While being a part of the rugby team, we served the community in various ways, mentoring kids being one of those.

It was this love for education which has kept me in the field for over 15 years. I have spent 8 years as a teacher, 3 as an Assistant Principal, 1 as an Associate Principal, and 3 years as a Principal. It was also during these times that I gained my Masters and Doctoral Degree, as well as my Superintendent Certification.

I enjoy hanging out with my boys, joining in CrossFit workouts with my Misfit family, being with family, and doing educational research. I look forward to seeing the success our students, teachers, and staff will have starting this year. I know that our current leadership and the plans being set forth, we are going to be a great success, and most of all create success for all students.
