Former and current owners Lou Griffith (L) and Jeff Penterson (R)
History
RK Griffith & Associates was founded in 1971 by Robert “Bob” Griffith, who had served as Vice President of Sales and later as President at Riley Stoker Corporation in Worcester, MA. Bob’s father Louis E. Griffith II started with Riley in 1923 and served as President from 1962-1964.
Louis E. Griffith III ("Lou") joined RK Griffith in 1976, serving as President until 2012 and retiring in 2014. In June 2012, the company’s ownership was transitioned to Jeff Penterson, who had joined RK Griffith in 2009 after previously working for seven years at Babcock Power (Riley).
Today, the original Riley roots are reflected in both our product lines and our focus: utility and industrial steam generation equipment for both electric power and process needs.
