“I think the big shift occurs when you can start seeing yourself as adaptive rather than pathological. The cascading impact on increased self-compassion and the broader lens with which you see the world that unfurls from that change is a privilege to bare witness to.”
Courtney Rennicke


Dr. Rennicke specializes in attachment-focused approaches (DDP, AEDP) to working with adults, children and families. She is passionate about helping people and families understand their stories in order to form stronger connections within themselves and with others. Dr. Rennicke also enjoys teaching other mental health professionals, parents and organizations about how attachment based principles can improve the quality of their lives and the culture of their groups.


–    Anxiety, Depression and Bipolar Disorders

–    Post-Adoption Issues and Parent-Child Attachment Related Concerns

–    Children and Adolescents with ADHD and Disruptive Behaviors

–    Mental Health Issues Related to Medical Conditions

–    Posttraumatic Stress Disorder (PTSD), Trauma, and Bereavement


Dr. Rennicke first began her journey with Dyadic Developmental Psychotherapy (DDP) over 10 years ago.
She has been fortunate to be directly supervised by Dan Hughes, Ph.D., the founder of DDP, in learning how to both practice and teach this rich model for working with children and families.

Dr. Rennicke emphasizes creating an atmosphere of emotional safety where learning one on one in supervision or amongst a group can feel grounded in order to play, explore and soar in your professional development. Dr. Rennicke has provided workshops and trainings in the United States, Finland, the Czech Republic, United Kingdom, Kenya, New Zealand and Australia and has observed that what is unifying across all these places is people’s remarkable dedication and tenacity in trying to connect with vulnerable children, and of course the unending awe sparked by resiliency.
