Dr. Theresa Les is an astounding physician and so are her nurses and office staff! They work cohesively to answer calls back fast, do paperwork and scheduling fast, prescriptions get done fast, etc. Best office I have ever been to! Secondarily Dr. Lee is one of the best doctors  I've ever had, she is thorough and patient, kind and smart. I feel I'm in good hands with her and am grateful for her ongoing care!
