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.

Richard Katz

Katz, Richard

Social Studies Teacher

People say I am very funny, open minded, generous, gregarious, love laughing, and have the energy of a 16 year old. I enjoy discovering new things about myself, others, and the world. I also love helping out whenever there is a need where I can. I have been in Seattle since 1990 and love the fact that the city nourishes talent and incubates people as they grow as I was able to until they discover their gift or path in life. Mine turned out to be a passion for teaching Geography to young people. Looking forward to my 27th year teaching with a new challenge of AP Government and AP Comparative Government.
