Home » About Our Agency

Shamrock Insurance Agency has been around since 1987, but we’ve always been up to speed with insurance to meet your needs.

Where it all began.

Founded in 1987, Shamrock Insurance Agency has offered insurance solutions to families and businesses across Ohio and beyond—all while focusing on excellence in customer service and affordability in the coverage options we provide. We expanded our agency by acquiring the assets of McAndrew Insurance Agency, which was founded after the Second World War by Robert and Edward McAndrew, which stayed in the family until its sale to Shamrock Insurance Agency. We too are a family-owned agency, and are proud to carry on the traditions of serving others first.

We are proud to be an independent insurance agency.

As an independent insurance agency, we specialize in a variety of insurance solutions to serve your needs. And because we’re independent, our priority is you—not the insurance company. We represent insurance companies in order to help you find a unique blend of price, coverage, and service. And as your insurance advisor, we’re here to educate you and to help you make informed decisions so you can be protected from the unexpected and plan for the predictable.
