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.

-PSALM 128-

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 a year, Prosper-Tech had hired its first skilled employee and outgrew the garage, sending its owners in search of a larger work space to handle their rapidly expanding business.

2008 - 2013

During this almost 6-year span, Prosper-Tech truly found its stride within the manufacturing world. Operating out of a 3,600 square foot facility in Lenox, MI, Prosper-Tech welcomed two additional staff members as well as a new Haas CNC VM-2 Vertical Machining Center. Their growing production abilities and work force was accompanied by an increased workload and expanding number of satisfied customers. In May of 2013, it was once again time to move to a larger facility where Proser-Tech could successfully meet its growing demand.

2013 - Present

In 2013, Prosper-Tech was excited to move to its own 10,000 square foot state-of-the-art facility in the Devroy’s hometown of Richmond, MI. Since the move, the company has acquired two new Haas CNC Machining Centers, a VM-3 & a UMC-750, plus an additional Charmilles Roboform 40. This new technology has allowed the company to further expand its capabilities and customer base. In 2015, Prosper-Tech became ISO 9001 certified, to ensure its products and services will continue to uphold set quality standards for years to come. Within this large, immaculate manufacturing facility, Prosper-Tech operates with the same commitment to customer satisfaction it did while operating out of a small garage space so many years ago.
