Dr. Marker helped me overcome anxiety I had been feeling for a few years, and he helped me quickly. I thought the whole therapy thing would take years and years, but I felt better within the first few sessions and I take comfort with the knowledge that I have a friendly, encouraging doctor available right in Manhattan. I highly recommend Dr. Marker!
