I am providing this testimonial to express my deep-felt respect for, and recommendation of, a longtime professional colleague.

I have known Tom Stilwell both personally and professionally for decades, and have always been pleased to recommend his firm to clients seeking a referral for a construction contractor.

Tom has successfully constructed numerous projects which Broeske Architects & Associates has documented. On various occasions I have relied on Tom’s guidance, suggestions, and judgement in regard to project plan preparation, to formulate the most appropriate construction detailing.

I would highly recommend Tom Stilwell’s firm for future construction consideration.

I want to thank you for the excellent work you did for us remodeling our dealership. Your construction team was a pleasure to work with, very professional and thorough from start to finish. We were also very impressed with the working relationships you maintained with the City, as well as Engineers, Architects and everyone else involved with the project. Our dealership has never looked better. Thank you for all your hard work and dedication!
