History -  Tendon Manufacturing Inc.

Cleveland, Ohio Machine Shop

Tendon Manufacturing was founded in July of 1988 by Michael Gordon Sr. and Greg Tench. Greg and Mike worked together at Warner and Swasey until 1987 and while working together, they formed what would become, a lifelong friendship. Greg knew the manufacturing side of the metal fabrication business and Mike knew how to handle the fiscal side of the metal fabrication business. As Greg recalls, “To run a successful business together for almost 30 years, never get into an argument and still be best friends, that is the definition of a partnership.” The company started as a general machine shop with just 6 employees. Sheet metal fabrication was added shortly after inception, and now in 2016, Tendon employs over 75 highly skilled metal fabricators in our 50,000 square foot facility located in Warrensville Heights, Ohio. Tendon is unique in the metal fabrication & manufacturing industry because of the full service nature of the company. Whether it is laser cutting parts, welding, machining, forming, assembling, powder coating, prototype designing or 3D printing, Tendon offers everything in between for their clients and operates 24/7.

Growth of Tendon Manufacturing Inc.

Since 1988, Tendon has grown from being a small machine shop in Cleveland, Ohio to a national company conducting business across the world. Today, you can find Tendon manufactured parts in big box stores, hospitals, lighting stores, marinas, office buildings, professional stadiums, tanning salons, vehicles and many other places. Tendon Manufacturing has grown year over year since 1988 due to our constant effort in cross-training employees, expanding our sheet metal fabrication capabilities and by investing in our customers. At Tendon, we find great satisfaction in seeing our customers succeed and we continue to grow with each of our clients.

Tendon Manufacturing Inc.

ISO 9001:2008 Certified


Tendon Manufacturing (Cleveland, Ohio) has been awarded a 2017 Top Workplaces honor by The Plain Dealer. The Top Workplaces lists are based solely on the results of an employee feedback survey administered by WorkplaceDynamics, LLC, a leading research firm that specializes in organizational health and workplace improvement. Several aspects of workplace culture were measured, including Alignment, Execution, and Connection, just to name a few.


“The Top Workplaces award is not a popularity contest. And oftentimes, people assume it’s all about fancy perks and benefits.” says Doug Claffey, CEO of WorkplaceDynamics. “But to be a Top Workplace, organizations must meet our strict standards for organizational health. And who better to ask about work life than the people who live the culture every day—the employees. Time and time again, our research has proven that what’s most important to them is a strong belief in where the organization is headed, how it’s going to get there, and the feeling that everyone is in it together. Claffey adds, “Without this sense of connection, an organization doesn’t have a shot at being named a Top Workplace.”
