David Grosskopf

Grosskopf, David

English Language Arts Teacher

I've been teaching English at Roosevelt since 1997, only a few years after I graduated from there. English is the best subject to teach and take because it plays in psychology, morality, social critique, art, creativity and personal expression, philosophy and history, and because it demands a deeply personal engagement and humility.

Katinas, Matthew

Physical Education

I have been a teacher in the Seattle School District for 28 years. I have served as a substitute teacher, an elementary physical education teacher, athletic director, and for 19 of the past 21 years, a physical education/health teacher here at Roosevelt. My vision is to instill within each student the intrinsic value and enjoyment that comes from leading an active and healthy lifestyle and my mission is to enhance my students school day. This is supported by core values to know my students on an individual basis, to help make them feel valued, safe, and included as part of the R.H.S. community, and to give them the knowledge and skills to be fit for life – physically, mentally, and socially, capable to meet life’s challenges.
