About Me

I have worked for more than 30 years with individuals and families who have experienced or are currently struggling with trauma, substance use and/or relationship issues. I received my family therapy training at the Philadelphia Child and Family Training Center which grew from the Philadelphia Child Guidance Center, one of the birth places of family therapy. I currently practice in a private setting in Delaware, but have many years of experience working in the public sector with individuals and families who are challenged by severe and persistent mental illness and/or substance use disorders, many of whom have significant co-occurring trauma.
