Attorney Trosvig has represented our company on numerous occasions over the past 10 years. His attention to detail and knowledge of laws are unsurpassed. He is very well spoken in the courtroom and will also simplify things for the average Joe to understand and he gets results! I would highly recommend him.

I attended law school with Katelyn Spangrud. Katelyn exhibits one of the highest levels of passion for client advocacy I have seen in my attorney peers and her love for the practice of law is near unparalleled. Katelyn is also an outstanding collaborator with excellent work ethic.
