“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


Hello! My foundation in working with clients and families comes from attachment-focused approaches DDP, AEDP that focus on how our relationships have impacted our capacities to feel and express emotion and cope with the joys and challenges of life. I am passionate about helping people, families, and organizations understand their stories of adaptation in order to form stronger connections within themselves and with others. I am energized by 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.

-Parent-Child Attachment Related Concerns
-Organizational Consultation


I first began my journey with Dyadic Developmental Psychotherapy (DDP in 2007. When I teach or supervise other professionals, I emphasize creating an atmosphere of emotional safety that celebrates the diversity of identities of who I teach and cultures where I teach, so that trainees can feel affirmed to play, explore and soar in their professional development. I have provided workshops and trainings in the United States, Finland, Greece, the Czech Republic, United Kingdom, North Macedonia, Kenya, New Zealand and Australia and has observed that what is unifying across all these countries is people’s remarkable dedication and tenacity in trying to connect with vulnerable children, and of course the unending awe sparked by resiliency.
