more than an accounting firm

W.A. Campion Co., P.C. is more than the typical accounting firm. While we do provide traditional accounting services and tax preparation, we also offer other business advisory and financial services to our clients helping them with the financial decisions crucial to the success of their businesses.


Liman Post & Beam’s owner, Leo Kill’s relationship with W.A. Campion started 29 years ago with founder, Joe Campion. Liman Post & Beam is a custom build construction company with a lumberyard serving residential, commercial and agriculture customers across the upper Midwest. “The business keeps me and the guys busy full time estimating and building. W.A. Campion does all of our business accounting, including payroll and bill pay making sure that expenses are assigned to the right job.” Mr. Kill says. “Bill Campion is my financial advisor as well. If I do something financial I run it by him. Bill definitely keeps me out of trouble.”
Mary Kay Hawks of Mary Kay’s Bridal is proud to say, “Bill Campion is my nerdy friend and super accountant. I have worked with W.A. Campion for 16 years and he takes care of all of my financial accounting, personal and business taxes, payroll, helped me through an IRS audit and even provided help filling out all of the disclosure information when my son was applying for financial aid through Federal Student Financial Aid (FASA).” Mary Kay has expansion plans for her bridal shop in the near future and W.A.

Cliff Lake, Principal of a local music retailer has known Bill Campion for over 20 years and has employed him as his C.P.A. for the past 12 years. “As a retailer, I require a monthly review of financials to include P&L statements, and balance sheets, plus I have Campion file the monthly payroll taxes. Operating a retail business keeps me busy and there is no one on staff to handle the financials, which Campion does at a reasonable cost. Campion and his entire staff are very responsive. They get back to me same day, and often within the hour,” Lake said.
