Mary L Deitch, JD, PsyD, Psychologist in Woodlyn
I have worked with problematic sexual behaviors and physician boundary issues for over a decade and have a passion for helping clients find answers. Often the behavior is not the issue but the client's reaction to the behavior or there are underlying reasons for why they are engaging in maladaptive behaviors. Each client is unique and the issue is often about unmet needs for nurturing, control, power, love and connection. Helping clients find the answers, their resiliency, and improve their healthy sexuality is an amazing part of the work that we do together.
I specialize in problematic sexual behaviors (sexual addiction, paraphilia, sexual offending), physicians with boundary issues or disruptive behaviors, assessment and education.
I am the former Director of an internationally recognized treatment facility for sexual addiction and trauma. I worked personally with over a thousand clients and conducted hundreds of assessments. I am also a licensed attorney which lends a unique view of forensic circumstances that can be helpful to clients.
