in Sag Harbor NY |
As busy as Dr Montellessi is he called me 4 times until he got me.Now that is a concerned Dr
in East Setauket, NY |
Dr. Montellese is compassionate and sincerely committed to my remaining healthy. Overweight, I am seeing the doctor due to a problem with one of my heart valves. On my penultimate visit, the doctor urged me, kindly, to lose weight while my heart was in relative good shape. Another doctor started me on a diet drug; after my latest visit at which the Dr. heard I was taking a possibly valve-damaging drug, he called me at 6:30 in the evening to reassure me that he'd researched the drug's safety.
