Took care to evaluate multifaceted issue as to best way to treat not to cause harm," & worth of tests, thought there possibilities of conversative tests to understand the problem. Listens carefully. Best dr. ever! Follow up by letter is done. Refers to "experts" when needed after thoughtful when needed. She thinks aloud about reasons of needed care. Allows my added input. She REALLY cares about the patient. She is everything skilled to be an OUTSTANDING primary care doctor!
