Competent on the case, but communication was inconsistent

I hired Mr. Costigan after my family was affected by contaminated well water in our neighborhood. His background in environmental law from Roger Williams University and his recognition in that field were clear strengths. He understood the technical aspects of the case and his three-plus years focusing on these Rhode Island-specific issues showed. We achieved a settlement, which was the primary goal. However, the experience was mixed. There were periods where updates were infrequent, and responses to emails sometimes took several days, which added to our stress during an already difficult time. While his legal competence in product liability and environmental cases is evident, the client management side felt just adequate. He got the job done, but the process could have been smoother with more consistent communication.
