Educator | Author of #TechWithHeart | TED-Ed Talker | Keynote Speaker | #Edtech & Innovative Teaching Consultant

I have been in education for over 15 years. I have worked as a math teacher and director of educational technology. In my math teaching, I have taught courses ranging from Algebra 1 through AP Calculus AB (13 years of experience teaching AP Calc). I have taught students face-to-face, using a flipped classroom model, and in a purely online format. I have been creating instructional videos for students and teachers since 2010 and my videos have over 3 million views on YouTube.

I am passionate about discovering and sharing innovative ways to leverage technology to cultivate deeper compassion in the classroom and provide each learner the optimal platform to express their ideas in a format that best fits their learning style. I aim to equip teachers with ideas and tech tools to create more inclusive, equitable, and empowering classrooms for every student to find their voice, build their confidence, and take ownership of their learning. In my math teaching, I continue to enjoy improving my flipped and online teaching models and tutoring students virtually and through video.
