Cheryl Ringler

Cheryl has been with SKDO since 2007 working as a Staff Accountant.  She works primarily in the tax department preparing corporate and individual tax returns, but also works on compilations and Personal Financial Statements.  She is a QuickBooks Pro Advisor and devotes time to helping clients with QuickBooks both at the office and out in the field. 

Cheryl attended Dordt College in Sioux Center Iowa and graduated with a degree in Business Administration/Economics.  She is currently taking the additional accounting classes she needs to sit for the CPA exam.

Outside of the office, Cheryl enjoys traveling, photography, reading and spending time with her children.  She has traveled extensively inside the United States and has visited both Mexico and Ireland outside of the country.  She hopes to visit several more European countries in the future – especially the Netherlands where her mother was born.  The rest of her time is devoted to watching her high school daughter compete in show choir competitions throughout the Midwest and visiting her boys in the city as often as possible.
