Blessed are all who fear the Lord, who walk in His ways. You will eat the fruit of your labor; blessings and prosperity will be yours. Your wife will be like a fruitful vine within your house; your sons will be like olive shoots around your table. Thus is the man blessed who fears the Lord. May the Lord bless you from Zion all the days of your life; may you see the prosperity of Jerusalem, and may you live to see your children’s children.

2007 - 2008

With a humble beginning reminiscent of how the most iconic American companies got their start, in May 2007 Bob and Heidi Devroy turned their home garage into a work space and Prosper-Tech was born. Even in in the midst of a recession, their hard-work, ingenuity, and expertise prevailed, allowing the company to prosper even in extremely difficult economic times. In the span of just one year, Prosper-Tech had hired two skilled employees and outgrew the garage, sending the company in search of a larger work space to handle its rapidly expanding business.

2008 - 2013

During the next five-year span, Prosper-Tech found its stride within the manufacturing world. Operating out of a 3,600 square foot facility in Lenox, MI, the company hired two more skilled workers and purchased a new Haas CNC VM-2 Vertical Machining Center. It's growing production abilities and work force was followed by an increased workload and expanding number of satisfied customers. In May of 2013, the company once again found itself outgrowing its surroundings and had to move to a larger facility where it could meet its growing demand.

2013 - Present

In 2013, Prosper-Tech renovated and moved into a 10,000 square foot state-of-the-art facility in the Devroy’s hometown of Richmond, MI. By 2015, they added two Haas CNC Machining Centers, a VM-3 & UMC-750, plus an additional Charmilles Roboform 40 to its growing list of equipment. That same year, the company became ISO 9001 certified to ensure its products and services could meet higher quality standards.

In 2018 after the company realized substantial growth in its Production Machining Department, it added a Hexagon 4.5.4 SF CMM to its Quality Department to ensure higher standards in quality for its customers. Early in 2019, an Erowa ERC80 Machine Tending Robot was purchased to enable "lights-out" machining to meet growing demands. The company has been told repeatedly by outsiders that adding this level of technology for a small company is definitely "outside-the-box" thinking. It likes to think of it as a way to further expand its capabilities and customer base which in turns helps support the growing number of families it employs.

Since the beginning, Prosper-Tech's management has always been driven to set and meet goals. In the last several years it attained NIST 800-171 cybersecurity compliance and AS9100 certification which has allowed the company to expand its service into the defense, aerospace and space sectors.

As the company continues to grow and set new goals each year, it  will always remain committed to operating overall with the same desire for customer satisfaction as it did from the beginning in a small garage space so many years ago.
