Ashutosh Kacker, M.B., B.S., M.D.

Upper East Side ears, noses, and throats have their own rhythm. Ashutosh Kacker, M.B., B.S., M.D., keeps that rhythm steady from an office on the fifth floor of 1305 York Ave. The building sits between 70th and 71st, where the neighborhood shifts from brownstones to hospital towers without losing its quiet.

An otolaryngologist here means sinus surgeries, ear tubes, tonsillectomies, thyroid work, and the occasional vocal-cord polyp. Appointments run weekdays; the phone, (646) 962-5097, picks up after the usual 9 a.m. start. No weekend slots are listed, so plan accordingly if the kids’ earaches wait for Monday.

Directions are easiest with the map—York Ave at 70th—and the elevator bank nearest the 70th Street entrance. Bring insurance cards; the desk will want them before the first exam.
