 Assistant Principal elina martinez

Greetings! I am Elina Medina-Martinez, a Denver native with strong ties to the San Luis Valley and El Paso, Texas. I am the proud mother of three adult young men a little one ladybug named Victoria who is 8 years. I hold a Colorado license in Cosmetology, which came from my first experience with education as a young single mother when I desperately needed a way to self-sufficiency. I hold a BA in Law and Society, a Masters Degree in Curriculum and Instruction with an emphasis on Language Acquisition, and completed the Ritchie Program for School Leaders all through the University of Denver. I first found my calling to serve Denver students through an alternative pathway into teaching, the Denver Teacher Residency. My teaching career began in Montebello serving in a Spanish classroom where I literally fell in love with the idea that I could become a gardener of sorts, planting seeds of knowledge, watering minds, and nurturing a safe place for my garden to bloom. I believe that we are not defined by our circumstances, we are defined by the hard work and effort we put into our education, that allows for what is inevitable- personal growth and limitless possibilities. I am so humbled to be part of the Manual community where I continue to serve Denver students as an Assistant Principal and Director of the Med School at Manual. We have an exciting announcement to kick off the school-year coming soon! I am so excited to be part of the Leadership team and community of Manual and look forward to getting to know all of you.
