Gregory Sayer MD

Dr. Sayer completed his medical degree and psychiatry residency at UCLA, followed by specialized fellowship training in child and adolescent psychiatry at New York-Presbyterian Hospital (Columbia and Cornell). He began his private practice in New York while serving on faculty at NYU Langone Health as a Clinical Associate Professor of Psychiatry.

Being licensed in CA and NY can be helpful for those who split time between both states. This can be especially convenient for adults who are bicoastal for work or young adults in college or graduate school in one state and family is in the other.
