Why Smart Clients Choose
Mercer Flanagan

While other firms treat you like a number, we build relationships that save you money and stress.

Most CPAs rush through returns without knowing your situation. We combine personal attention with expert knowledge to deliver results others can't match.

Personal Relationships Matter

Others shuffle you between staff who don't know your history. We know your name, family, and financial situation personally, leading to better tax outcomes every year.

Accurate CPA Review

While others rely on junior or even overseas staff, only experienced CPAs review every tax return, catching errors and finding deductions others miss for maximum accuracy.

Non-Profit, Estate & Trust Specialists

Most firms avoid complex estate and trust work. We specialize in what others won't touch, handling Non-profit organizations, probate, inheritance, and complex tax situations with expertise.

Year-Round Support Access

Other firms disappear after tax season. We're available year-round for questions—from complex planning to simple tax questions, giving you peace of mind always.

Stability You Can Count On

Established in 1971, we are proud of our experienced, stable team ready to build long-term relationships you can rely on for decades.

Service Your Way

Others force digital portals on everyone. We offer the choice between modern digital tools and traditional in-person service, working however you're comfortable.

When Your CPA Doesn't Know You, You Lose More Than Money

Beyond missed deductions, impersonal tax service creates chronic worry, leaves you vulnerable to costly mistakes, and eliminates the peace of mind that comes from trusted professional relationships. We will meet your for in-person interview or a zoom call, if you prefer. Rather just upload your documents on our portal, we can help you whatever your preference is.
