Kenny received his Bachelors and Masters degrees in Social Work from the Jane Addams College of Social Work, University of Illinois, Chicago, in 1985. He has worked as a child and family clinician across the entire continuum of therapeutic services for children, including inpatient psychiatric, day treatment and outpatient therapy for both corporate as well as private, non-profit settings.

Kenny began full-time private practice in 1993, joining a group of clinicians in Tucson, Arizona who specialize in the treatment of early neglect and abuse, Esperero Family Center. In 1994 and 1996 he came with children from his practice to what was then the Attachment Center of Evergreen for two-week intensives in their model. He first began presenting workshops as well as offering trainings and consultation locally to agencies in 1995 in the "Evergreen Model" as it was most commonly referred to at the time.

In 1999 Kenny attended a workshop by Holly van Gulden and had his professional world turned upside down from her ideas about understanding these children from an Infant-Toddler developmental perspective. He immersed himself in the study of Infant-Toddler Mental Health theory and practice and first grasped the power and relevance of this body of work for helping older children. Between 2000 and 2005 he worked for two national continuing education companies, traveling the country and presenting a one day workshop on Attachment Disorder to over 3000 people. From this exposure came requests for more extensive trainings from agencies and communities across the country.

In 2005 the last seed was sown for the comprehensive model for resolving attachment trauma in children that he has chosen to call Developmental Attachment-Based Psychotherapy.© (DAP) At the ATTACh conference that year a workshop presented by Robert Marvin, Ph.D introduced him to the work of the Circle of Security Project. From this model have come the tools to complete a continuum of interventions for both children and caregivers that are rooted completely in both child and adult attachment research and theory. This model focuses on teaching both children and parents the "attachment skills" necessary to first create a trusting and secure emotional base for the child, and then to resolve trauma, once relationship skills of safety and connection are "inside" the child.

Kenny currently maintains a limited private practice in Tucson, Arizona and is now focused on providing training, education and support in this model for parents, therapists, and agencies around the country and the world. His trainings succeed in making simple the complex nature of this work, while offering profound and lasting change for children and families. He continues the study of the emerging interface between attachment theory, trauma and neuroscience in an effort to grow and refine this revolutionary model of work.
