Barbara Strachan

AATN Secretary

Barb recently returned to Catholic Charities Community Services as the Manger of DIGNITY Services/Diversion Programs. These programs address both the supply and demand sides of sex trafficking and sexual exploitation in AZ.

Prior to returning to the Diversion Programs, she was the Senior Associate of the Social Impact Programs for the Girl Scouts AZ Cactus-Pine Council for more than 16 years. She was responsible for reaching girls in some of the challenging areas of our communities including group homes, girls whose parents are/were incarcerated, justice involved girls, girls in refugee programs and several Boys and Girls Clubs, community centers and schools where more than 95% of the children are on free and reduced lunch. Girls in these programs were given the same opportunities as girls in traditional volunteer led troops; the only difference is there are a cadre of part time staff, interns, and volunteers to create the consistent safe place and safe space for girls to thrive.

Barb has come full circle.  She was the second graduate of the DIGNITY Residential Program in 2000. In 2001 she went to work for Catholic Charities DIGNITY Programs as an intake specialist, then a case manager, and finally the supervisor. The Diversion Program is for people who are involved in the sex industry. Approximately 69% of the clients are between the ages of 18-28 years old. Much of what Barb learned at the Girl Scouts applies to working with this younger population. She is excited to return to Catholic Charities DIGNITY Programs.
