As a public school teacher and homeschooling parent, I began teaching small groups of homeschooled high school students when my oldest child started high school in 2002. My daughter needed a peer discussion group, so I started a book club with several other homeschoolers and met at a local bookstore twice a month. Fifteen years and hundreds of books later, our little discussion group has transformed into college-prep classes with in-depth analysis of classic literature from around the world. While the literature we read comes from every major literary worldview, we critique each novel through a Christian theistic lens.


Joshua Tree Educational Services, LLC was founded in 2008 to provide college-prep classes for homeschooled high school students. Our objective is simple: We prepare students for the rigor of college-level work. We focus on developing the higher-level critical thinking skills of application, analysis, synthesis, and evaluation.


In addition to our homeschool classes, we tutor public, private, and homeschooled students of all levels in science, mathematics, English, and PSAT/SAT prep.


If you don't see what you're looking for, ask. We may be able to add it for you.
