everything i look for in a general practitioner. he's nice and easy to talk to
without being patronizing; he's always on time in seeing his patients; he's
affiliated with a top-notch hospital (nyu) which my parents have explained to
me is very important in case something happens and you need surgery; and you
can get referrals to see specialists without having to see him first. really,
what more do you need? i'm sitting here trying to think of any complaints i
have about him, but i'm really drawing a blank. | review |
