Erik Therwanger, President

Born in New York and raised in Southern California, Erik enlisted in the United States Marine Corps and served our nation from 1987-1991. After being honorably discharged, Erik attended Orange Coast College and the University of Southern California with the dreams of becoming a filmmaker. Life had different plans and Erik left the entertainment industry to be his wife’s caregiver during her first bout with cancer.

After four years in the financial services industry, Erik returned to the entertainment industry and worked his way from entry level scheduler to vice president as he helped the company develop a leadership team, sales system, and a plan that would elevate their results to over 300% sales growth. He founded Think GREAT in 2008 and draws from his experiences as a U.S. Marine, executive business leader, sales professional, and entrepreneur to help organizations achieve new levels of success. He now delivers dynamic keynote speeches and presentations, based on the contents of his book series, The Think GREAT Collection.

Erik has provided motivational and inspirational training sessions and workshops for the spouses of the United States Marines Corps and the Air National Guard through their Yellow Ribbon Reintegration Program. Erik has long-held the desire to create a foundation that allowed him to achieve his desire to “enrich the lives of military families.” The Think GREAT Foundation is the culmination of years of working with military families and understanding their unique challenges and needs.

Erik now lives in Minnesota with his family.
