Our services aren't unique; many firms do what we do. The difference, then, is us. We don't chase projects—we build relationships and we try to instill that feeling in every member of our staff.

Our Customers

Love Our Service


    Mark Voss | Judson Memorial Baptist Church

    Church projects happen at infrequent intervals and are important to the congregation as well as the building committee. CTR was great in the explanation of various selections that met our needs and our budget. There was no one-size-fits-all design. They played an active role in the early conceptual design process.


    Todd Gute | AIA MayotteGroup Architects

    Senior staff at CTR regularly assert themselves during our programming and conceptual design process, insuring MEP space requirements are addressed early. We appreciate their willingness to participate and contribute.


    Diane Schimizzi | PE,Michigan State University

    With over 500 buildings on campus, our in-house staff relies on our consultants to be self-directing on project assignments. CTR is able to independently move projects forward from design through construction without requiring detailed directions, while keeping our staff informed. CTR always interacts in a professional manner with faculty and administrative staff, as well as with Physical Plant staff.


    Dave Burt | Genesee Intermediate School District

    With the special student population in our buildings, the environment is a critical part of the learning process. CTR has come through with HVAC designs in all our buildings that address the needs of both the students and the operations staff. We've been very happy with the projects they've completed and we've developed trust in their input.


    Steve Lathrop | Okemos Public Schools Operations Director

    It's apparent from the work CTR has done for our district that they understand not only the design process, but the implementation of MEP projects. From RFP support to construction administration, CTR has provided leadership on our building projects. They're a resource I repeatedly use and trust.


    Tom Reder | AIA, Bergmann Associates

    CTR has a great understanding of the retail world. From shell development to whiteboxes to tenant improvement projects, their retail team has provided quick and efficient MEP designs in this fast-paced environment. Whether it's an unplanned field visit or a call to a utility company, CTR steps up and contributes to the overall effort.
