As Founding and Managing Partner of Ciresi Conlin, Katie’s known for practicing at the intersection of science and the law. She pinpoints the advantages and disadvantages of each case, quickly and efficiently. In order to know how to maneuver your client’s case, you also need to understand your opponent’s path. Seeing through the pitfalls while recognizing the advantages both sides face helps to refine the business goals and litigation strategies for any dispute. Plus, after decades in practice, Katie’s learned that the best litigation strategy may be an unconventional one. When not working, Katie can be found at her northern Minnesota cabin, running, or encouraging her three children in some new adventure.
