About Us


MESA was founded and has been in operation since June 2012.  It is a private, non-profit organization that It is governed by a 9-member volunteer Board of Directors.  The Board meets on a monthly basis.  MESA has lesson programs in both towns of Big Piney and Pinedale in Sublette County, Wyoming.  Participants ride on a weekly basis during the lesson sessions.

MESA relies heavily on private donations & community grants to support its program.  We feel strongly that it is important to offer our riding lessons to participants free of charge.  We have been able to continue to offer these lessons for the past 6 years and wish to continue to do so without imposing any economic burden on the families of our MESA riders.
