About Alan H. Wang, MD

Philosophy of Care

My goal is to provide outstanding medical and procedural services in a relaxed and friendly environment. I believe that the first step in taking care of a person, is to establish a good rapport that is based on trust, mutual understanding of our goals and openness in our discussions. I then will offer and discuss the best options of care that is tailored to a person's individual healthcare needs.
