Don’t take our word for it – here’s what our clients say:

"Holland Hospital as well as our team at Lakewood/Elzinga is very pleased with your great work on the Ortho/Spine Project. This was a very challenging project on many levels and we couldn't have completed it without the help of your team. Thank you for all that you do! We're looking forward to working with you on future projects!"​

“I look forward to many more projects in the future because your team's quality and attention to details make my designs shine. During all of these projects over the years, no matter what the size, AMS personnel from the office staff to the trades have always presented themselves in an extremely professional manner and outstanding performance in everything they were involved with. I use AMS as the standard to which I gauge the performance of other MEP contractors."​

PAB Engineering

"Out of all of the subs on the job he [AMS's Project Manager] was the best at preparing change orders, the best at preparing submittals, the best at writing RFI's, the best at communicating, the best at problem-solving, and the best team member. No one else compared to his level of thoroughness on all of those items. AMS was the superstar of the job in my mind."​
