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.

Kelly Ensink – Discovery Center


Classes Taught:  Kindergarten, Second and Third Grades, and Discovery Center (mainly reading, grades K-3, supporting the classrooms, and teaching alternative curriculum when needed)

Bio: I graduated from Calvin College with a degree in Special Education. After graduating, I filled a long term subbing position for a semester at Ken O Sha, an early childhood center. I then got a job teaching 2nd grade at Hudsonville Christian School. After 2 years, I began teaching part time at Heritage Christian School, helping out with Special Ed. students and in the Discovery Center. I have been teaching at Heritage since 2004.

I am married to Scott Ensink, who is a graduate of Heritage. We have 2 girls, both at Covenant Chr. High School. We enjoy vacationing and spending time outdoors together.

Mike Noorman – Educational Support Director


Bio: I graduated from Calvin College in 2002 with a Bachelors Degree in Elementary Education with minors in Science and Social Studies and taught sixth grade for 11 years at Heritage.  During that time, I returned to Calvin College and graduated in 2010 with a Masters Degree in Learning Disabilities.  In 2012, I was hired as the Educational Support Director to oversee the Discovery Center and Academic Support Programs.  I also coach boys basketball at Heritage, and boys and girls varsity soccer at Covenant Christian High School.

Teaching at Heritage Christian School is a privilege and a blessing for me.  It is my prayer that the work I do as a teacher and coach can be used for His glory.  I get to work in a community of believers who are committed to the Lord and love His covenant children.  My wife and I are seeing how important Christian education is from a parent’s perspective.  Because of the unquestionable impact that a teacher has on the children in their class, I am grateful for our Protestant Reformed Christian schools and teachers.

I enjoy interacting with young people at our schools and churches.  The expressions of faith and love for God that they show are encouraging to my family and me.  In our free time, our family loves spending our time outside playing soccer, basketball, whiffle ball, swimming, and riding bikes around the neighborhood.  We also love to read, play games, and hang out with family and friends.
