For me, the Presidential Award for Excellence in Mathematics and Science Teaching is an opportunity to be recognized as part of a community of teachers who are dedicated to working and collaborating with one another to make mathematics both meaningful and accessible to all students. It is a reminder that good teaching is not only innovative, but requires reflection, support, and continued growth on the part of the educator. I am greatly honored to be considered for this award.
