eTutor was conceived by Dr. Martha Angulo, an educator with more than 30 years of experience as a teacher, principal and school district superintendent.  Dr. Angulo first began developing eTutor in 1997 to apply her rich experience in education to the newly discovered power of the internet.  The online school now rests on a foundation over a decade in the making.  eTutor began in Chicago, Illinois and moved its main office to Boulder, Colorado in 2008.  A satellite office is maintained in Park Ridge, Illinois.

eTutor is the premier product of Knowledge Headquarters, Inc. a privately held Illinois corporation.  Knowledge HQ is a certified WBE (Women Business Enterprise) and is registered with the Better Business Bureau of Colorado.
