Mountainside Chelsea is a New York City treatment center offering PHP-level day treatment for adults dealing with substance use, including kratom, which it is one of just a handful of area providers to treat directly. Operating since the 1990s, the facility is CARF accredited, a distinction shared by a minority of nearby programs, and it maintains a smoke-free environment.

Its approach includes mindfulness-based practices alongside wellness programming, and it welcomes veterans and military clients. The combination of day treatment structure with a smoke-free, wellness-oriented setting makes it a fit for people in the New York area looking for a structured, accredited outpatient option close to home.
