Getting to know Bryn O Donnell

Copilot said: Bryn O Donnell helps children, adolescents, teens, adults, and seniors across New York navigate complex emotional and life challenges through compassionate, evidence-based therapy at LifeStance Health. She provides individual, group, couples, and family therapy, supporting clients in managing anxiety, trauma, and substance use concerns while building practical coping skills and emotional resilience. Bryn’s clinical approach is collaborative and adaptable, drawing from Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and Acceptance and Commitment Therapy (ACT) to meet each client’s unique needs. She works with individuals experiencing PTSD and trauma, generalized anxiety, and alcohol or drug use issues, and offers additional support for related mental health concerns. Her care emphasizes insight, behavioral change, and strengthening relationships, helping clients make meaningful, sustainable progress. She is particularly dedicated to working with individuals navigating high-acuity or complex circumstances, including those recently discharged from psychiatric hospitalization, participating in court-ordered treatment, or managing active legal matters. Bryn provides steady, structured support during these critical periods, helping clients stabilize, rebuild confidence, and work toward improved functioning and independence. Bryn has experience working with diverse populations, including members of the LGBTQ+ community, military service members and veterans, and individuals with autism spectrum disorders. She is attentive to the broader systems impacting her clients’ lives, including family dynamics, school concerns, and major life transitions. She earned her degrees from Fordham University and Boston University and has been practicing since 2015. Outside of her clinical work, Bryn enjoys creative expression through writing poetry and novels, painting, and music.
