Michelle Key

From caring for patients to caring for your books.

I’m Michelle, the grandma behind Grandma’s Bookkeeping, and I bring the same steady, watchful care to your numbers that I’ve always brought to my patients and my own family. After nine years in the Marine Corps and more than three decades as a registered nurse—along with earning a Master’s in Nursing Leadership and Management and an MBA along the way—discipline, clear thinking, and attention to detail are simply how I’m wired. Yavapai County has been my lifelong home, with four generations of my family now rooted in the Skull Valley area. When I work on your books, I’m looking out for a neighbor’s livelihood, not just a set of accounts. My goal is simple: to quietly handle the receipts, reports, and reconciliations in the background so you can spend more time serving customers, leading your team, and enjoying the life you’re building here, knowing a trusted local grandma is keeping an eye on the finances.
