Company History

Jimcor Agencies is a family run business with family values. Started in 1986 by Frank Mastowski and his wife Ellen, the company has now grown to hold a portfolio of over 150 Admitted and Non-Admitted Markets between its In-house Binding Authority and Brokerage capabilities.

Jimcor’s strength is not only in our relationships with clients and markets, but in our ability to understand the risk and help you in the correct placement of the risk.

Through technology Jimcor will continue to find new ways to grow and work with the insurance community, always keeping the relationships that brought us here intact. Providing 24 / 7 quoting and online services is just one example of the dedication to giving producers the services they need to get the business written.

We will continue to look forward and never forget where we came from. Great people are what brought us here - from our multilingual and diverse employees, to our Admitted and Non-admitted markets and most importantly, our clients.
