Secret to Success: “You don’t build a business-you build people-and then people build the business.” –Zig Ziglar



Dennis first joined the Scheffel Boyle team in 1977. He has over 35 years of public accounting experience and serves as Managing Principal of the firm. Dennis is a trusted, key advisor to numerous business owners and executives in our local area, and even across the U.S. His business acumen and professional knowledge stretches over multiple industries and he is a valuable tool for his coworkers and the entire Scheffel Boyle family of clients.


Dennis grew up in New Douglas, IL and still lives in town with his wife of over 40 years, Rene. He has two grown children and four grandchildren. For over 40 years, in addition to his work at Scheffel Boyle, he has also owned and operated his own family grain farm.


Dennis comes to work every day because he truly enjoys seeing his clients succeed. Some of Dennis’ clients have been with him for decades because they see the value and dedication he brings to the table. He does more than merely provide a service for his clients. He becomes an integral part of their team and works side-by-side with them to help them reach their goals. It’s important to Dennis that his work benefits not only Scheffel Boyle clients, but also his fellow coworkers. Dennis enjoys seeing the younger staff grow within the firm. He tells newly hired staff accountants to “come take my job”, and he means it. He is passionate about helping young professionals in the accounting field succeed and develop a promising career within Scheffel Boyle.
