Outpatient Addiction Treatment in Chelsea, New York City

Mountainside NYC offers outpatient addiction treatment services for adults, adolescents, and families who need flexible support in Manhattan and the surrounding New York City area.

Partial Hospitalization Program (PHP)

Mountainside Huntington’s Partial Hospitalization Program (PHP) offers intensive support for clients who need more structure than the usual traditional outpatient care but do not require 24/7 residential treatment. PHP can be a helpful step after residential care or a strong option for people who need focused support while continuing to live outside of an inpatient setting.

PHP provides structured clinical programming five days a week, giving clients continued daytime support as they stabilize early recovery, address co-occurring mental health needs, and practice the skills needed for daily life.

Intensive Outpatient Program (IOP)

Our Intensive Outpatient Program (IOP) provides a higher level of outpatient support for people who need regular, structured care but do not require residential treatment.

Our IOP helps clients better understand their substance use, identify triggers, strengthen relapse-prevention skills, and develop healthier patterns that support long-term recovery.

Outpatient Program (OP)

Our Outpatient Program (OP) offers continued support for anyone stepping down from a more intensive level of care or who would benefit from ongoing treatment with greater flexibility. This level of care combines therapeutic guidance with practical recovery planning.

OP focuses on helping you rebuild stability, improve relationships, manage stressors, and continue to make progress in recovery while maintaining work, school, family, and daily responsibilities.

Recovery Coaching

Recovery coaching gives you practical, one-on-one support from a trained coach who fully understands the recovery process. This style of coaching can be used on its own or alongside other clinical treatments, depending on your needs.

This makes it a helpful option if you are new to recovery, stepping down from an intensive program, or looking for extra support outside of formal sessions. Your coach will meet with you one-on-one to set goals, create a plan, build accountability, and tackle new challenges.

Clients may need clinical care, holistic approaches, family involvement, medication-assisted treatment, peer support, alumni services, continuing care, and community connections.

Family Therapy

Addiction often affects the entire family system, creating stress, confusion, broken trust, and communication challenges. Family Connections Therapy gives loved ones a supportive space to begin working through those challenges with gentle guidance from Mountainside’s clinical team.

This program is designed to help families better understand addiction, rebuild trust, improve communication, establish healthier boundaries, and support their loved one’s recovery while also caring for their own healing.
