For the last twenty years, Mary Beth’s primary practice has focused on public works and infrastructure construction law, including construction contracting and construction claims resolution.

Mary Beth understands what it takes to get a project built and what delays and claims can do to that process.

She also has experience in false claim actions against contractors for inflating or falsely submitting extra work claims.
