The CIRI Golf Classic is an annual charitable event which originated in 1983 by Peak Oilfield Service Co. colleagues.  It was originally called the Peak Alaska Invitational Golf Tournament.  CIRI took over the planning and coordination of the tournament two years later and raised $2,600 for youth and education. 

For the first 18 years of the tournament, the money raised supported The CIRI Foundation, which awards scholarships and grants to CIRI shareholders and their lineal descendants and supports other cultural endeavors.  When the Foundation reached its endowment goal, the focus of the tournament expanded to benefit other worthy programs focusing on youth and education.
