Mark Van Paasschen

About the Attorney

Mark is an experienced civil litigation attorney who has a reputation among his peers for being a fierce advocate for injured Oklahomans. His approach to cases has been described as creative and innovative.

Mark began his legal career in 2013 by opening his own solo personal injury law practice. Since then he has vigorously fought the big insurance companies on behalf of his clients. Mark begins every representation by treating each client with compassion and respect for everything they have been through that led them to Bison Law Firm for help. Mark’s approach from that point is to work with every client as a strategic partner in navigating the sometimes complicated world of medical care and treatment and insurance negotiations. Mark’s experience combined with his genuine compassion and perseverance allow him to break down complex legal matters in a relatable way for his clients.

Mark is a Canadian County resident who lives just a few minutes from Bison Law Firm. He is the stadium Public Address announcer for Mustang High School football and basketball games. He is also a freelance employee for the Oklahoma City Thunder, and the Oklahoma City Baseball Club. Mark is also an active member of Crossings Community Church. In his spare time (which there isn’t much of), you can find Mark on the golf course or cruising the lake!

Mark is licensed to practice in state and federal court in Oklahoma. He is also licensed to practice law in his home state of Texas.
