About Us

Empowering Nonprofits and Small Businesses with Financial Clarity

Who We Serve & Why We Care

At Mangen & Associates (M&A), we bring over two decades of experience delivering reliable financial management, accounting, and bookkeeping services to both nonprofit and for-profit organizations across Ohio. We specialize in partnering with high-impact nonprofits and growth-focused small businesses, helping them scale with financial clarity, confidence, and control.

When you need strategic accounting expertise, we step in as your bookkeeper, fractional CFO, controller, or advisor, tailoring our services to fit your goals, timeline, and budget. Whether on an ongoing basis or for a specific project, we work as a seamless extension of your team.

We understand that every organization is unique—and that even the most successful leaders often wonder, “Can we do better?”  You may be a solo bookkeeper stretched thin, or a founder juggling HR, operations, and finances. It may feel chaotic, but you’re not alone. Our role is to simplify the financial side of your organization so you can lead with focus and peace of mind.
