She also received General Practice Residency (GPR) training at the Ann Arbor Veterans Hospital and the University of Michigan Hospital, during which she gained experience treating medically compromised patients and individuals with complex dental needs.

Dr. Cheng maintains memberships in the American Dental Association, Michigan Dental Association, and Academy of General Dentistry.
