We had a need for repair on our precision grinding arm. The work Sirois provided was completely successful. We used the arm and had very impressive results . We’re very fortunate to have Sirois on our side!

I wanted to thank you again for taking the time to give a tour of your facility yesterday. It was not only an eye opening experience but very informative and reassuring. Coburn’s trust in Sirois with our parts is well placed. The array of capabilities, the lay out, the readily evident processes, all speak to a well-run operation. It is obvious how you’re is able to achieve the quality and service that you provide. I look forward to visiting again within the year to see the operation in action…

I have dealt with Sirois for the last 6 years and I have found that they have always been able to meet our constant demands for bringing product in early if needed and Sirois is always willing to work with Gerber on cost savings as well as our changing demands.

I have been doing business with Sirois Tool for many years. Two years ago I moved to a major medical manufacturer and brought Sirois along as one of my key vendors. They are now a preferred supplier of tooling and gages for my new company, due to their excellent quality and delivery, and they are also very easy to work with.

Dan Olszewski - Toolroom Supervisor, Synthes

Congratulations!  Not many companies can boast sixty plus years of operation!  In its storied history, all of the previous and current owners and managers, at Sirois, demonstrated both the technical and management skills to be successful. Sirois’ visionaries utilized all of their resources to survive for over six decades. I have been in this industry for over fifty years in various positions as a machinist and engineer.  I have been witness to several economic rise and falls, and the negative impact on the manufacturing community. Kudos to your current staff, each of whom have clearly set the bar for competence and competitiveness.
