Lisa Foreman

Head of School

Mrs. Foreman joined BASIS Charter Schools as the Director of Student Affairs at BASIS Peoria Primary. Being a part of the BASIS Flagstaff family as the Head of School, and among the ponderosa pines, is a homecoming for her. Mrs. Foreman was born and raised in upstate New York before moving to Arizona to attend Northern Arizona University. She holds a BA in Business Administration Marketing, which led her to work in product development and international marketing. She realized her passion for helping children learn and grow when she started her own family, so she returned to school to pursue a BA in Education and an MA in Curriculum & Instruction. Prior to joining BASIS Charter Schools, she served as a K–8 classroom teacher; Regional Trainer; Curriculum and Assessment Developer; Gifted Trainer; and as Curriculum, Instruction, and Intervention Specialist. She spent ten years mentoring new Mandarin teachers in a Mandarin immersion school and traveled to China with a Chinese Bridge Delegation to learn and share about international education. She holds endorsements in Elementary Education, Structured English Immersion, and Early Childhood Education.

Matthew Gibson

Matthew Gibson

Head of Operations

Matthew Gibson joined BASIS Flagstaff in the 2016-17 school year as the 6th-8th grade Chemistry Teacher. Mr. Gibson enjoyed teaching middle school chemistry, but when an opportunity opened up for him to use his extensive repair knowledge to benefit all students and faculty of the BASIS Flagstaff campus, he accepted the role of Facilities Coordinator. Now, as the Head of Operations, Mr. Gibson will miss all the daily “hands on” jobs, but knows that he can leave an even bigger mark by expanding on the positive influence that BASIS Flagstaff has in the surrounding community.

Mr. Gibson attended Northern Arizona University where he completed his undergraduate and graduate degrees in Chemistry. It was his goal to be an educator, but knew that real life experience in application of concepts and knowledge is critical in being able to educate others. He used his extensive experience with chemical instrumentation and electrical/mechanical engineering ability to become a supervisor and maintenance manager for a local forensic toxicology company before returning to education and, ultimately, becoming a member of the BASIS Flagstaff community.

Tori Terpening

Director of Academic Programs

Coming from a family of educators, Mrs. Terpening always knew she would end up working in a school. She moved to Flagstaff to attend Northern Arizona University and graduated magna cum laude with a BA in Spanish and minors in both French and Latin American Studies. She joined BASIS Flagstaff in 2014 to teach Spanish for grades 7–12. As BASIS Flagstaff grew, she joined the Auxiliary Programs team, and then the Academics team as Curriculum Coordinator. She has learned a great deal about what goes on in a K–12 school and is excited to continue working with students and families as Director of Academic Programs.
