"Both Medical Assurance and Professionals Group have met the unique challenges required to expand and succeed in a very competitive segment of the insurance industry, and each brings a track record of experience and commitment to this merger.

Victor T. Adamo, President and CEO of Professionals Group, said the two companies' shared history and commitment to policyholders makes the consolidation a strong fit.
