I will hold myself fully accountable for my own actions.
Although I operate within a team, I will strive to make sure “MY” contribution is unmatched.
My only fear or intimidation, is not realizing my full potential.
I will attack problems big or small with confidence that I was put on this earth to solve the issue, and if not me, then who?
Complacency is my worst enemy, and it is my absolute need, to seek out innovation, obsess over efficiency, and execute daily.
As an individual, I may take backwards steps, but as a unit, SHOWTIME does not take losses.
Regardless of my past, I am now a winner, I am confident, and with a positive mindset I am not only good, I am great.

These guys are great with communication and attention to detail! I would highly recommend anyone looking to build their own custom home consider Showtime Homes!

I have worked with Matt Buman for a number of years and he is one of the most knowledgeable and experienced people in the home building industry that I have met but then I also met the rest of the team at Showtime Home and I have no doubt that they are going to be one of the best builders in Iowa. I strongly recommend them if you plan on building a home.

I have been fortunate enough to work with the Showtime team on a few different projects, and I’ve been nothing but pleased with the outcomes. They are very professional, organized and always meet their completion deadlines. Their team is responsive, and a pleasure to work with.
