Bollinger, the Short Hills, N.J.-based insurance agency, has acquired the Patterson-McKenna Agency of Wall, N.J.

The purchase marks the 37th for Bollinger in recent years, company officials said in a statement.

The agency, also known as PMA Insurance, was founded in 1978 by G. Wayne Patterson and Robert F. McKenna, who will now serve as senior vice presidents for Bollinger.

McKenna will continue to run the 20-employee Wall office.

“We strongly believe that the resources and enhanced capabilities realized from this new relationship will greatly benefit both our current and future Monmouth and Ocean county clients,” McKenna said in a statement.
