I saw dr hennigan when my dr was out. I liked her a lot she was thorough and dealt with me in a caring manner and really listened. Punctuality was an issue but you can't have both punctual and a dr that listens to everything if practices are going to schedule appts so close. I believe you need to find your fit but not bash drs because they don't fit you. I think she's perfect for my retired mom to see. I'm always in a hurry I.E. I see lightfoot.
