B.W. Kennedy & Company is an open shop Builder and Construction Manager incorporated in 2009 by Owner Brian Kennedy. With more than 20 years of hands on building and management experience, Brian founded the firm as a full service Construction Manager to better serve the needs of clients.

He quickly moved through the construction ranks to become a project executive and manage construction of large projects, including a new 55,000 sq. ft. music center and a LEED Gold residence hall. Brian has since founded B.W. Kennedy & Company, a firm of builders who share his building passion.

Because we are builders and understand the detail behind an architect’s design, we can more easily quantify program and commit to cost during the conceptual stage of a project. Most importantly, we deliver on our client commitments with on-time and on-budget projects.  

Our ability to uphold client commitments has allowed us to build strong momentum and strengthen our reputation for superior client service and quality workmanship. Clients appreciate our How We Do Business Mantra: Our commitment to their goals, our integrity in dealing openly and honestly with them, and our unwavering dedication to deliver a project that exceeds their expectations.
