A Message From Our President
Dear Friends,
When you think of insurance, what do you imagine? Confusing policies. Administrative headaches. Claims that never seem to work in your favor...
At ACNB Insurance Services, we’ve built something altogether different for you: a team that is relentless about removing the insurance obstacles that stand between you and success. From our same-day care to our Insurance Intelligence™ policyholder education, everything we do is designed to help you reclaim control over your coverage and your peace of mind.
Every insurance company promises to protect what matters. We promise something more: protection that works as hard as you do. We’re ready to get to work for you.

Our History
ACNB Insurance Services was founded in 1978 as Russell Insurance Group. Led by founder Frank C. Russell from our headquarters in Westminster, MD, the company steadily grew to serve hard-working community members across Maryland, Virginia, D.C., and Pennsylvania.
In 2005, Russell Insurance Group was purchased by ACNB Corporation, an independent $3.27 billion financial holding company headquartered in Gettysburg, PA. The agency was rebranded as ACNB Insurance Services in 2022 to makes our shared mission to be the independent financial services provider of choice more visible to the community members we serve.
Today, ACNB Insurance Services serves more than 10,000 customers and businesses across the Mid-Atlantic from our Westminster headquarters.
The Power of ACNB Bank in Your Corner
ACNB Insurance Services is affiliated with ACNB Corporation's other wholly owned subsidiary, ACNB Bank. Headquartered in Gettysburg, PA, ACNB Bank delivers state-of-the art banking and wealth management services, including trust and retail brokerage, via a network of banking offices and loan offices across Pennsylvania and Maryland.
A Team That Shares Your Values
At ACNB Insurance Services, we value what you value: hard work, resilience, and taking care of the people who are counting on you. That's why we go further than anyone else to keep you protected every day. Because whether it's running a family or running a business, the work you do is too important to settle for anything less.
