We love St. Mark! You truly feel like you are part of a family. The curriculum is engaging, challenging and fun. My children have all gone here and they are excelling now as teenagers because of the foundation that was set here in their early years. The teachers are highly educated, enthusiastic and above all love the children as their own. The fact that they instill a love for Christ in all they do is just another reason on top of their amazing academic program.

This school is amazing! My daughter was placed in advanced math in first grade and was able to read fluently. Their program is so advancing but at the same time well-tailored to meet every individual child's needs. We highly recommend this school to anyone looking for a wonderful community to join.
