How We Came to Be

The agency had its beginnings when Frank White started writing business with Grange Mutual Casualty in 1935, the very same year that Grange Mutual was formed as a company. This agency was operated from his residence where, some years later, he was joined by his nephew, Darrell Williamson.

After working with Frank for a time, Darrell purchased his own agency with his wife Shirley and moved to a new location in 1962. The following year in 1963 the business became incorporated with the addition of the new co-owners Dean and Ruth Baughman. The name was changed to Williamson-Baughman Insurance and several agencies were brought in to form the new one. The first Grange Mutual agencies purchased were from Lulu Vandenbark (one of the original founders of Grange Mutual) and Stanley Welsh. The agency then purchased Mary Harlan, Sumner Cohagon, and Darrell’s Uncle Frank White’s agencies at the company’s request.

The name once again changed back to Williamson Insurance Service in the 1990’s after the retirement of Dean Baughman in 1992. That same year, Darrell and Shirley’s son, Jeff and his wife Connie, joined the agency as co-owners. Darrell and Shirley retired in March of 1997 and in 2008 the company saw its fourth generation family member, when Jason (Jeff and Connie’s son) joined the staff. A year later in 2009, the first expansion office was opened in Newark.

We work with a wide variety of individuals and businesses throughout Central Ohio and our company has grown to proudly serve the Ohio communities of Zanesville, Newark, Pataskala, Buckeye Lake, Cambridge, Dresden, Granville, Heath, Nashport and New Concord.

We’re an independent insurance agency offering a comprehensive suite of insurance solutions to protect your business and your life from the unexpected. We don’t just sell insurance. We work closely with clients to help them make important and informed decisions every day when it comes to protection and their future.

Because we’re independent, our priority is you – not the insurance company. We represent many different insurance companies which offer a wide variety of coverage options and price points. Our goal is to deliver the right blend of price, coverage and service.

Our insurance advisors are there to help you through all the changes in your life and your business, whether you’re going from renting an apartment to buying a home, adding a partner to your business, getting married, renovating your home, adding a teen driver to your auto policy or revamping your employee benefits plan.
