About Our Firm

About Our Firm

Big firm perspective, small firm service

Mangum & Associates was founded in 1971 by Bill and Paige Mangum. The business started in their living room but quickly grew and evolved into a thriving accounting practice in downtown Brunswick. Throughout that growth, the practice never lost sight of the core values that created their success- attention to detail and excellent client service.


In 2015, Mangum & Associates was acquired by Casey Mangum, after 7 years of working at Ernst & Young, LLP. He aspired to bring the knowledge he gained working with some of the nation’s most successful companies to the communities and local businesses of Maine.


We believe the combination of big firm perspective with small firm service provides our clients with an experience unmatched by our competitors. Whether you are an individual who wants help with tax preparation or a business looking to grow, let us show you the difference today.
