Sujal Kotadia, MD

Staff Psychiatrist

Dr. Kotadia is a board-certified psychiatrist who completed his psychiatry residency training program at Nassau University Medical Center in Long Island, NY. After completing training, he has been practicing outpatient psychiatry and specializes in the evaluation and management of major psychiatric disorders, including depression, and anxiety. He uniquely combines his education, training, and practical experiences into specialized treatment plans. Typically, he offers this in conjunction with supportive or emotionally focused therapy in 30-minute follow-up visits. However, occasionally Dr. Kotadia may believe that additional therapy is also needed and ask that you bring a therapist into your care team to provide the best outcome. A story that Dr. Kotadia came across years back still inspires him each day. A man was taking a morning walk at the beach. He saw that along with the morning tide, came hundreds of starfish. When the tide receded, the starfish were left behind and would die in the morning sun. While the tide was fresh, and the starfish were alive, the man took a few steps, picked one up and threw it into the water and continued throwing starfish back into the ocean. Behind him was a stranger who couldn't understand what this man was doing. He caught up with him and asked, "What are you doing? There are hundreds of starfish. How many can you help? What difference does it make?” The man did not reply, rather he took two more steps, picked up another one, threw it into the water, and said, "It makes a difference to this one.”With this story as his motivation and ultimate objective, it has always been Dr. Kotadia's goal, with each patient, to provide superior services.
