    Started teaching at Bullis in 2011.

    My teaching is student-centered, focused on achievement, active and engaging to meet the needs of each child. My teaching style is warm yet firm with high expectations for all students.

    I love Bullis because each student, faculty and staff member is unique and special while at the same time Bullis is a place where everyone belongs and fits as one community. The sense of self as a part that fits into a community is valued.

    Started teaching at Bullis in 2004.

    I finished medical school as a general practitioner, but I was more interested in teaching science rather than practicing medicine. Teaching is exciting, unpredictable and challenging.

    I believe students need to feel comfortable to learn and ask questions. I use humor to get their attention and technology to relay what they need to learn. We work on simulations, hands-on labs, class discussions, contests, blogs, movie clips and small group projects in the class. Science is meant to be exciting.

    Started teaching at Bullis in 2008.

    My philosophy is that if I do not have the passion to teach, it is impossible for my students to have the passion to learn. I work hard to engage my students in learning so they will love what they learn. I think that if what they need to learn is not significant to them, they do not learn at all.

    Started teaching at Bullis in 2006.

    I became a teacher because I have an intense passion for the Latin language, Roman history, and Greco-Roman culture and wanted to find an outlet for that passion.  The Latin language and Greco-Roman culture have had such a profound effect on our lives as Americans, and I love helping students make that realization.  I cannot imagine doing anything else!

    I believe very strongly in making the subject matter of my classes accessible to all my students. Latin can be challenging, but anyone can master it. Often, students come into my class intimidated by the idea of taking what they perceive is a very difficult language. I make it clear very quickly that they will succeed and that I expect a lot from them!

    In order to help our class material to come to life for my students, I have assigned them projects such as acting out scenes from Roman history and creating short films of Greco-Roman myths. When students are able to act out the material we are learning for others, it helps them to enjoy and care about the material even more.
