Retirement Announcement from Lynette and Allen Nadeau

After much reflection, we are announcing our retirement from Southington Tool & Mfg. Corp. (STMC).

For Lynette, it has been an incredible journey that began when she was just 16 years old, and over the past 40+ years, she has had the privilege of growing with the company and the community it’s built. Allen joined STMC in 1997, and together, we’ve shared the pleasure of working alongside so many dedicated colleagues, valued customers, and trusted suppliers. Through trade organizations, we've even formed lasting friendships with people from our respected competitors – an experience we will always cherish.

Retirement, while a dream for many, is bittersweet. While we look forward to the new adventure that lies ahead, it’s hard to say goodbye to the people who have made this experience so meaningful. We’ve been fortunate to work in an environment where dedication, camaraderie, and hard work were central to everything we did.

We are deeply grateful for the support we’ve received from all who have been part of our journey, and we want to thank each and every one of you – whether coworkers, customers, suppliers, or friends – for the incredible relationships we’ve built over the years.

As we embark on this next chapter, we will carry with us fond memories of our time at STMC. Thank you again for everything.

With warmest regards,
Lynette & Allen

Partial Change in Ownership at Southington Tool & Mfg. Corp.

We are pleased to announce a significant milestone at Southington Tool & Mfg. Corp. Anthony Califano has acquired the shares and building interest of three retiring owners, marking a new chapter in our company's journey. Anthony, a longstanding member of our team with a robust background in manufacturing, now assumes the role of principal and president at STMC.

Before this acquisition, Anthony distinguished himself as the power press department supervisor and a skilled journeyman tool maker. His expertise and dedication to excellence have been pivotal in our operations over the years. Alongside Anthony, remaining partners Kris Lipinski and Peter Martin will continue to play integral roles in advancing the capabilities of STMC.

Together, we are committed to upholding our core values and honoring the legacy of our founder, Ed Kalat. This transition ensures continuity while bringing fresh perspectives and leadership to propel Southington Tool & Mfg. Corp. into a successful future.
