About Dr. Mary Chao

Please note: existing patient visits are shorter than the time required to assess new patients. Any new patients who book their appointment in an existing patient time slot will likely need to be rescheduled. Selecting the appropriate time allows our staff to provide the attention needed for the highest level of service. Controlled substances are typically not prescribed during new patient visits. Dr. Mary Chao earned her Doctor of Osteopathic Medicine degree from Michigan State University. She completed both her internship and residency in Internal Medicine at Ingham Regional Medical Center. Before beginning her role as an internal medicine provider at McLaren Medical Group, Dr. Chao was involved in basic science research and holds a master's degree in biochemistry.
