Meet Thomas C. Rector

Founder, Accrescent Institute


As a father of five, adoptive parent, a foster care mentor and trainer, CASA, and board member for child advocacy organizations, Thomas C. Rector brings a unique perspective to child advocacy and parenting.

He is a CEO, national speaker and presenter on BioSocial Cognition theory, and founder of Accrescent Institute, as well as the former Executive Director for CASA of Del Norte and Vice President of the NFPA Board of Directors.

For 30 years, Thomas C. Rector has studied widely in the fields of biology, genetics, neuroscience, philosophy, and psychology. The BioSocial Cognition Behavioral Model, a paradigm-shifting theory and methodology for parenting and working with others, is a direct result of his interdisciplinary study and experience as a parent, child advocate, and professional.

Thomas C. Rector’s specific experience with adoption and children in foster care adds further insight into how biology, neurology, and environment impact memory formation and behavior among children who have grown up in the foster care system and/or have been adopted.

For 20 years, he has trained others how to use the principles of BioSocial Cognition to further relationship and positively impact memory formation and behavioral responses when working with adults and children from all walks of life.

He has been married for 53 years, has five children -- three birth children and two children chosen through adoption -- and eight grandchildren.
