It is with great pleasure that we announce Sierra Engineering Group’s transition from a sole proprietorship to a professional corporation, effective June 1, 2009.
While our personnel and virtually all daily activities remain unchanged, we have updated our Federal Tax ID, so if you need an updated W9 form, please contact Irma with the subject heading "W9 Request." (Please allow one week for processing.)
