Michelle Shreve

Assistant Principal

Greetings Excelsior Family,

My name is Michelle Shreve, and I am honored and excited to serve as your assistant principal for the Victorville campus. My journey began as a long-term sub, before being hired full-time as an Education Specialist and facilitator in September of 2010. My experiences with Excelsior include serving as a senior facilitator, club advisor, class advisor, coach and assistant coach for multiple sports, yearbook advisor, photo advisor, ASB advisor, and graduation coordinator.

My motto is to never stop learning and I hope to encourage and support students and staff to do the same. After earning two Associates degrees from Victor Valley College, I was able to continue my education at Azusa Pacific University earning a Bachelor’s Degree in Human Development with an emphasis in English, then a multiple teaching credential, mild/moderate and moderate/severe education specialist credentials with my Master’s Degree in Education at Chapman/Brandman University.

Recently, I have earned a certificate in Applied Behavior Analysis, completed courses for a single subject English credential, and earned my Preliminary Administrative Services Credential. In the near future, I plan to clear my Administrative Services Credential while beginning a Doctorate program. With this experience, I look forward to serving Excelsior students, staff, and families while continuing to learn and grow.

Kindest Regards,

Mrs. Michelle Shreve


Matt Diniz

Assistant Principal

I am excited to be at Excelsior’s Victorville campus serving the families of the high desert area and supporting the incredible staff at the site and the amazing work they do in providing students with quality education.  I am an alumnus of Azusa Pacific University where I earned my Master of Arts degree in Educational Leadership and an alumnus of Chapman University where I earned my Bachelor of Arts degree in Social Science.  I began my career in education in 2007 working as a teacher for the Snowline Unified School District, teaching students in grades 6-8 at a middle school and later students grades 9-12 at a continuation high school.  In 2010 I was fortunate to have the opportunity to join the team at Excelsior’s Victorville campus.  During my time here I have served students and families in the capacities of Facilitator/Teacher for grades 7-11 and as an Assistant Principal.  My titles and job duties have changed throughout my time as an educator but what has not is my uncompromising view that all students can learn, given a positive learning atmosphere and the support of their parents/guardians and teachers.
