PDI is an Indianapolis-based wholesale brokerage firm working with thousands of retail insurance agents, brokers, architects, engineers and contractors in nearly all 50 states. PDI started in 1980. And in all that time, we really haven’t changed much. We still handle a single line of coverage: Errors & omissions for design professionals. What we have done though, is grown: In experience, knowledge, and in the range of coverage options we can offer.
