Dr. Tran and his staff are the epitome of compassion, competence and professionalism. Patients are made to feel like individuals and the office runs like a well oiled machine. If we could clone their procedures no one could EVER complain about health care. Triage is handled flawlessly and it is very reassuring to begin a visit with a familiar face. Central triage system would undo that vital first contact and eliminate that sense of being known.
