Kim Lynn Lehnert, PhD, Psychologist in Mount Sinai
In my work as a clinical psychologist, I believe the connection between therapist and client to be the most important agent of change. Healing happens best in the context of a warm, collaborative and supportive relationship. When an individual is going through a difficult time or life experience, he or she often feels small, disconnected and incapable of making positive changes on his or her own. In safe connection, it becomes possible for the individual to feel empowered, connected and more flexible and capable of making the decisions and behavioral changes necessary to heal and/or move forward.
My clinical experience has been with adolescents, adults and the elderly. I have worked in a broad range of settings and my specialization in trauma, substance abuse, and chronic suicidality has enhanced my ability to work with people presenting with more common issues of depression, anxiety and interpersonal difficulties.
I believe it is important to help clients identify and articulate their life goals and to work towards achieving them together. I tend to be solution-focused rather than problem-focused. Specifically, I am intensively trained in and have been a national trainer in Dialectical Behavior Therapy(DBT).
