Peggy Pace graduated from the University of Washington in 1969 with a Bachelor of Science degree in Chemistry. She later returned to school to study Psychology, and in 1985 received her MA degree in Counseling Psychology.

In 2003 she wrote and published the first edition of “Lifespan Integration: Connecting Ego States through Time”. From 2005 until her retirement in 2016, Pace traveled and taught Lifespan Integration to therapists in the United States, Canada, France, Spain, Sweden, Switzerland, the United Kingdom, and Russia.
