Dr Willenborg is attentive, personable, sharp, and does everything himself, including taking blood and weighing me. No matter how sick I have felt, he always manages to make me laugh.

Dr. Willenborg is a rare doctor who spends time with his patients to understand their overall health and well being. He is caring and offers a comprehensive approach. I am only saddened that he is not taking new patients so I cannot refer my children who are leaving the pediatric phase. Dr. Willenborg is the best physician I have ever met.

Dr Willenborg is so smart and informed about modern medicine. Meticulous and extremely serious about keeping his patients healthy. An unbelievably intuitive and spectacular ability to diagnose.
