Leon Gellert
Psy.D. Clinical Psychotherapist
I am a clinical psychologist working with adolescents and adults in individual psychotherapy. I work with individuals on a range of presenting concerns including depression, anxiety, substance use, feeling “stuck” or “lost,” history of trauma, relationship or family distress, identity-development, as well as difficulty with change and transitions. An important aspect of my clinical work is to be a warm and curious partner that fosters a space where individuals can feel comfortable enough to engage with uncomfortable issues.
About Me
Education and Experience

​
I am a licensed clinical psychologist (PS018824) who received a doctoral degree in Clinical Psychology from Yeshiva University—Ferkauf Graduate School of Psychology of Albert Einstein College of Medicine (APA Accredited). I also earned a Master’s degree in Forensic Psychology from John Jay College of Criminal Justice and my Bachelor’s degree from Trinity College.
​
In addition to my private practice, I am a therapist at Swarthmore College's Counseling and Psychological Services where I provide individual psychotherapy for students. In my career I have worked at University Counseling Centers including NYU, Drexel, and SJU, and also with Veterans at the Brooklyn VA. Through these experiences I have worked with individuals from varied backgrounds who have come to work on a range of issues ranging from managing the difficulties of growing independence to the significant impacts of past traumatic experiences. My clinical internship was completed at the VA NY Harbor Healthcare System, Brooklyn Campus (APA Accredited) and focused on the provision of psychotherapy to veterans who were managing concerns around substance use.
