The American Institute of Stuttering has its headquarters in NYC ([www.stutteringtreatment.com](https://www.stutteringtreatment.com)). They also have a location in Atlanta and offer online services as well. The National Stuttering Association ([www.westutter.org](https://www.westutter.org)) has two chapters in NYC, one in Manhattan and another in Brooklyn Those are two good options, but hopefully others will chime in
