Our History

J.M. Insurance Agency was founded in March of 2012 with no clientele base.  Our President, Beau F. Massengille, had a vision early on in his career to own his own agency.  So, when the opportunity came to represent Erie Insurance Group, he was very excited.  He knew with a solid carrier like the Erie.  He would be able to make his vision a reality.  The agency was created on the mission of Building Trusted Relationships which has placed J.M. Insurance Agency as one of the leading insurance agencies in our area.

Lebanon Insurance Agency

Welcome to our agency family! J.M. Insurance Agency acquired Lebanon Insurance Agency in October 2017. The agency was founded by Earl Easterly in 1968 and was ran by his sons, Mark & Gary Easterly up to the acquisition. Our agencies shared many of the same values that we try to deliver to our clients which starts and ends on the foundation of Building Trusted Relationships. Since we had a common carrier representation, we are able to continue delivering a consistent service to our new clients which is an asset to you. We look forward to serving our new clientele base, and we are grateful to the Easterly Family for entrusting us with their clients whom have been a part of their family since 1968. Your protection and security is our number one concern!

Sirls-London Agency

We are pleased to announce that Sirls-London Agency has joined our agency family as of June 1, 2018. In 1971 Bill Sirls founded the agency which was then named Gallatin Insurance Services. In 1978, David B. London joined his father-in-law in the agency, and they changed the name to Sirls-London Agency. Since 1971, they have had a commitment to serve and build relationships to help folks with their protection and security. It makes for a great match for us to join forces. Nothing changes, with our new agency family, we will have additional locations and access to new markets that will only help us to serve you better. You are important to us, and we are confident that our new relationship will serve us all well.

Our Name

So, where does J.M. come from?  When thinking about a name for the agency, it was the first thing that came to mind for our founder, Beau.  Beau’s father was James E. Massengille whom passed away in May of 1996.  James was a person who had the entrepreneur spirit and a passion to help others.  He would certainly be thrilled about this opportunity to help others and is looking over us each day.  J.M. Insurance Agency is named after James E. Massengille as way to remember his legacy.
