Guides, Assistants,
and Administration
Amanda Fernandes

Primary Casita Guide

Amanda Fernandes is a graduate of Thomas Aquinas College and holds an MA in English from the University of Dallas. After working with young children for several years, she discovered Montessori and has never looked back. She completed her AMI primary diploma in 2018 and is currently training as a Level 1 Catechist with Catechesis of the Good Shepherd.

Mike Gleason

Lower Elementary Guide

After graduating from the University of Dallas in 1988 (in Classics, Anc. Greek), Mike taught English at Northlake College and taught middle & high-school Algebra, Geography, and Literature at Oakhill Academy (under the same roof as the Highlands School back then), where he assisted the Principal in Year 2. It was there that he saw Grace's Montessori classroom operating so beautifully. He took his AMI Montessori Elementary Training in 1995 immediately after his AMI Montessori Primary Training in 1994, all right after marrying Grace on St. Joseph's Day in 1993. They have been blessed with 7 surviving children (including Hanna, who worked at St. Francis Montessori before they did, and Susan who assists with the Catechesis of the Good Shepherd in Lander, WY). Raising their own and coaching plenty of others in baseball has made Mike appreciate those Montessori principles beyond the classroom. 


Teaching for St. Alcuin (now just “Alcuin”) Montessori in Dallas, for their own Holy Childhood Montessori at St. Mary the Virgin in Arlington, for St. Helena Montessori in the Napa Valley, and for two public Montessori schools in Milwaukee has amounted to 27 years of Montessori work at all levels from Primary to Upper Elementary (25 in the classroom, mostly Lower Elementary). The other two years saw him working on digital, Montessori-color-coded, Greek sentence-diagrams for (a Classics app to run on Firefox, Chrome, and Safari). The last 15 years have also afforded more education, including the NAMTA Montessori Adolescent Orientation course and a Masters in Educational Leadership from Milwaukee School of Engineering. And yet for Mike nothing has been as instructive as parenting, which allows him to see eye-to-eye with his students' first educators
