After an employee was severely injured by an escaped liquid, we hired NME to determine the cause and origin of the leakage and what break down in procedures may have occurred to allow this accident. We were very impressed by Dr. Niebuhr’s level of professionalism, attention to detail and clear explanation of the issues at hand. I would hire his firm again in the future.”
