Leveraging three decades worth of experience in working with the construction industry with a thorough knowledge of the unique challenges facing the industry today, Don Leach has helped a wide variety of clients accomplish their objectives. Having assisted clients through both litigation and transactional matters, Don is able to tailor his approach to help clients reach their intended resolution in a cost-effective manner.

Working in both the public and private sector, and representing owners, developers and contractors, Don utilizes his knowledge about the business, financial and legal challenges facing the construction industry to provide his clients with the advantages they need. A former president of the Builders Exchange of Central Ohio, where he received the Cornerstone Award, as well as a member of the Ohio Board of Building Standards, Don's familiarity and relationships within the industry allow his clients to benefit from insight gained only through extensive experience and relationships. From drafting and negotiating contracts to defending and prosecuting construction lien, contract and bond disputes, Don’s practical approach ensures clients’ needs and goals are met in a timely, efficient manner.

Additionally, Don, who spent five years working for the President of the Ohio Senate, has served in a number of administrative and legislative roles, providing him with valuable insight into the construction industry. For instance, Don assisted in the drafting of Ohio’s mechanics’ lien law, and has served as the General Counsel to the Central Ohio Chapter of Associated Builders and Contractors. In addition, as a member of the Ohio Board of Building Standards, his work involves establishing Ohio building codes and regulating building officials. His array of experiences in dealing with government and public policy matters enable him to offer additional unique perspectives and solutions to clients. In that regard, he frequently collaborates with Dinsmore Public Sector Advisors on behalf of clients. He served two terms on Upper Arlington City Council and was mayor and president of council for five of those eight years.
