Family Therapist

After receiving her Bachelor of Arts in Sociology from the University of Cincinnati in 1980, Carol MacIsaac obtained a Master of Arts in Counseling from Chapman University in California. Since joining Sierra Tucson in 1991, she has served many roles, including clinical supervisor, children’s program coordinator in the Family Program, and case manager.

“The Family Program is reflective of the Sierra Tucson Model® in that it is a systemic approach,” Carol says. “The whole family heals; it’s not just about one person.”

The time spent at Sierra Tucson was the true beginning of my journey. Not only did I overcome my addictions, but I began to focus on the root causes that created my compulsions. I understand myself so much better now.
