\n\t\t\t\t\tMichelle Schecter, LMSW<\/strong> – Staff Therapist<\/em>\n

\nMichelle Schecter, LMSW earned her Master in Social Work (MSW) from NYU Silver School of Social Work. She previously earned her JD from NYU School of Law. Michelle brings many years of social and emotional intelligence from her first career as a lawyer representing domestic violence survivors. Her experience serving this population gave her many opportunities to witness the transformative power of therapy. This background inspired Michelle to take a special interest in PTSD. Michelle\u2019s interests and experience working with trauma have also heightened the importance of providing a therapeutic space where clients feel safe to explore a wide range of human experiences of loneliness, social anxiety, mistrust, violation, panic, anxiety, depression, grief, anger and shame. Michelle has witnessed the extraordinary resilience that each of us contain. She builds on that resilience with both traditional psychodynamic and modern third generation CBT skills to begin the work of generating positive and lasting change.\n

\nHer training at a NYC psychoanalytic institute, and in private practice as a psychotherapist, has given Michelle the opportunity to work with clients facing myriad of life stressors; medical illness, psychiatric diagnosis (social phobia, Panic, OCD, PTSD, major depression), substance use, and also to relational issues, ie., divorce, LGBTQ+ traumas\/stressors, coming out, death of a loved one, relationship conflict. In addition to her experience with adults, Michelle has also worked in an inner city agency with teens and young adults struggling with acute anxiety and depression.\n

\nHer professional journey as a therapist has also inspired a keen interest in third generation CBT and ACT (Acceptance and Commitment Therapy). Michelle has been honing these modern approaches to therapy via ongoing training with a multitude of trainers, workshops, conferences, case conferences, and a rich array of senior supervisors and trainers. Michelle\u2019s primary goal is to provide a nurturing environment free of judgment, and rooted in empathy, where the client feels heard and empowered. She believes learning to listen non-judgmentally to each other and to ourselves and learning to listen with acceptance and compassion, are key ACT and CBT skills which can help us to navigate even the biggest challenges in our relationships within ourselves.\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
