Biography
Andrew John “A.J.” Manion is a Co-Founder of Manion Stigger, LLP. A.J.’s entire career has centered around construction: working as a laborer during high school; engineering education; construction project manager after college; and, for the last 30 years, attorney representing general contractors, construction managers, design-builders, and subcontractors throughout the United States.
A.J.’s goal is effective representation. A.J.’s time in construction, MBA after law school, and three decades representing leading contractors bring a deep understanding of potential solutions and strategies. Adding to his engineering and business background, A.J. is a skilled trial attorney with successful experiences in jury trials, court trials, arbitrations, and appeals, having prosecuted and defended substantial claims in a variety of construction contexts.
While always ready to litigate or arbitrate, A.J. has especially enjoyed proactively working with clients to develop processes and controls to prevent disputes in the first place. He accomplishes this through learning clients’ business models and corresponding challenges and then working with a broader team to develop and implement project management systems that proactively protect their businesses from risk.
A.J. frequently lectures on topics in the construction industry and dedicates significant time to sharing knowledge with construction industry trade groups. He is included in The Best Lawyers in America® and SuperLawyers® for Construction Law and Litigation – Construction and is the recipient of Martindale-Hubbell’s AV Preeminent® rating, given to attorneys ranked at the highest level by their peers.
