Cathi Cohen, a Licensed Clinical Social Worker and Certified Group Psychotherapist, has worked with children, adolescents, and adults in a clinical setting since 1984. Early in her career as a social worker, Cathi recognized the power of treating relationship problems through group therapy. It was this interest and expertise that led her to create the Stepping Stones Social Skills Group Therapy Program in 1990.

Cathi is the author of Raise Your Child’s Social IQ: Stepping Stones to People Skills for Kids, and has become a leading expert in the field of social skills training with children. She has since then completed two more books, Stepping Stones to Building Friendships: A Guide for Camp Counselors, and Outnumbered, Not Outsmarted: An A to Z Guide for Working with Kids and Teens in Groups. In addition to writing numerous articles and conducting regular workshops for parents, educators, and mental health professionals, Cathi has appeared on radio and television programs about the mental health needs of children and their families.
