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 online educational website English Grammar 101, which Marvin and Bret co-created back in the year 2000.

With a few shortcomings in the original material for English Grammar 101, the company enlisted help from Kitty Nash, a middle school language arts teacher. Kitty rewrote the entire series and this new version was launched in 2015 along with a more feature-rich learning management system.

The company continues to work on the materials and software in order to improve the instruction, readability, and usability. Minor improvements are released throughout the year. Major improvements are released each July.

In 2019, the company partnered with Clever to provide single-sign-on and automated rostering—highly requested and powerful features. The partnership with Clever also permitted a new architecture for the application that greatly improved privacy and security.
