Residential Treatment & Transitional
Living for Young Adults in Maine

Step Into Life

Sometimes, feeling stuck just means you’re on the edge of something new.

We help young adults ages 18 to 30 take the step from potential to progress, finding independence and self-worth along the way. If you are a young adult who is struggling with motivation, or overwhelmed by life’s demand—or love someone who is—you’re not alone, and you’re not broken.

Cornerstones of Maine's residential treatment and transitional living programs accept individuals as they are. Our team is here to support them wherever they are in their journey. It’s all focused on giving young adults the structure, support, and real-world experience they need to step into the life they’re meant to lead. Ready to get started?

The Cornerstones Continuum of Care

Every young adult needs a different mix of tools, techniques, and support to succeed. That’s why we’ve built a comprehensive continuum of care that supports individuals at any level of growth. Clients enter at the program that is the best fit for their needs, and progress according to their own clinically appropriate timeline.

Residential Treatment Center

Our short term residential treatment center offers mental health stabilization for young adults with a broad range of psychiatric presentations and profiles.

Young Adult Transitional Living

Our transitional living program places young adults in collaborative living spaces with supportive professionals based in the milieu throughout the day. Our clients are engaged in real-world activities of daily living, and provided with a comprehensive holistic treatment approach that includes psychotherapy, executive functioning coaching, academic support, health and wellness, and interpersonal growth.

Transitional Living

After Care & Independent Living Support

The goal and core mission of our entire program is to help each young adult become successful on their path toward independence, self-reliance, and autonomy. In the stepdown phase, clients experience a greater level of autonomy, while still enjoying the safety net of our community and care providers.

Aftercare

Clinical Excellence

Traditional treatment models only focus on eradicating symptoms. We focus on building momentum.

Growth doesn’t happen in a vacuum, and independence isn’t built overnight. That’s why we take a comprehensive, real-life approach—balancing clinical support, executive functioning coaching, academic and career guidance, and practical life skills. This isn’t just therapy. It’s training for life.

Our clinician-owned, fully-accredited program combines evidence-based therapeutic modalities with real-world experiences, including:

Individual and group therapy with experienced clinicians
Life skills development in a supportive community setting
Educational and vocational support tailored to your goals
Family collaboration and coaching
Medication management when needed
A comprehensive approach to wellness and independence

Community Support

We're more than a transitional program – we're a community dedicated to helping young adults find their footing in a world that often feels overwhelming.

Our model is designed for struggling young adults—those with untapped potential who need new tools, a new environment, and a supportive community to thrive. Our therapeutic community is:

Structured (But Flexible)

We offer a guided path to independence, not a one-size-fits-all program.

Comprehensive

Clients experience a blend of therapy, coaching, mentorship, and hands-on life experience.

Welcoming

Clients live in a real-world setting where they can practice independence in a safe, supported way.

Results-Driven

Everything we do is designed to help young adults gain skills, build confidence, and step forward with clarity.

Family Partnership

We understand that family is an integral part of the journey to independent adulthood. Our program includes regular family coaching and communications, ensuring that parents and loved ones have the tools and understanding to support each young adult’s growth effectively. We believe in building strong foundations for the entire family system.
