I dont know any Gyn in Manhattan, but know from experience the doctors associated with LIJ(in Long Island) are the best. Dr. Joan Altman-Neumann used to be my GYN, and i assure you that she was one of the best GYNs ever. I am just sharing my experience, but am not sure which insurances she accepts.
good luck,
