Shana Wood
 Senior Accountant

With over 30 years of experience in the accounting world — I can honestly say I still love what I do. Accounting isn’t just numbers to me; it’s problem-solving and bringing clarity to complex financial stories. I specialize in start-to-finish month-end reporting, making sure everything balances, aligns, and tells the right story. Whether it’s digging into a discrepancy, streamlining a process, or building clean and accurate reports, I enjoy the challenge and the satisfaction that comes with getting things right. I’m known for being dependable, detail-oriented, and genuinely passionate about helping organizations understand their financial picture. After three decades, I still find joy in solving accounting challenges and supporting teams with accurate, timely information.
