Jaime Johnson, Co-Director, Curriculum and Instruction
Jaime is a co-founder of IDEA School and serves as Co-Director, in charge of the pedagogical vision and its implementation. She began her career teaching first grade and kindergarten in Tucson Unified School District where she met the challenges of overflowing classrooms, narrow state standards, and report cards. At TUSD she had an epiphany: To realize their full potential, children must be intrinsically motivated; but to preserve intrinsic motivation, education must be child-led and play-based. Informed and inspired, Jaime moved on to a private preschool, Second Street Children’s School, teaching two-, three-, and four-year-olds. This work, coinciding with the powerful experience of becoming a mother, gave her new insights into how children learn through active, purposeful play.
In 2011, Jaime co-founded Downtown Community School as a child-led, play-based preschool in Barrio Viejo. Her vision there was to support students in their discovery as they grow through the years. It is at Downtown Community School that the seeds of the IDEA School were planted.
Jaime leads her students in explorations of literature, language arts, and history, with an eye toward helping them build their empathy as well as their literacy and critical thinking skills. Jaime’s calling is to engage her students deeply and productively within a safe environment in which they can take healthy risks and be themselves. Jaime provides professional development support to all our collaborators and also works with students needing extra support.
Jaime’s daughter, Tula, attends IDEA School.
David Higuera, Co-Director, Admin and Development
David is a co-founder of IDEA School and serves as Co-Director, primarily responsible for administration, outreach, and development. David began his career in youth development, public education reform and teaching, spent some time in communications, politics, and government, and has come full circle back to education. As a former public school teacher in San Francisco, David appreciates all the potential that public schools hold but also saw firsthand how the rigid, top-down framework in which public school teachers and principals must operate was failing too many students.
David is dedicated to making children’s lives better, believes fiercely in the potential that IDEA School represents, and will gladly work day and night to ensure the school’s success.
David is married to Jesse Evans-Schroeder, a local immigration attorney, and they are the proud parents of 10-year-old IDEA School student Elliot, and his younger brother, Samuel.

Carmen Barnes, Early Childhood Collaborator
I am Carmen Barnes, originally from Arroyo, Puerto Rico. I have a Bachelor Degree in Business
Administration from the Catholic University of Puerto Rico and an Associate Degree from Pima College in
Colorado Springs, Colorado in Early Childhood Education. I have been a resident in beautiful Tucson,
Arizona for the past 5 years and have been working with children ages 3-5 for the past 24 years. Before
becoming a preschool teacher, I worked in the business world in a bank as a teller, and collection and
also worked as an assistant director in two different preschools in the past.
The experiences in Early Childhood programs brought me back to work at St. Mark’s Early Childhood
Center as a STEM teacher. At St. Mark’s, I taught hands-on activities in STEM to children 2 ½ through
Kindergarten. I had been working at St. Mark’s for 5 years; of which, the last 2 years have been as their
official STEM teacher, until recently when I turned in my resignation and accepted the position here at
I also have the privilege of working with the United Way of Southern Arizona as a Community of Practice
Coordinator. In this position, I co-facilitate workshops in STEM for English-speaking cohorts and also
solely facilitate workshops in STEM for the Spanish-speaking teachers. On occasions, I facilitate
workshops for The STEMAZing Project for the Spanish -speaking educators and translate all the
materials for workshops and other projects. From English to Spanish. The STEMAZing Project has been
a tremendous influence in the way I teach and facilitate workshops. For more information on
STEMAZing and my involvement with this wonderful organization, I made a video that is available
through searching for THE STEMAZing Project stories on YOUTUBE.
The STEMAZing Project has invited me twice to attend and teach their workshops to educators in
Tegucigalpa, Honduras at Museo Chiminike. Ninety (90) Pre-K through High School teachers from
Tegucigalpa, Honduras attended our workshops. Working with this incredible group of educators and
DaNel Hogan, director of The STEMAZing Project, has opened many opportunities that enhance my
teaching skills. It has been a continuous adventure to this day.
When I’m not teaching or translating, I like to spend time hiking, listening to music, hanging out with
family and friends, taking pictures of all the desert animals that visit my desert oasis every day.

Debbie Towle, School Counselor, Collaborator Coach
Debbie has had the pleasure and great honor of working in the field of education for more than 30 years. This includes teaching grades K-4, counseling grades K-12, and mentoring new teachers. She has always believed in the “whole child” approach to education which incorporates social and emotional development within the learning climate. She believes in providing opportunities for children to develop qualities such as initiative, integrity, imagination, self-knowledge, and interpersonal skills.
While Debbie took a detour from education to explore the business of overseas travel and whitewater rafting, she ultimately found herself being drawn back to the children, back to teaching. As a result, she returned to school to earn her Master’s in Education and Counseling. Aside from raising and enjoying time with her daughter Liana, now 20, and her husband Steve (both of whom she loves dearly), working with children is where she finds her greatest sense of joy, meaning, and purpose.
After retiring from full-time classroom teaching after the 2017-18 school year, Debbie continues on as our School Counselor and Reading Development Specialist. She is thrilled to be a part of the IDEA school, where students thrive in a community-based environment in which they can expand their creativity, think deeply about topics of interest to them, and be acknowledged for their contributions. Being at IDEA allows Debbie to be part of a system where children and staff are highly valued and cared about deeply.
