SHARE was established in 1998 by local families who knew home educating would take a village. That village has grown to now offer a Christ-centered program designed to support, challenge, and engage home educated children and their families. We begin each day with a time of devotion and prayer before starting our studies, and continue to emphasize a Christian worldview throughout the day. SHARE meets every Tuesday in Columbia, from 8:30 until 2:15.  If you are interested in the courses we offer click here.

Hello and welcome to our SHARE Homeschool Tutorial website! As one of the founding members of SHARE, I have worn many hats throughout SHARE’s 27-year existence. I have homeschooled my four children with the help of SHARE, and am now a grandparent to two current SHARE students. I have also served as a SHARE helper and as a teacher for the past eleven years. And now I am taking on the role of your new SHARE director. I pray that my lengthy experiences as a SHARE parent, teacher, and veteran homeschooler will serve you well as director. Homeschooling is quite a commitment and SHARE was such a valuable source of support and encouragement to me and I want it to be the same for you. It is my desire for SHARE to continue to provide our students with an environment where they are encouraged and challenged to be their best selves, where they experience kindness and Christian fellowship, and where they can have fun, hands-on learning and make lasting and nurturing friendships. Over the years our size has greatly increased, the class offerings have changed a bit, and we’ve gained and lost teachers as their life stages progressed, but the dedication and love poured into our students remain our solid foundation. At SHARE, we seek to not only partner with you in the academics of homeschooling, but also come alongside you as friends and mentors. Chances are, whatever your situation or question, one of our staff members has dealt with it in some form or fashion. Although we might not always provide you an answer, we will willingly share our experiences and will ALWAYS lend you a loving and listening ear!

I'm a mom of three former SHARE students and have been teaching art at SHARE for 10 years. I love introducing young artists to the elements of art and different art mediums. In my spare time I love to travel with my family, go on hikes, and try out new coffee shops with friends!

I am the mother of two current SHARE students and in my sixth year of homeschooling. I was a former kindergarten and 5th grade math teacher prior to homeschooling and am so excited to be back in a classroom setting in my first year on the SHARE staff. Outside of SHARE, I own a small commercial cleaning company. I love my chickens (all 40 of them), reading, coffee, and hanging out at the pool with my family.

I spent six years teaching preschool and kindergarten before joining the SHARE staff in 2024. I love to encourage students to be curious about the world around them and to have a love for learning. When not teaching, I am chasing my one-year-old son and spending time with my husband.

I have been a part of the SHARE staff for 11 years, serving as helper and  the K-2nd math enrichment teacher for the past four years. It is my goal to help your kids see that math can be fun, even if it is not their favorite subject, as it was mine. I have three adult children, all graduates of SHARE, and after a 23-year homeschool journey, I graduated my last this spring. I enjoy spending time with my family, drinking dark coffee, crocheting, and reading a good book.
