J.F. Brennan Company and Brennan Marine (Brennan) traces its roots back over 90 years ago to two brothers, James and Eugene Brennan, who left their parents’ farm in Lansing, IA, and formed a contracting company. The company grew into what is now an industry-leading inland marine construction, environmental remediation, and harbor services company. Now, four generations later, Brennan remains a family-owned entity with a strong foundation primed for future growth. Our team members are considered some of the most experienced marine professionals on the inland waterway system who bring innovation and insight to every project in which they participate. They are backed by quality equipment and extensive training programs to continually deliver exceptional value to our clients.
