Joyce M. McChesney

Hailing from the South Hills of Pittsburgh, Joyce is the Office Manager of the North Side office of Stunkel Tax & Accounting, PC.  She loves to talk to a client whether they call her or she’s calling them.


After graduating from Mercyhurst College in Erie, Joyce taught bookkeeping for three years in the Pittsburgh Public School System. She and her CPA husband, Bill, raised two children and then Joyce decided it was time to rejoin the business community.


She completed a Master Degree from St. Francis College, as she puts it, “while having a house, a husband and two kids”. No mean feat working full-time at an iron foundry on the South Side in Human Resources and studying for her Masters at night. Joyce likes to say that after teaching and wearing steel-toed boots, she can tackle anything!


When the steel industry collapsed and with two teenagers at home, Joyce joined the firm of W. J. McChesney, CPA and became the Office Manager. This gave her the opportunity to be a working mother who was able to fit her work schedule around the kids' schedules. She had the best of both worlds – motherhood and business woman.


Joyce can be found answering correspondence, writing up tax returns for data entry, designing a spreadsheet, or acting as a liaison between our clients and our employees. Between wearing multiple hats and being both an employee and the former owner of a small business, Joyce has a unique understanding of the needs of our clients.


After 20 years of running a public accounting office, she can help steer you to the answers of whatever questions are keeping you up at night.
