Sarah Decker – Discovery Center


Classes Taught: Junior High

Bio: I finished my undergraduate studies at Calvin College in May, 1991, receiving a Bachelor of Science degree.   That fall, I was excited to start teaching at Heritage Christian School as 8th grade homeroom, teaching 7th and 9th grade science along with 8th grade math.   After some years of night school and summer school, I received a Master of Education degree in 1998 from Grand Valley State University.   I continued to teach as a full classroom teacher at Heritage until 1999.  After a few years away, it was a blessing to return to the teaching staff in 2004 as a teacher in the Academic Support program, working specifically with junior high students.
