Background: I have an undergraduate degree in Physics from MSU and an Ed.M. from Temple U. After serving in the US Air Force, briefly as a student pilot and long term as a "Weapons Controller" (armed aircraft traffic controller), I moved to Philadelphia. I taught Physics there for ten years and home schooled our three children, my wife bearing most of the burden. We moved to Grand Rapids in 1988 to be near our extended families. My career also included engineering work for a defense contractor and for the Naval Air Development Center, both in Philadelphia. Back in G.R., I worked in sales and served as AWANA Commander at Calvary Church. My wife and I now attend First RPC of G.R. My hobbies include amateur astronomy and eschatology.

Hannah DeJonge

Position: Teacher—Conversational Spanish, Spanish I, Spanish II, Introduction to Graphic Arts, Yearbook
Contact Information:
Background:  I am excited to be teaching both Spanish and Art at GRACE! I was homeschooled for 6 years from 1st-6th grade and attended Coopersville Public Schools from 7th-12th grade. Upon graduation, I attended Elmhurst College near Chicago and received my B.A. in Psychology (Pre-Occupational Therapy), Art, and Spanish this past spring. My goal, Lord willing, is to earn my doctorate in Occupational Therapy within the next few years!

I have studied the Spanish language for nearly 10 years and have traveled abroad to Spain to study traditional Spanish culture. I truly enjoy being able to connect with native speakers! A memorable moment was sharing the gospel in Spanish to a college student in Miami with Cru (Campus Crusades for Christ). I believe that learning a language is a privilege that we are able to use to further Christ’s Kingdom!

During high school, I was able to attend Kendall College of Art & Design for two years and fell in love with artistic expression. I have had my work featured at various shows and received numerous awards. Art is a wonderful way to use our talents to worship our Maker!

While in college, I was involved in Cru, and am still actively involved with their Bible studies and discipleship program. In my free time I enjoy traveling the country to see my friends, being outside, and spending time with family.


Miss LexAnn DeWeerd

Position: Teacher—The Art of Photography

Contact Information:
Background: I am honored to be teaching at GRACE, as I actually graduated from GRACE as a high schooler in 2001. I enjoyed taking my first art classes at GRACE, where I learned how much I loved to oil paint. Since then, I have grown as an artist, using all kinds of media. Through the years, I have sold dozens of oil paintings, participated in Artprize, and have been commissioned on many occasions to create art for various clients. Also, I have a huge passion for art photography, black and white film photography. I studied clinical nutrition and herbalism at Blue Heron Academy of the Healing Arts and Sciences, where I received my certification to be a Master Herbalist.
In contrast, my background involved mostly sports and fitness, as I was a figure skater and coached children and adults in figure skating, and due to an injury in 2004, I believe God redirected my life-path. It was then that I truly delved into the fine arts in a new way, and I knew God was working in my life to do more with me than just athleticism. I live in Grand Rapids during the school year, and for the last 5 summers, I have enjoyed living and working at a Christian Conference Center on Lake Michigan in Norton Shores, Mich. My life go-to verse has become Ecclesiastes 9:10 "Whatever your hand finds to do, do it with all your might"... I have learned to be "all there where ever I am" and no matter how menial or grand the task, do it all to the glory of God, my Creator!

Position: Teacher—Traveling Through U.S. History I, Writing Based on Fables, Myths, and Fairy Tales, Cities and Landmarks Aound the World
Contact Information:
Background:  I was raised in Byron Center Michigan, attended South Christian High School and graduated from Calvin College with a double major in Social Work and Elementary Education. After teaching at Dutton Christian School for 5 years, God took me on an adventure of teaching overseas. I accepted a position at a wonderful Christian school in Istanbul, Turkey where I was blessed to teach for 6 years. During this time I met my husband, Rob, who was also working there. We were married in Istanbul and returned to the USA after the birth of our first daughter. My husband took a youth pastor position in Tennessee and our son was born in our town near Nashville. We decided that being close to family was a priority and moved back to my home, Michigan (Rob is from Houston) in 2005. After all of that traveling we ended up buying a home next door to my parents' home in Byron Center and the kids run back and forth daily. It's been a wonderful landing spot for our family of now 5. Our youngest daughter was born in 2009.  I have homeschooled our children with much thankfulness since kindergarten.
I cannot wait to meet your children and teach them about God's great world!!!

Mrs. Lynnae Murray

Position: Teacher—Chemistry, Anatomy and Physiology
Contact Information: (616) 350-0052;
Background: I graduated from both Cornerstone University and Kuyper College in 2018 with a Bachelor of Science in Bible and Theology and a Bachelor of Arts in Secondary Education: Integrated Science Comprehensive (a fancy way of saying that I am certified to teach any type of science to middle-school/high-school-aged students). My passion is teaching students about the greatness of God made evident in His creation and studied in the subjects of science. I have loved watching both high school and college students progress from dreading/disliking science to enjoying it! I also love finding creative ways to help students learn, since each student has been gifted in different areas, and processes/retains information differently. Besides teaching, I also work for the Institute for Reformed Biblical Counseling, which seeks to train Christians to counsel in the light of God’s Truth from a Reformed perspective. Prior to this, I had taught 8th grade Gems at my church for 5+ years, cared for adults with various disabilities at Olivia’s Gift for 2 years, studied/cared for plants at a greenhouse for 6+ years, and lab-assisted for various college professors for 2 years. My favorite past-times include fishing, exploring, gift-giving, thrifting, drinking coffee, tutoring, and spending time with my husband, Allan. I’m looking forward to my first year of teaching at GRACE. I’m hoping and praying that my students will learn that Chemistry is fun (yes, fun!), and that it reveals much about the complexity and majesty of the Creator.

Dr. Christina (Tia) Parks

Position:  Teacher—Biology, Comparative Anatomy with Dissection
Contact Information:
Background: Hello, my name is Christina Parks. I received my Ph.D. in Cellular and Molecular Biology from University of Michigan in 1999. During my years in graduate school, I realized that I had a passion for education and working with young people. At that time, I decided that I would rather pursue a career in education rather than continue on in research. After a short stint editing High School Biology textbooks in Texas, I got married and was coaxed back to Michigan. In 2003, I went back to school and received my Teaching Certification from Grand Valley University (2004). I taught a variety of Biology and Chemistry courses at Hesperia High School for 5 years while enjoying gardening, horse-back riding and skydiving with my husband. In 2009, we adopted a brother-sister pair from Ethiopia and I came home to care for and homeschool them. Although I still grow a large garden, my children are my primary “hobby” now! My son Sam is now 18 and is preparing to go to college. Wow! Where did the time go? Over the last 11 years, our family has been challenged by my daughter Tess’ special needs and blessed by her sweet, ebullient personality. She is now 11 years old and is attending public school. She currently communicates using sign language. As a teacher, I am extremely passionate about opening the eyes of my students to the intricacy and majesty of God’s creation. Hopefully, with a little encouragement, your student will be as excited about learning science as I am about teaching it.

Christina Stephenson

Position:  Teacher—Art I, Art II,  Art III, Art IV, Bible Art Journaling, Mixed Media Art
Contact Information:
Background:  I am excited to be teaching at Grace this year and am looking forward to being a part of this wonderful community! I am married to my husband, Duane of 7 years, and together we have two girls, ages 7 and 5.  Before feeling called to pursue teaching, I completed a BFA degree in Illustration from Grand Valley State University. And though teaching is clearly where I have been called in this season of life, it is a dream of mine to publish my first children's book someday.  I have taught art to a wide- range of students with varying abilities, including Kindergarten through 8th grade at Excel Charter Academy.  This experience sharpened me, but more importantly, revealed what was vitally missing in my work, the ability to proclaim and share the word of God... in all circumstances!  My greatest desire is for students to gain confidence in expressing themselves through art and to share the deep joy of exalting and connecting to our Creator through artmaking! I can't wait to explore watercolor, drawing, journaling and so much more with students.
