Professional statement

Dr. Leslie Peña-Sullivan is a Clinical Social Worker in Mamaroneck who specializes in trauma, as well as anxiety, depression, and coping skills.

As a trauma-informed therapist, Dr. Peña-Sullivan's approach is contingent upon what the client is comfortable disclosing. Clients may prefer to fully disclose their concerns, or they may prefer to focus on developing coping skills to address presenting needs.

Dr. Peña-Sullivan has extensive experience assessing, and treating clients who are experiencing symptoms of Post-Traumatic Stress Disorder (PTSD).  She often uses Dialectical Behavioral Therapy (DBT) to help clients alter behaviors and attitudes, while accepting elements of the world that they cannot control or modify.  Additionally, she also utilizes Trauma-Focused Cognitive Behavioral Therapy (TF-CBT), a cognitive-behavioral treatment approach created to help clients who have undergone a wide array of traumatic experiences.
