I look forward to working with the staff of Warren High School in the administration of all our instructional programs, and achieve our vision.

Warren students will have the opportunities to discover their unique abilities to maximize their full potential to pursue a successful journey after high school.

General information and expectations: I am pro-active for all students. High school can be great for some and a challenge for others. My daily mind-set is to point each student in the right direction. I expect students to ask me for assistance and to be respectful to their teachers and fellow classmates. I believe discipline should be designed to improve future behavior, rather than punish what has already been done.

About me...I have worked for the Northside School District since 1997, spending time as a coach, middle school administrator, central office administrator and now here at Warren. I am proud to work with such a great staff and in such a supportive community.
