Above all, your professionalism and patience in working with me in a challenging design build situation helped keep the project moving along despite having no plans/drawings to work off of whatsoever. Your communication and experience in that area was exceptional and I will certainly use Bleeker Construction again when the time comes.

I feel very fortunate that I had Bleeker Construction as my contractor. You and your team were flawless in all the facets of the build out. You collaborated so well with me, the architect, the bank, the HOA and all the subs. Mark Buchkowski, my project manager, was simply amazing. He never presented me with problems. He only had solutions. I have never met a project manager who was so organized and so skillful. He really went the extra mile. You and Mark are my first choice for any construction project moving forward.

Cory and his team are the type of people that just do whatever it takes to make a project a success. They are more than just a contractor that builds what someone tells them. They are so pro-active in listening to all of the parties involved in the project and identifying what needs to be done and then doing it, that they make a difficult business seem easy.
