Our oldest son started at Circle in Kindergarten and was fortunate enough to continue through graduation; all of our other children have likewise started and are currently at Circle. Circle has been a blessing to our family from the beginning and the partnership of the educators and parents is a Godsend. Likewise, the friendship and encouragement our children have received from the other students are deep and exemplify iron sharpening iron. The ability to have the flexibility of homeschooling coupled with a classroom environment makes them well-rounded and better equipped for college or whatever path God has in store for them.


David Theriault

David began his CCS journey in the fall of 2007 when he, along with his beloved wife Erin and their sons, Jake and Sam, relocated from Southern California to Sanford for David to begin his tenure at Ligonier Ministries as their Video Producer. This move came after almost 20 years in a variety of production roles in Hollywood, all of which groomed him to begin producing educational content for world class bible teachers such as RC Sproul. He continues to serve at Ligonier, now as Senior Manager of Production. In his spare time he can most often be found building sets for Circle Theatre Company, where both of his boys thrived during their years at CCS. David is immensely proud of his extremely talented sons, both of whom graduated from Circle, and is grateful to CCS for playing such an integral role in who they have become professionally and spiritually. He holds a BA in Radio/TV-Film from California State University at Long Beach.

Regarding Circle:

I am truly grateful for the mission of Circle and the unique role it has played in helping parents educate their children - offering students, parents, and teachers the needed support to educate and train their children, with high caliber arts, academics, and athletics in a safe place that embraces God’s word as its guiding rule of faith and practice. It’s a win, win, win!


Tibby Westcott

Tibby is from England and served for over 35 years with Ethnos360 (formerly New
Tribes Mission), twenty-one of those years in Papua New Guinea. As part of the PNG
support team working in crisis management and teaching high school English, she and
her husband helped to spread the Gospel to those who have never had the opportunity
to hear. In 2007 they returned to serve on home staff in Sanford, FL. In 2013, in
addition to her Ethnos360 ministry in MK (missionary kid) care and education and
because of her love of teaching, Tibby joined the Circle team teaching 9th and 10th grade
English and now she teaches DE Composition 1 and 2.

Regarding Circle

Tibby has a deep-seated love for teaching English. With some initial yet understandable
adjustments, she has come to greatly appreciate Circle’s approach to education. Circle provides a unique opportunity to take the word of God as the grid through which
teaching is filtered. Even in an English class, activities and studies can express biblical
wisdom. It is a tremendous privilege to teach in this type of environment and a great joy
to see students grow in both their writing abilities and their walk with the Lord.
