Executive management
Our mission
Helping homegrown Chicagoland
businesses realize their full potential
In 2006, Signature Bank founders Mick O’Rourke, Kevin Bastuga and Bryan Duncan set out to
create the commercial banking experience they felt their customers were lacking due to
ongoing industry consolidation. That consolidation led to many privately owned, middle-market
businesses losing the personal contacts and local decision-making they had come to expect
from their previous banking partners. Signature Bank filled that void by building on decades of
personal relationships and developing a full-service, yet specialized commercial banking partner
wholly dedicated to helping privately owned businesses thrive and grow.
The Signature Bank team demonstrated their dedication to service and relationships by
investing in advanced technology, products, services and fraud prevention strategies that help
meet commercial customers’ needs more quickly and efficiently than bigger banks, while
prioritizing security for every customer transaction.
If you’re looking for high-touch, personalized service from your commercial banking team,
you’ve found it.

We founded Signature Bank for one reason
“We knew there was a better way to help mid-size businesses grow, thrive and succeed — on both a business level and a personal level. As a mid-size business owner, you don’t have time to worry about every financial detail to keep your business running smoothly. That’s what Signature Bank is all about: taking care of those details so business owners can really focus on their business.”
Board of Directors
Signature Bank’s non-employee directors support the bank’s executive management team and believe whole-
heartedly in the bank’s mission statement. Each board member provides valuable insight from a wide range
of industries, including manufacturing, investment banking, law and, most importantly, community banking.
