Great Valley Aikido
472 Acorn Lane
Downingtown, PA 19335

Great Valley Aikido is a direct descendant of Aikido Suimei, founded by Garrett Fuller Sensei (sandan) in Phoenixville, PA in June, 2003. In the spring of 2008, Garrett Sensei accepted a job in San Diego. The students of Suimei decided to continue training as a group, and began running the dojo as a student-run organization. After a brief hiatus following Garrett Sensei's departure, the dojo resumed training in July, 2008. The dojo name became Great Valley Aikido at that time.

On January 1, 2009, the dojo moved to Downingtown and began sharing space with Metzler's Gymnastics.

The head instructor is Dave Lyons, nidan.
