What Are the Key Differences Between Marsh McLennan Agency and Travelers Professional Liability (E&O) Insurance?

Which Professional Work Is Named

Travelers lists separate products for accountants, design professionals, lawyers, real-estate and insurance professionals, managed care, financial institutions, and other client-facing work. MMA names architects-and-engineers and lawyers lines in its overview but does not enumerate a comparable profession list; buyers should ask which team and form handle their specific specialty. [3] [5]

Placement Scope and Buying Route

Travelers directs buyers to an independent agent. MMA asks organizations to contact its own adviser or specialist, so the placement relationship differs; in both cases, the quote must identify the insurer and policy terms. [3] [5]
