Are you exhausted from masking your energy and authentic self? If you suspect you have ADHD or feel you were given the "wrong instruction manual" for life, you are in the right place. A lifetime of trying to "act normal" has left you in a cycle of people-pleasing, perfectionism, and deep-seated shame. You constantly feel like you're "too much" or, paradoxically, not enough, making it hard to trust your intuition or show up authentically in relationships. My passion is helping teens and adults break free from these exhausting, trauma-driven patterns and reclaim their worth.

For individuals, I offer a trauma-informed path to heal relational shame, focusing on the impact of attachment wounds and complex trauma on the self. For couples, I help build resilience against emotional chaos. If conversations shut down due to criticism, defensiveness, or withdrawal, I teach systemic regulation to recognize triggers and strengthen intimacy

It takes immense courage to admit you're exhausted and need a change. If a lifetime of holding back has left you feeling ashamed and disconnected, please know that your struggles are valid. You are not "too much," and you are not broken. You deserve a life where you feel seen, connected, and authentic. I'm here to support you in this journey.

C.L.I.M.B. for Teenagers

Hosted by

Sienna Forest

C.L.I.M.B (courage, learning, integration, mindfulness, becoming) is an 8-week indoor therapeutic climbing group for teenage girls focused on building self-confidence, cultivating mindfulness, and increasing feelings of empowerment. I incorporate the benefits of climbing into this group therapy program to help participants thrive because I believe that play, exercise, support, and community are vital for mental health and self-confidence. Email me at sienna.f@margintocenter.org to inquire about availability and set up a pre-group assessment if space is available. Currently recruiting teens ages 13-14 and 15-17.
