Mersen hired Serenus Johnson Construction to build a large addition to our Bay City manufacturing facility in 2014. This was a multi-million dollar project and took a little over a year to complete. Our team experienced excellent customer service from Bill and Keith Woolwine during the entire project. We are confident that we received superior value for the money spent. Although there were several mid-project design changes and unexpected issues, we continually experienced flexibility in dealing with our needs. There appeared to be good coordination between Serenus Johnson personnel and the sub-contractors that they selected. Our experience working with Serenus Johnson was positive from start to finish. Whether an issue arose at a meeting, on the phone, or in an email, it was promptly and professionally answered. Mersen is extremely pleased with the quality of our addition and highly recommend Serenus Johnson Construction to others looking for premium construction accomplished by a team with integrity.
