maryal Concepcion (she/her) is a Filipinx creator and connector. She attended the University of California at Davis where she graduated in 2005 with a double major in Anthropology (BS) and Evolution & Ecology (BA). She had an unforgettable time as a California transplant when she got her MD at Creighton University in Omaha, NE. It was there she discovered hayrack rides, found her husband, Dr. Jeremiah Fillo, and discovered her love of rural family medicine.


Her residency training was in the unopposed family medicine program at Doctors Medical Center, Modesto, a training extension through the UC Davis Medical School. During her time in training, she returned to Brodstone Memorial Hospital in rural Superior Nebraska to complete proficiency training in performing colonoscopies as part of her rural family medicine concentration.


After residency, she moved to Arnold, CA (home of Calaveras Big Trees State Park) where she worked under the fee for service model with her Husband doing full-scope care for over five years. Though grateful for her experience in this role, she was driven to seek a better way of life and a desire to practice insurance-free medicine and that was when she discovered DPC.
