Welcome to the Andrews Foundation

The Andrews Foundation for Orthodontic Education and Research is an organization dedicated to the advancement of orthodontic research, teaching, and treatment.  It was founded in San Diego, California in 1970 by Dr. Lawrence F. Andrews.  Dr. Andrews is well known for having discovered the Six Keys to Normal (Optimal) Occlusion™ and for inventing the Straight-Wire Appliance.  More recently, efforts at the foundation have resulted in the development of the Six Elements (6E) Orthodontic Philosophy™. Dr. Will A. Andrews is co-director.
