Maria J. Christiaens

The spirit of entrepreneurs and the opportunities of free markets are exciting to me. I love to see a business thrive, and I like to play a part in handling the various compliance matters that shouldn't distract the owner from the bigger picture.


Maria offers clients decades of public accounting experience and expertise, including audit, tax and business consulting services. She joined Eide Bailly in 1985 and has devoted the bulk of her career to specializing in employee benefit plan audits. Today, Maria is responsible for the coordination and oversight of more than 800 employee benefit plan financial statement audits.

Maria is comfortable navigating the compliance issues that impact her clients and breaking down the information in an understandable way, so when you work with her you'll never feel lost or out of the loop. She especially likes client interaction and works best in a collaborative relationship.

When she's not busy with her audit work, Maria enjoys moving others through music with her beautiful singing voice. She is an active supporter of various choral groups, including serving as past president and singing soprano for the Magic City Singers. She's also a bit of a classic car enthusiast and loves to get outdoors to hike and camp ... Mother Nature still has the best acoustics.
