GSDMC Executive Board
Jason Slowbe, President
I have taught high school math since 2004 – my first 3 years were in Cleveland, OH, then I moved to Southern California and taught at Escondido High School, San Marcos High School, and currently at Great Oak High School. Whether it's professional development, curricular revisions, or my wicked addictions to GeoGebra, Excel, and programming, my passion is teaching high school mathematics. I have worked with NCTM in various roles, including Illuminations, the Reasoning and Sense Making Task Library, Regional and Annual program committees, and as a task group leader for NCTM’s High School Summer Institutes. I work with the CMC-S Conference Committee for their Palm Springs conference. With GSDMC, I have been the Secretary and also Webmaster since 2010, and now welcome the opportunity to lead GSDMC forward as President.

Teachers don’t teach a subject, we teach a child. This quote continues to drive my professional career, understanding that relationships are at the center of our work. For the past 18 years, I have been blessed with the ability to walk alongside athletes, students, and staff throughout San Diego Unified. Serving in various roles as teacher, coach, ASB Advisor, Athletic Director, Vice Principal, and most recently District Office support, I have reached the understanding that the work done collectively will far surpass any work done in isolation. Teaching high school mathematics in the inner-city of San Diego, brings to mind the most fond highlights of my career. Appreciating the beauty of mathematics, while understanding that each and every child brings their own experiences to engage in rich, powerful conversation, inspires my work. Structured collaboration to dive deeper and make meaning is where, I believe, true learning occurs. I am looking forward to learning together with all of the bright minds that make up the Greater San Diego Area.
Sean Nank, Secretary
The GSDMC brings resources to students, parents, and educators in our local communities that are essential for connections, collaboration, and the betterment of mathematics education. We stand on a precipice of change with our transition to Common Core. This transition makes GSDMC more important than ever before. I look forward to the opportunity as secretary to bring my experiences and resources to our wonderful organization. I will use my experience as a Presidential Awards for Excellence in Mathematics and Science Teaching (PAEMST) recipient, author, researcher, consultant, and ICME-12 appointed mathematics assessment expert to continue the great work at the GSDMC.
