Our Staff


Krista K. Gauthier - Executive Director/President

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 as a teacher 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.


Joyce Maryanopolis - Tutoring Director/At-Large Board Member

Joyce is a certified elementary and special education teacher.  She has been teaching for 22 years with a focus on supporting children with dyslexia.  She first became interested in educating children with dyslexia while watching a family struggle with reading.  Joyce earned her certification to teach Alphabetic Phonics, an Orton-Gillingham approach to teaching reading and spelling, from Teachers College at Columbia University in 1998.  She soon thereafter began a successful private practice tutoring children with dyslexia.  Joyce is excited about being apart of Sliding Doors and  its ability to reach more students. She is eager to share her knowledge and years of experience with other adults who are passionate about serving students with dyslexia.


Barbara Dalmut - Board Of Directors

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

Barbara knows that 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. She is proud to be a part of this innovative program.  It is her hope that SDSquared will provide the opportunity for these brilliant young people to thrive!
