Dr Lee is very dedicated to his patients;. He demonstrates consideration and thoughtfulness in responding immediately to questions or concerns- even before returning from vacation! When he is not aware of certain, rare issues, he follows up and researches answers that he posts on MyChart. I have trust and faith in his manner, attitude and his willingness to listen to any concerns with rationale replies. He has proven to be consistent as described for over 30 years as my PCP.
