    Dr. Chan has always helped me stay very healthy. I appreciate his knowledge and education. If Dr. Chan were to leave Optum I would follow him.

    Thank you so much for finally helping me get my reflux under control. I was really struggling, but you actually listened to my concerns and broke everything down in a way that made total sense. The treatment plan is already working wonders, and I feel so much better. I really appreciate your patience and how comfortable you made me feel throughout the whole visit.
