Our Step-By-Step Proprietary Process

The feedback we receive most often is how clear and straightforward our design and building process is.  Here’s how it was developed:

Back in 1963, when John TerWisscha struck out on his own as a Contractor, he had one truck and a dream.  His “process” involved talking around a kitchen table over coffee and cookies, with homeowners who wanted a quality home built for a growing family.

This heritage of truly listening and collaborating with the Client has been passed on and held tightly through the years.

 

 

As TWC grew into specific industries, like Veterinarian Clinics and Dental Offices, it became apparent that a specific step-by-step, guided process was required.  This allows the current team to protect a space for communication, just like John did.

The next generation of TerWisscha Construction owners claimed this process as a roadmap: necessary for cost-saving efficiencies AND a stellar end result.

Trust us when we say, “Each step is strategic, instructive, and designed for the benefit of the Client (and their Clients).”
