Karen Benson

Karen Benson is a tax manager at SKDO, primarily working in the tax compliance and consulting side of the firm.  She enjoys working with a variety of clients, but specializes in small to mid-sized business tax preparation, consulting, and financial reporting.  She is passionate about working with businesses to succeed in an increasingly regulatory environment, whether it’s through tax saving strategies and planning, financial analysis, or business succession planning. 

Karen started at SKDO in 2007, after graduating from Olivet Nazarene University with a Bachelor of Science in Business Management and Accounting.   She passed the CPA exam in 2010 and is a member of the AICPA, Illinois CPA society, and is a Certified QuickBooks Professional Advisor.

When she’s not at SKDO, Karen enjoys spending time with her family and friends.  She loves traveling, a favorite destination being Colorado to get some fresh mountain air, hiking and good scenery.  During the summer she likes to get her fill of sunshine by biking, kayaking, and sipping a good dry white at a Michigan winery.
