Olsen Thielen Celebrates 100 Years

Over 100 years ago, Olsen Thielen was founded on the belief that personal attention, trust, and quality service were the key elements to helping our clients succeed, and that commitment remains.  

Our firm began by providing accounting and compliance services for the Rural Telecom industry, but now, we have grown into so much more.


At Olsen Thielen, accounting is more than numbers, which is why we don’t just recite information. We teach businesses how to understand what those numbers mean and apply that to every decision they make.

Business climates are constantly evolving, but so are we.  We continue to expand our non-traditional accounting services to honor our commitment in guiding our clients towards a bright future. Our longevity and growth are attributed to building strong relationships. When you join with Olsen Thielen, you become more than a client. You become part of our family. And like family, we’ll be there to help you whenever you need us.

Contact us today to see how we can help your business grow.
