The cost of treatment is as individual as the treatment itself.
There's no single answer to what treatment costs — because treatment isn't one-size-fits-all. The level of care, duration, and services all shape what recovery looks like for you. One call gives you a clear answer.

Outpatient Services · New York City & Westchester
Outpatient recovery options
that fit your life —
not the other way around.
Mountainside’s outpatient programs make it possible to receive best-in-class addiction treatment without stepping away from work, family, or the responsibilities that can’t wait. With flexible morning, evening, and virtual options in New York City and Westchester, you don’t have to choose between getting help and keeping your life running.
Why Mountainside
We believe in you
before you believe in yourself.
Since 1998, Mountainside has operated from a simple conviction: recovery is possible for everyone. We meet you where you are, and we don’t give up. That’s not a tagline. It’s how we work.
Human Above All
We lead with compassion and follow best practices. Our clinicians, counselors, and case managers are relentless advocates — many of whom have walked this path themselves.
Integrative Care — Mind, Body & Spirit
Clinical therapy, medical oversight, and wellness programming work together in every program. We treat the whole person, not just the presenting problem.
One Size Fits No One
Your treatment plan is built around your history, your circumstances, and the life you’re returning to. We don’t do cookie-cutter care.
We Don’t Give Up
Clients are more likely to complete treatment with us than at any other facility in our class. Our dedicated case managers stay close — between sessions, in moments of crisis, and beyond.
Recovery doesn’t end when a session does. Mountainside’s Recovery Coaching Program pairs with outpatient treatment to provide one-on-one support, accountability, and human connection between sessions — meaningfully improving long-term outcomes for those who use it.
