Greg Irwin, LCPC

Greg IrwinGreg Irwin is a Licensed Clinical Professional Counselor. Greg graduated from the University of Illinois Champaign-Urbana in 2008 with a B.S. in Psychology, and from the University of Illinois Springfield in 2015 with a Masters in Human Development Counseling.

Working as a residential counselor at Cunningham Children’s Home, Greg came to know “youth with severe behavioral problems” as being severely traumatized kids with few, if any, healthy relationships, and very poor emotional regulation. He ended up spending five years at Cunningham Children’s Home, where he learned a great deal about life and people. Perhaps most importantly for therapy/counseling, Greg learned that kids can make great progress emotionally, behaviorally, psychologically, and in regards to developing healthy relationships. However, if the child is placed back into the situation that created these problems, the problems will reappear rather quickly. This concept led Greg to family therapy. Greg has focused on and utilized the theoretical orientations of John Gottman, Sue Johnson, and Theraplay. Throughout his professional career, Greg has worked with clients as young as four and as “young” as 70. Greg has worked with individuals, couples, and families. He has worked in offices, homes, residential settings, schools, and parks. The individuals he has worked with come from a variety and wide range of socioeconomic backgrounds, developmental stages, cognitive abilities, and trauma. Greg loves people and believes in the influence of attachment, safety, security, parents, and families.

In his down time, Greg enjoys spending time with his family, sports, games, traveling, and being with friends.
