About Us



Professional Construction, Inc. (PCI) was founded in June of 2004 in Greenfield, WI. The thought behind establishing this company was to provide our customers with the highest level of service, workmanship and professionalism in the construction industry. Our team of carpenters brings a combined experience of over 50 years in the field.

Our employees are customer service oriented and detailed in the work they provide. We keep our job sites clean, orderly and of least disruption to the customer while working in their home or environment.

PCI was founded by Michael Grau and Keith Owsiany. Unfortunately, a year after the company’s establishment, Keith became ill with pancreatic cancer and unexpectedly passed away. This left the running of the company solely to Michael and Michelle Grau. The desire to follow Mike and Keith’s dream and continue to grow and make this company number one in the construction industry in both customer service and workmanship, keep them going.

Professional Construction, Inc. is proud to be located in Waukesha, Wisconsin, and looks forward to helping you with your next home improvement project.
