Professional, pleasant, and very helpful. Dr. Montgomery gave me plenty of time to ask questions and he gave me information to help me confidently form a plan of action with a medical issue that’s outside of his expertise.
Thank you to a great doctor and staff.

Dr William Lee has been my cardiologist for many years. For even more years he was my ex-husband’s cardiologist. Every visit is thorough and every marker is explained. He is polite professional and very understanding. Five stars every visit.

Dr Lee is thorough, and incredibly perceptive to cardio nuances that go unnoticed by others. This fact is based on the life-saving diagnoses of myself and friends for whom I recommended Dr William Lee. Additionally, the entire support staff is of the highest caliber.
