Company History

We are an independent MGA & wholesale brokerage with family values. Founded in 1986 by Frank Mastowski and his wife Ellen, we have grown to represent a portfolio of over 150 admitted and non-admitted markets between our in-house binding authority and brokerage capabilities.

Our strength is not only in our relationships with our clients and markets, but our ability to understand the risk and help you with creative placement solutions. Through innovative technology, we continue to find ways to stay cutting-edge and provide additional opportunities with OASIS 24/7 quoting, accounting and comparative rating.

We continue to look forward, while never forgetting where we came from. Great people are what brought us here- from our diverse and multilingual employees, to our carrier partnerships and most importantly our clients.
