AboutNYC Psychiatric Associates

Taking care of one’s mental health is just as important as taking care of one’s physical health. However, people are less likely to consider any form of mental health treatment until it becomes absolutely necessary. Instead of waiting for the treatment to reach its worst state, The NYCPA Team provides customized treatment to help patients through it.

Mental health issues can occur together and influence one another. In these cases, treating one issue instead of both can result in the untreated issue becoming worse. At NYC Psychiatric Associates, we can provide addiction treatment, along with therapy and counseling services. Our goal is to help patients find effective coping and treatment methods to live a healthier lifestyle.

There is no reason to struggle with an addiction or mental illness alone. Call us to seek help today.

Our team establishes a welcoming and judgment-free environment for patients. We can help people be themselves, let down their guard and receive the treatment they need. While we will guide patients through the treatment process, many will continue with their daily life during it. Over time, the patient may not need as many appointments with us and may continue by seeing support groups with those who have similar struggles.
