I love my experience with this office. Dr Lee, takes the time to make sure she has a clear picture of what is going on and lays out a thorough suggested plan of action. I don't like the idea of having to take medications for anything and she doesn't seem to force it as first choice either. I love how she offers the choice of lifestyle changes with suggestions, which empowers you as a patient. I always enjoy the time I spend with her.
