Joel Krieg, LICSW, CGP

Joel Krieg, is a social worker with a private practice in Cambridge. He has worked in various settings - inpatient, partial hospitalization programs, and community mental health centers. Joel was introduced to NSGP in June 2010 after reaching out for help with the PHP groups he was tasked to lead at the time - he was struggling. The very next day he biked to Simmons College to attend NSGP's Annual Conference. It was a day/weekend that greatly changed his personal and professional trajectory. Through supervision, being in groups, observing groups, and learning about groups, he went from dreading them to absolutely loving them. He's been involved in NSGP from the get-go, chairing or co-chairing the Breakfast Club, Training, and Scholarship Committees and presenting and leading/co-leading in several ways. Joel has been less active in recent years due to starting a family and covid, and he can't wait to continue the work of helping NSGP be a rich, vibrant community that is welcoming to people of all identities.
