Meet Our Team

John and Sharon Wagner

After earning her CPA accreditation, Sharon started the business out of her home in 1978. Owing her first clients for their support, to include her friends and connections in the community, news of Sharon's finesse and guidance in the financial field spread quickly through word of mouth. More recommendations came from clients who were pleased and impressed with her work ethic, advice, and results. With a growing client base and after several moves around Kalamazoo County, she secured Accounting Alternative's headquarters at it's current location on Portage Road.

John is an IRS registered tax preparer. Leaving behind a mold making career, he joined his wife Sharon as a business partner in 2002. Though Sharon has always been in charge of the accounting, John took over managing payrolls and related reporting. Each have their own tax clients, but both work together in their mission: delivering professional and quality results for every client by treating them like family. Many clients have become good friends and good friends have become clients.

For more than 40 years, the Wagner's devote their skills and industry insight to families, their businesses, and communities in Southwest Michigan and beyond. To them, you're more than an ID number; you're a part of our neighborhood that deserves educated and dedicated council when making important decisions concerning capital, growth, and planning for the future. John, Sharon, and the rest of the team strive to ease the stresses of all things financial so, like them, you can focus more on what's important in your world and close to your heart.
