Skilled and dedicated counsel for our business dispute

Grant Killoran provided excellent representation for our company during a complex contract dispute. His deep knowledge of commercial litigation, honed over a decade, was evident throughout the process. We particularly valued his straightforward assessment of our case and his recognition in the field gave us confidence. While communication was sometimes slower than we'd have preferred during the initial phases, his strategic guidance and dedication to achieving a favorable settlement were outstanding. We would certainly engage him and O'Neil Cannon again for business legal matters in Milwaukee.
