Meet Preston
A Proven Prosecutor. A Courageous Leader. A Father Fighting for Spokane’s Future.
For over a decade, Preston McCollam has stood on the front lines of justice in Spokane County. As a seasoned Deputy Prosecuting Attorney since 2013, and now serving as Chief Criminal Deputy, Preston has made it his mission to protect families, uphold the law, and ensure that the crime victims have meaningful access to justice.
Preston’s career has not been built on headlines, but on hard work: securing convictions against violent offenders, working hand-in-hand with regional law enforcement partners, and pushing back against the rising tide of crime with conviction and compassion. Preston’s tireless work in expanding meaningful relationships with local and federal law enforcement agencies has earned him the respect and endorsement of the everyday heroes in our community.
Preston knows that effective leadership is about more than courtroom appearances or personal achievements. It takes grit and strength of character in the middle of the storm. When others fled in the face of a challenge, Preston proved time and again that he will not run from adversity, instead, he tirelessly fights for what is right. His career has always been driven by the desire to leave things better than he found them. To help those in need, regardless of growing barriers to accountability.
A person’s true character is never more on display than when entrusted with both power and responsibility, Preston has demonstrated time and again that he handles both with humility and a sensitivity to the fact he is accountable to the public. He knows that real justice is not measured by political soundbites or empty promises, but by impact: safer neighborhoods, fewer victims, and a system the community can trust.
Preston's approach is practical and principled. He is willing to listen to others and will continue to be responsive to Spokane's unique challenges while staying grounded in real-world experience. Preston believes in pursuing justice without fear or favor. Choosing what is right over rhetoric or ideology, and he will continue taking that approach in his role as the Prosecutor for Spokane County.
