"Don managed the construction of our new 110,000 SF cold storage facility in Des Moines Iowa. Don spent considerable time explaining the process of the construction and invited my team to join all meetings with the sub-contractors. From the onset, Don’s decades of experience was apparent as he interacted with the subs, challenging and confirming their work standards.  Don was very tough on the subs, but at the same time was able to ingratiate himself, so they all worked together and solved problems without significant conflict, which I learned often compromises the build process. 


I hired a third-party consultant to do a monthly evaluation of the build, and they remarked that they had never seen a cleaner, better run, site in their career.


Don is a true professional!"

 "I have worked with Don for well over a decade in construction. He has always been a man of his word and a stand-up guy.

He knows how to schedule trades, so they're not "on top" of each other. He has the working knowledge of how the finishes piece together because he has studied the prints and knows who's next to finish. He is one individual I would want on my team! I've completed several jobs with him over the years."

"Buzz" your friendly neighborhood door guy!
