Case Studies & Testimonials

Here are a few words from key clients about why they chose Olsen Thielen.

“I have worked other places where I had to tell the auditors about the industry and bring them up to speed on accounting. Olsen Thielen brings me up to speed, and their expertise helps us in more ways than just accounting. They relieve us from producing reports and information already available from them. I value their familiarity with our company; their recommendations are always in proper context.”

Ronald Laqua, Manager, Halstad Telephone Company, Halstad, MN, client since 1980s

“I appreciate their promptness, efficiency and accuracy of work. We can call anytime and get answers in a couple of hours. They know our organization inside and out and are able to give me exact information on payroll to fiscal year end to auditing to pension issues – you name it. They have all our bases covered. OT is a phenomenal group of people. They have specialists in all areas and work as a real team to help us.”

“Based on our history and the other companies I have sent to them, they have a real concern for your organization and make it a personal relationship. It is almost like having hired an in-house accountant.”

“I think it was a great find to discover them 20 years ago. Our commitment to excellence and quality in the medical field matches theirs in the area of accounting. We share the same ideas and values about quality.”

Douglas Fischer, Capitol Orthopedics, Ltd., client since 1984

“Sometimes there is new staff, but it has been easy to work with a new person; it doesn’t feel like we are getting new kids on the block. Olsen Thielen provides continuity, and the project manager is just an email away.”

William J. Nelson, President, The Cooperative Foundation, client since 1990s
