Arnab Datta, MD

Arnab Datta, MD, started his private practice in New York City for patients who need more than a brief medication visit. His work combines psychiatry, psychotherapy, addiction treatment, controlled-substance expertise, Suboxone care, couples and family work, EMDR, and customized meditations – to make the behavior change second nature.

People often come here when previous care has felt incomplete. Perhaps you didn’t fall into any clear-cut DSM-5 categories, perhaps your unique personality didn’t quite fit the meds. There are parts of your mind that you didn’t reveal to the doctor or to yourself; thus, your layered story wasn’t fully understood. Dr. Datta’s role is to understand the full picture, symptoms, history, relationships, medication, addiction, personality, and emotional blind spots, so you are fully seen, heard, and understood.

This practice began in Manhattan and remains anchored in a New York City level of attention to detail and skill. The main office is located on East 44th Street and 5th Avenue, near Grand Central Station, Rockefeller Center, and Bryant Park. However, Dr. Datta is also licensed and sees patients in Chicago, Miami, Los Angeles, New Jersey, and North Carolina. Appointments may be available in person or by secure video.
To begin, call +1 877-376-4560 (click to call now) – this is a 24/7 answering service where a live person will pick up. Then Dr. Datta’s personal assistant will call you back during business hours the same day or the next day. You can share what is bringing you in, ask initial questions, and hear whether Dr. Datta’s practice may be the right fit before beginning treatment.

What is a Discovery Call?

Before beginning care, potential patients are scheduled for a discovery phone call. This is a short preliminary conversation where you can convey what is bringing you in, ask initial questions, and hear whether Dr. Datta’s practice may be the right fit.

DHD, relationship issues, trauma, or a major life decision. The goal is to begin understanding not only the immediate concern, but also what may be driving it underneath. 

The discovery call is not a formal appointment. However, you will find that the discovery call is Unique and Deep in that Dr. Datta may understand things about you that may not have been seen before. Dr. Datta clarifies what he can and cannot provide even before the first appointment, which most people don’t hear until they are in the office. Care often begins with a 3-appointment starting package, which allows enough time to understand your full picture and the treatment. You will see that the understanding that you receive is deep, even in the 1st session.

Education & Career

Discovery Call

Before beginning care, potential patients are scheduled for a discovery call. This is a short preliminary conversation where you can explain what is bringing you in, ask initial questions, and hear whether Dr. Datta’s practice may be the right fit.
Although it is brief, the discovery call can often provide an early sense of how Dr. Datta thinks clinically. Patients may discuss medication concerns, addiction patterns, depression, anxiety, ADHD, relationship issues, trauma, or a major life decision. The goal is to begin understanding not only the immediate concern, but also what may be driving it underneath the surface.

The discovery call is not a full psychiatric evaluation and does not replace treatment. It helps clarify what Dr. Datta can and cannot provide before the first appointment. For patients who move forward, care often begins with a three-appointment starting package, allowing enough time to understand the full picture and the likely direction of treatment.

To schedule a discovery call, please call +1 877-376-4560.
