Mark is an excellent physician with a fantastic dry humor. He's a Yankee and for a while you'll only see that Boston stoicism but don't let it put you off. He literally saved my life because he knew to look for an obscure genetic defect and referred me to a cardiac surgeon just in time. Seneca is his RN and Right Hand. Be nice to her she is a tenured professional and an invaluable asset to both the patient and Dr. Wolozin.
