I have been a long term patient of Dr. Flershem and despite moving farther away, I continue to drive the distance to have her manage my care. She is incredibly thorough, compassionate and a real problem solver. Excellent physician!

Dr. Flershem is my very own guardian angel. Her persistence in sending me back to doctors when certain tests appeared inconclusive (that she knew could be serious) helped to catch early stage cancers two times. She is knowledgeable, compassionate, and dedicated to her patients. I highly recommend her.
