Mr. Andrew Riffel

Mr Riffel is in his third year teaching mathematics at Lincoln High School. Born in Los Angeles, he’s had the privilege of studying in Argentina (his parents’ home country) and teaching in Kerala, India before moving to Portland. Mr Riffel also loves to sing and is a member of both the Oregon Repertory Singers and the Trinity Episcopal Cathedral Chamber Singers. Mr Riffel is only available on B Days at Lincoln this year because he gets to switch roles during the week and sit as a student at Portland State University. He’s honored to be working with such an excellent mathematics team at Lincoln and teach such great students!
