About Us
Complexus, formerly known as F&F Machine Specialties, is a proven leader in the manufacturing of complex orthopedic instruments. Its reputation is built on making the most difficult instruments – those with multiple components and assemblies and tight tolerances – in a timely, cost-efficient manner.
Our team has more than 100 years of combined manufacturing experience and technical knowledge.
Complexus stems from humble beginnings. It has evolved from a small tool and die shop that opened in 1968 and has since grown from its basement origin in Mishawaka, Indiana. Today, Complexus finds home in modern, state-of-the-art facilities, specializing in high quality, precision products serving the Orthopedic Device and Implant Industry.
Now under the leadership of Michael Behrens, the company is constantly improving function, time-to-market, and cost. Behrens ensures the company’s core values remain intact by keeping Complexus small enough to know every detail, but big enough to continue delivering sophisticated manufacturing solutions needed in an ever-changing global marketplace.
Complexus uses state-of-the art equipment to manufacture components with tight tolerances and complex geometry. The company also does all its own in-house welding and finishing for the instruments it manufactures.
After an expansion in 2013 doubled the size of headquarters in Mishawaka IN, Complexus pursued a second site in 2021. This development proves Complexus can expand with current and new customers for years to come by operating out of facilities located in Mishawaka and Plymouth, Indiana.
