Meet Our Attorneys

The son of Mexican immigrants, attorney Aaron Tarin is a passionate Utah lawyer who is acknowledged by his colleagues as one of the leading lawyers in the complex legal world that arises when Immigration and Criminal laws collide.


A fluent Spanish speaker, Aaron received his degree from Brigham Young University in Business Management and Spanish Translation. He then received his law degree from University of Utah, S.J. Quinney College of Law.


From his early beginnings as an Immigration Court law clerk while in law school, to his later service fighting against anti-immigrant laws as the Executive Chairman of the Utah Chapter of the American Lawyers Association (AILA), Aaron has dedicated himself to furthering the rights of immigrants.


With years of experience litigating complex cases before the United States Citizenship and Immigration Service (USCIS), the Board of Immigration Appeals (BIA), as well as the Circuit Courts of Appeal, Aaron understands what it takes to win even the toughest cases.


Aaron is often called on to train other lawyers in this hybrid area known as "Crimmigration Law", which the Supreme Court of the United States has declared is one of the most "complex" and "unfamiliar", especially for lawyers who don't understand both areas of law well.


An active member of the Utah Association of Criminal Defense Lawyers (UACDL), Aaron has written several articles informing criminal defense attorneys on how to effectively represent immigrants charged with crimes. 


Aaron also serves on the Legal Panel for the American Civil Liberties Union of Utah, where he focuses on immigration and criminal related violations of civil rights.
