Inspiring Confidence. Empowering Success. Behind the success of each Denver Academy student is a team of uniquely qualified expert faculty always willing to go above and beyond. Before ever stepping into a classroom, they receive extensive specialized training in a range of learning styles and the Denver Academy approach to teaching and learning. All teachers participate in a minimum of 100 hours of professional development each year and attend various conferences and workshops. At Denver Academy, teachers are empowered with the freedom and flexibility to deliver curriculum in ways that effectively engage, challenge, and inspire each student to reach their full potential. Faculty Photos View All DA Alumnus At DA, I was surrounded by amazing teachers who wanted to see every one of their students succeed. Teachers come to Denver Academy because they are creative, energetic and believe in the potential of every child. They stay because they value the supportive team environment and know they are making a real impact in the lives of their students. Many of our teachers are regarded as the "best-in-class" by their peers and are frequently asked to present at conferences, seminars, and workshops. But just as important as their training and credentials is the creativity they bring to their classrooms. At Denver Academy, we empower educators and staff of all backgrounds and identities to achieve their personal and professional goals. We are committed to creating and retaining an inclusive and multicultural community and value the authentic contributions of all our employees.
