A few words from Grindal regarding recent changes

It is with deep regret that we announce the passing of our president and founder, Norman L. Spooner in April of 2012. Norman established the Grindal Company in 1965 with the goal of being the best grinding specialist in the industry. We at Grindal continue to build on Norman's foundation of providing top quality and service to our customers. As the first chapter of Grindal closes, we turn to the next with the same dedicated staff that has provided you with our services to the present day.


I have worked for and with my father Norman for many years, serving the company most recently in the position of Secretary/Treasurer. As the newly appointed President and owner of Grindal, I am committed to maintaining the quality and standards set forth by my father and we at Grindal look forward to serving you in the future.


Yours truly.
Jan Spooner
