April Colen
Assistant Principal
(909) 357-5190My name is April Colen and it is my pleasure to introduce myself as your Assistant Principal. I have been an educator for over 20 years and have found my passion in middle school. It is during this time that students develop a sense of identity and autonomy, which makes it crucial that we take care to nurture, support, and challenge them.
I attended Cal State Dominguez Hills where I obtained a Bachelor of Arts degree in Physical Education while being a student-athlete on the womens soccer team. I earned a Teaching Credential and Master of Arts degree in Cross Cultural Teaching from National University. I continued my education in obtaining my Administrative Credential from Cal State Dominguez Hills and a Master of Science degree in Restorative Practices from the International Institute for Restorative Practices. During my educational journey I discovered my passion for supporting and witnessing students achieving at all levels and building relationships with students and families.
My teaching career began in the Los Angeles Unified School °ÅÀÖ¶ÌÊÓƵ where I was a Physical Education teacher for over 13 years. My introduction to the Fontana Unified School °ÅÀÖ¶ÌÊÓƵ came when I joined the Truman family as the Dean of Student Support. I later transitioned to a Climate and Culture Specialist in the Multi-Tiered Systems of Support department. I have been thrilled to rejoin the Truman family as the Assistant Principal!
I am eager to listen and learn from students, families, and staff. Through my educational experiences, I’ve learned that communication with all stakeholders is key to our students’ success. I strive to bring that spirit of collaboration as I build relationships with the entire Truman community.
Please know that my door is always open. I look forward to learning and growing with our amazing students, dedicated staff, and supportive families and community.
