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.

SHARE Director

Dawn Costello
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 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. I have three adult children, all former SHARE students, and after 23-years of homeschooling, I graduated my last this spring. I enjoy spending time with my family, drinking dark coffee, crocheting, and reading a good book.
