Dr. Ly earned her doctor of osteopathic medicine at Midwestern University in Downers Grove, Illinois. She completed her internal medicine residency and gastroenterology fellowship at Advocate Lutheran General Hospital in Park Ridge, Illinois.

Dr. Ly knew she wanted a career in medicine since she was a child. She worked as a transporter at a local hospital through college and knew she had made the right decision. She chose to specialize in gastroenterology after losing her mother to colon cancer.

Dr. Ly enjoys spending time with her family, traveling, cooking and reading.

Dr was friendly and listened to answers of symptoms that I gave. Didn't jump to conclusions on things and was understanding in ordering tests that would help diagnose my problem without going overboard due to a high deductible with my health insurance plan.
