A Local Insurance Agency with Deep Roots in South Carolina

People across Greenville and the Upstate turn to The Sullivan Agency when they want more than just a policy. Our clients want real advice, personal attention, and insurance agents who have their back when it matters most. That’s exactly why we’re here.


Our story starts with Gary Sullivan—a claims specialist turned agency owner—who saw firsthand how many people struggled with the fine print of their policies and didn’t know where to turn when things went wrong. He started The Sullivan Agency to change that. From the beginning, our mission has been simple: help South Carolina families and businesses feel informed, confident, and supported when it comes to their insurance.

We Put Education & Advocacy First

Insurance should never feel like a mystery or a transaction. Whether we’re explaining liability coverage to a first-time homeowner in Anderson or helping a small business owner in Spartanburg understand risk, we take the time to make things clear.


That starts with listening. We ask the right questions, walk you through your options, and make sure you’re choosing coverage that fits your goals—not just the cheapest number on a screen.


And when a claim happens? We’re not going anywhere. With Gary’s decades of claims experience, our team knows how to guide you through the process, avoid common missteps, and advocate on your behalf.

Our Story:

Rooted in Central Oregon,

Built on Trust.


Frustrated with the lack of personalized service in larger, national agencies, Mollie set out to create something different—a return to the traditional values of trust, partnership, and local focus. In 2016, Summit Insurance was born with a mission to bring personal, attentive customer service back to Central Oregon businesses. Instead of a one-size-fits-all approach, Summit Insurance focuses on creating tailored solutions that meet the unique needs of each client.


By becoming an extension of your team, we provide the support, guidance, and expertise that allows you to offer valuable benefits while still achieving your business objectives. As a locally owned and operated agency, we’re proud to work alongside businesses in our community, building long-term relationships that make a real difference.

Independent, Family-Owned, and Proudly South Carolina-Based


We’re proud to be an independent insurance agency—meaning we’re not tied to any one carrier. That gives us the freedom to shop around, compare plans, and find the best value for your situation. It also means we answer to you—not a national brand or quota.


Our team is made up of real people who live and work right here in the Upstate. From Taylors to Powdersville, we’re your neighbors—and we care about what happens in our community. That’s why we believe trust, transparency, and good communication matter.

The Sullivan Agency is led by Gary Sullivan and supported by a knowledgeable, friendly staff dedicated to helping our clients every step of the way.
