Mattson Smith


Mattson Smith is a passionate advocate who believes in working not just for the client, but with them, to find the best outcomes at each stage of the criminal process.

Mattson was raised in a small town in South Carolina, where he learned early that our justice system cannot function without dedicated attorneys who will not only represent their clients, but passionately advocate on their behalf. This passion followed Mattson to college at Furman University where he interned with an International Human Rights Group in Brussels, Belgium, as well as at a legal non-profit in Columbia, South Carolina, dedicated to indigent rights.

Following college, Mattson moved to Colorado to pursue his Juris Doctorate at the University of Denver, where he focused his energy into criminal defense. He spent a year working in the criminal defense clinic at DU and interned with the Colorado Public Defender's Office. His time working on issues ranging from DUI to Sex Assault on a Child, reaffirmed Mattson’s earliest belief that simply representing a defendant is not enough. Criminal Defense requires a holistic approach: understanding your client’s circumstances, their goals, and their experiences, not just through the lens of a criminal trial, but as it relates to their past, present, and future.  Mattson is an enthusiastic about joining the Law Firm’s team and is ready to help guide you through each stage of the criminal process.
