Marissa Keilson LCSW-C works with teens and adults of all ages. With a warm and non-judgmental perspective, her calming presence and years of experience helps individuals heal, grow and develop into their best and strongest selves. 

Among her many talents is the ability to listen carefully and kindly, offering specific suggestions, ideas and support to help the individuals she serves improve in all areas of their lives. A natural teacher, she treats those she works with as partners in learning and growing, and makes sure they understand what tools they can use for self improvement and healing. Marissa has worked with individuals around issues of trauma, from sexual assault victims to veterans, and individuals who have suffered loss or life events that left them feeling they had nowhere to turn. Compassionate and affirming, Marissa values above all else the power of relationships and connection, and infuses her role as therapist with these principles.

Marissa uses a blend of cognitive behavioral and psychodynamic techniques in her work with her clients. Her expertise includes the neurobiology of trauma, anxiety and stress; understanding how the brain works and how to help it heal emotionally. She is trained in the use of cognitive behavioral therapy for the treatment of insomnia (CBT-I). With an undergraduate degree in art and an awareness of the myriad ways we connect to ourselves and our emotions through creative expression, Marissa brings the use of art therapy and other expressive modalities into her work consistently both for individuals and in the groups she facilitates.

At Sequence Marissa is also the Assistant Director of the SEQUENCE INSTITUTE for Learning and Education, and together with our Executive Director Kathleen Landers LCSW-C, she develops curriculum and organizes workshops and training for our range of clients in the areas of Wellness, Career Development, Therapy, and Parenting, as well as offering continuing education training for other mental health and affiliated professionals.
