About Us

The COS intervention and the graphic designed around it are intended to help caregivers increase their awareness of their children’s needs and whether their own responses meet those needs. With increased awareness parents can expand their moment-to-moment parenting choices where needed. In this shift from mind-blindness to seeing what is hidden in plain sight lies the potential to break the stranglehold of problematic attachment patterns, passed from one generation to the next, that can compromise healthy relationships throughout a child’s lifespan.

Glen Cooper, Kent Hoffman, and Bert Powell have been working together since 1983, designing and implementing treatment protocols for individuals, couples, and families. Our work is based upon an interface of attachment theory, object relations theory, and family systems theory. Thank you for choosing to look further into our work on the Circle of Security.

Circle of Security® Reviews

The Circle of Security Parenting® DVD is an outstanding contribution and a “must see” for parents of young children. Focusing on how parent/child relationships can be strengthened, this unique approach teaches parents, and those helping them, new ways to understand children’s needs and behavior. It also offers effective ways to respond to these needs and behaviors. I have found it invaluable in my own  work with parents of young children.”

“Circle of Security provides therapists with a near complete model for parent/child psychotherapy. COS is theoretically grounded, evidence-based, and uniquely understandable and appealing to parents.  It is rare to find such a sophisticated clinical model with such wide applicability.  I would urge all parent education programs to add the Circle DVD to their tool kit.”

“The clinically effective Circle of Security® model is solidly based on the most recent advances in developmental neuroscience and attachment theory.”

“The Circle of Security® is circling the globe as an intervention to help parents raise their children with love, warmth, and emotional intelligence. The four researcher/clinicians who invented this important new and effective program are themselves filled with these positive traits and a huge dose of common sense and devotion to the well-being of others. These innovators have created a readily accessible and engaging approach to helping parents, young and old, to connect with their infants and toddlers in ways that break the old, destructive patterns of parenting that so often have been learned by difficult childhood experiences in the past. Cited from England to India, the Circle of Security™ offers new hope for making the hard earned wisdom of attachment research available to clinicians helping parents heal old wounds and building new options for the next generation.”
