About Shaun Sullivan

Assistant Vice President—National Accounts Sales and Claims Services

As Assistant Vice President of our National Accounts Sales and Claims Services team, I have the opportunity to work closely with brokers, agents, clients, and prospects. Communication is at the heart of everything we do here at Sentry, supported by our unique, accessible organizational structure. Our National Accounts field team offices are strategically located across the country, but no matter where you are, your Sentry team—myself included—is only a phone call away.

Your Sentry contact for National Accounts business insurance information.

I bring more than 20 years of industry experience to my role—and I know every conversation is an opportunity to listen and learn. At Sentry, we see you as more than just a client—you're an industry expert in your own right. This approach is at the heart of all of our business relationships. Brokers, agents, and clients can count on us to deliver. Trust isn't given—it's earned. And we're committed to upholding and nurturing that trust in everything we do.

Outside of work, you’ll find me spending quality time with my family, exercising, and traveling whenever I can.
