executive director


krista k. gauthier

Krista first conceived of SDSquared when, as a parent of a dyslexic child, she noticed that the access she was able to provide her daughter in both remediation and STEM enrichment was denied to so many for a variety of reasons. 

Krista has over 10 years of experience in education, both asteacher and as a researcher in educational theory and curriculum.  Most recently, she gained valuable nonprofit development experience as a development director at a Northern Virginia private school.  Krista has taken those two professional experiences and used them to found and build this one of kind program for children with dyslexia.

barbara dalmut

I come from a family dedicated to education and community service. I loved teaching elementary and middle school, and am currently serving as Principal of St. Bernadette Catholic School in Springfield, VA.  I am also an Adjunct Professor in the Catholic School Leadership Graduate Program at Marymount University in Arlington, VA.

Schools can be vibrant places that shape young hearts and minds, but they can’t do everything for everyone. Families who are challenged with their children’s special learning needs deserve our support. I am proud to be a part of this innovative program.  It is my hope that SDSquared will provide the opportunity for these brilliant young people to thrive!
