Hello and welcome! My name is Zachary K. Hubbard and teaching is my passion! Prior to 2013, I taught in elementary schools, teen homeless shelters and group homes. It was in that year I discovered Gematria, and since then it has been my mission to help this knowledge reach the world. Thank you for helping me in that effort!
