Mark grew up on Whidbey Island, moving to Colorado Springs in his early teen years. Mark's inspiration to practice law came at a small community college on Colorado's Western Slope, when a professor described the far-reaching impact a small nuance could have on the outcome of a legal case. From there, he attended the University of Colorado of Colorado Boulder, where he earned a Bachelor of Arts in political science. After several years as a law enforcement officer in western Kansas, Mark returned to the University of Colorado for law school. He was elected chairman of the law school's honor council, leading amendments to the honor code to ensure fair and just process. In law school, Mark represented parents accused of child neglect, and looked out for the interests of children as a guardian ad litem. He also practiced as a law student with a district attorney’s office, prosecuting cases ranging from parking tickets to domestic violence. Mark knows how important the details of each case are, and is dedicated to making every nuance work in favor of his clients.
In his free time, Mark volunteers both as a reserve police officer and in the Civil Air Patrol, and enjoys exploring the beauty of northern Colorado with his wife and two children.
