Teaching Tools for the Connected Classroom

About Us

Cingletree Learning, LLC is a privately-held company located in Laguna Niguel, California. The company was founded in 2009 to assume operations from LearnDesign.com, a collaboration between the late Marvin VanHorne and his son Bret. Cingletree Learning continues to operate the successful online educational series English Grammar 101, which Marvin and Bret co-created back in the year 2000. Recently, we have launched a completely rewritten version of the series along with a more feature-rich learning management system.
