Camp Griffin Director, Academic Aide, Certified Lifeguard

Hailing from upstate NY I have found my home at Green Fields. As the Academic Coach I have the opportunity to both support and challenge students. I work with classrooms, individuals and small groups in all grades, K-12. Green Fields allows me to provide the support, personalization and time for an education that addresses a child's individualized level of need within the group. Every day I am excited to come to work in such a balanced and challenging environment for our children.

Teacher, LeadYou Leadership Camp

Originally from Flagstaff Arizona, I graduated with a B.S. in Elementary Education from Northern Arizona University.  I taught first grade in the Cherry Creek School District in Denver, Colorado, first and second grades in the Marana School District in Tucson, and kindergarten and fifth grades at Green Fields.  During my daughter's’ preschool years, I was an active parent volunteer and board member at Tucson Community School.  When my oldest daughter joined the Green Fields community, I began work in the kindergarten classroom, first as the art teacher, followed by two years as an assistant, joining the staff full time in 2014.  My volunteer roles at Green Fields include being a member of the Board of Trustees as well as President of the Parents Association.  I am very passionate about education and enjoy learning about learning and teaching.  When I’m not creating in my classroom, I’m thinking about creating what’s next!  I also enjoy activities that involve creative expression, moving and being outdoors and reading.

Camp Teacher

I’m enthusiastic about creating and innovating and have led many class projects including the induction of our 2nd grade class pets, two rats named Diana and Selina. My love and passion for teaching stems from my personal experience with a mentor, this is what drives me to be a mentor for others. When I’m not in the classroom or crafting for class at home, you’ll find me hanging out with my two cats and two dogs or playing RPG my husband Seth.





Dr. Lesa Randall

Camp Teacher

I believe in teaching young children foreign languages the same way they learned their first language – by letting them experience words and phrases and make connections as they play games, sing songs and do other activities that keep them physically active and completely engaged. This is known as “whole language” teaching. The process is so fluid and fun that the students fall in love with foreign language. I earned my master’s and doctorate degrees in French literature from the University of Arizona. Here at Green Fields I have worn a variety of instructional and administrative hats. I currently teach Spanish and French to grades K-5, as well as high school French IV, AP and an independent study on French cinema.  I'm a Montana native and have studied and taught numerous times in France. I enjoy cooking, reading, traveling and hiking with family. I have two daughters, Jasmine and Rose, who currently attend Green Fields.
