About Sierra Freeman, LMSW
Sierra Freeman is an associate therapist at Brightline’s Brooklyn clinic, providing care under the supervision of Sylvia Ryszewska, PhD. Her background includes experience as both a social worker and educator; she has supported kids, teens, and parents across school settings, community mental health agencies, and within forensic social work.
Sierra has helped families navigate parenting challenges, ADHD, anxiety, depression, emotional regulation difficulties, peer conflict, and academic or organizational struggles. She has particular experience working with neurodivergent youth, especially those with ADHD, and supporting parents as they foster independence, build routines, and strengthen executive functioning and emotional regulation skills.
Sierra’s therapeutic approach draws from cognitive behavioral therapy (CBT), parent management training (PMT), solution-focused interventions, trauma-informed care, and dialectical behavior therapy (DBT) skills. Her background in education enables her to collaborate effectively with school teams, interpret data, and develop school-related support and intervention plans.
She is passionate about making therapy accessible, strengths-based, and empowering, especially for kids who may not always feel understood in larger systems. What excites Sierra the most is witnessing meaningful, everyday progress: a child using a coping skill independently, a parent gaining confidence, or a young person recognizing their neurodivergence as a source of strength.

What is an associate therapist?
Associate therapists have earned their master’s degree in social work, psychology, marriage and family therapy, or counseling. They have a limited license to practice under supervision, and are completing their supervised hours at Brightline to work toward their independent licensure. That means that all of the work they do with your family will be supervised by one of Brightline’s licensed providers. Their supervising provider will review all session notes, care plans, conversations, and recommendations to ensure the approach to your child’s treatment is aligned with our standards of providing high-quality, safe, and ethical care. Supervising provider names can be found on each associate therapist provider page on our website; the associate therapist will also share who their supervisor is at the start of care.
