The Bean Counters

  • Megan Genest Tarnow
    Megan Genest Tarnow Principal

    Megan founded the Mobius Group in 2000 with a vision of providing rock-solid financials to small nonprofit organizations. She comes from a long line of small business people, and began working in her family’s hearing aid dealership at the age of 10. With a BA in Theatre from Gustavus Adolphus College with a focus on Directing, she’s a pro at keeping an eye on both the details and the big picture, and she knows how to translate Accounting into Plain English. Her global viewpoint  was honed during four years in Japan with her husband, Tom, where she taught English, studied Japanese, performed butoh, and gave birth to her oldest son.

    She first became a Certified QuickBooks ProAdvisor in 2002, is a Certified Nonprofit Accounting Professional (CNAP), has a Mini-MBA in NonProfit Finance from the University of Saint Thomas, and spent over a year manning the phones doing tech support for QuickBooks Made Easy. She is a long-time member of the NonProfit Financial Group of Minnesota, started the QuickBooks for Nonprofits group on Facebook, and is currently the Vice Chair of the Board of the Charities Review Council. Basically, she takes this nonprofit finance stuff REALLY seriously. Megan has developed a mantra that guides her work: Take your time. Think it through. Do it once. Do it right.

Shea has quickly become knowledgeable of basic accounting principles and programs, and has helped Mobius to build its accounting software integrations.

History + Vision

Since 2000, The Mobius Group has provided accounting consulting to mission-driven nonprofit organizations using a simple concept to propel its work: create elegant solutions. An “elegant solution” is a mathematical and engineering term meaning to achieve the maximum desired result in the simplest possible way.  Think about that: the maximum desired result in the simplest possible way.

We know that some of you may see the whole accounting function as a necessary evil, with the emphasis on “evil”.  We’d put it back on “necessary.”  You bet, we “count the beans”. But we know in the end, the beans are not the point; they are a pivotal part of the end result — your mission, your purpose, your story.

We take our name from the Mobius strip, with its single surface — no inside, no outside, one continuous edge.  We partner with each client, building strong relationships.  No inside, no outside.  We build strong, accountable financial systems that provide crucial information to internal and external stakeholders.

We help you know where you stand, with solid data and a firm foundation to propel your actions. We believe this, like everything you do, is “mission-critical.” We keep you focused on your mission.

“Mobius Group helped our organization streamline our financial systems to help us focus on our mission with vigor and clarity. The staff is easy to work with and understand the challenges of nonprofits. I would recommend their services to anyone wanting best practices in financial stewardship of their donor given resources.”
