Stuart Demmy
Executive Director: Loomis Gateway Academy
Certified Educational Remediation Specialist, Certified Dyslexia Screener, Utilizes Making Math Real Strategies, Waldorf Class Teacher
Stuart worked for many years as a Waldorf Class Teacher in schools in Oregon and California where he gained extensive experience in teaching various subjects to children in Grades 1 – 8.   A common experience for him during these years was encountering children still unable to read well after years of instruction.  What was wrong?  The schools did not have an answer to this question. Fortunately, research by his wife Tesa led them both to the Barton Reading System, an Orton Gillingham approach to teaching reading and spelling.  After experimenting with the system, Stuart became convinced of its efficacy.  
Stuart has been a beloved math teacher for decades.  He now finds the Making Math Real approach to teaching math as beneficial to his students struggling with math as the Orton Gillingham approach to teaching reading is to his students struggling with reading.

   Melissa Emerzian

    Making Math Real Teacher


      After graduating from Harvard with a BA in Biological Anthropology, Melissa worked          under a grant from NASA developing and teaching science lesson plans to elementary        school teachers and students.  This experience was the catalyst that led her away from        medical school and into the world of education.  She worked in the Governor's office of        the Secretary of Education and implemented the California Academic and Volunteer            Mentoring Program throughout schools in California.  From there, she took a position        lobbying for public education associations.

     Motherhood inspired her to say home with her children and take an active role in their       education, which eventually led straight to Loomis Gateway Academy.  Her son and             daughter entered the program 8 years ago, thus beginning her own association with,           and love for, LGA.  Seeing firsthand the success of the Barton Method and the Making        Math Real program with her children, she wanted to help give other children the same        opportunities.  She returns to LGA as a math teacher and has undertaken her training        with Stuart Demmy.  She looks forward to working with your children, to help them            gain a sense of accomplishment in learning.

Andrea Sivillo

Afterschool Tutoring Program Director

After leaving the business world to stay home with her children, Andrea discovered and cultivated a passion for language and literacy.  Having gained many years of practical experience teaching her own dyslexic children and tutoring in a well-known homeschool program, she is dedicated to providing help and encouragement to other parents as they navigate their children's learning difficulties.

Seeing firsthand the difference that the Barton Reading and Spelling System makes in the lives of children with dyslexia, she is a devoted follower of the Barton method.  Having guided her children through educational challenges, she has developed the patience, empathy, and spirit of encouragement that children with dyslexia and those who love them need.  She is enthusiastically supportive of Loomis Gateway Academy's mission and finds immense joy in helping children with dyslexia thrive educationally.
