Excell Academy for Higher Learning Charter School
Sabrina’s vision for Excell Academy for Higher Learning originated during her childhood years of attending low income public schools and as a licensed elementary teacher in public education witnessing firsthand the inequitable educational services, programs and resources between low income students of color and students from more affluent families. After earning her Master of Arts degree in Curriculum, Instruction & Gifted Education in 1998, Sabrina decided to do something about the passion she had for ensuring a high quality education for low income students of color. With the approval of the Minnesota Department of Education, Sabrina founded Excell Academy for Higher Learning in 1999. Excell Academy began its first year of operation in 2001 with 65 students in grades K-4.
Today, Excell Academy serves over 450 children ages 3½ years through 8th grade and employs over 85 faculty and staff. Sabrina’s leadership has expanded Excell Academy’s services on campus and in the community including full and part time Reading Corps and Senior volunteers, an on-site employee daycare, a 3 ½ year old preschool program, a 4-5 year old Kindergarten Readiness program, three community-based Voluntary Prek programs, an on-site Before and After Care program, on-site Before School tutoring program, After School Athletics and a variety of After School enrichment programs and opportunities.
Sabrina was instrumental in founding and developing the Minnesota Charter Schools Athletic League in 2008 and most recently co-founded the Minnesota Charter Leaders of Color Collaborative. Sabrina is a participant and recipient of the Minnesota Educational Policy Fellowship, the University of St. Thomas Executive Director Leadership Institute, awarded the National Who’s Who in Education Administration two years, Minnesota Principals’ Academy, and a plethora of administration, leadership, and community awards, certifications, and recognitions.
