Doctors & Physician's Assistants
Dr. William Crevier
Dr. William Crevier serves as a physician as well as the President and Medical Director of the Center for Primary Healthcare. He received his medical degree from the University of Chicago and completed his residency at Loyola Medical Center. Dr. Crevier is board certified in both Internal Medicine (Adult Medicine) and Pediatrics. In addition to his work at the Center for Primary Healthcare, Dr. Crevier has also been an advocate for access to care and has served as the founding executive director of two Christian Community Health Centers.
Dr Crevier strives to make sure that, in all areas of practice, we don’t look past the person in our efforts to address a medical problem. Though our primary expertise is in medicine and our job is to keep our patients healthy, we also try to acknowledge our patient’s social, emotional, and spiritual needs through our care.
When Dr. Crevier is not taking care of patients, he enjoys taking his wife and six children on long hiking treks into remote wilderness areas in search of breathtaking scenic views.
