About the Mayor

Sean Coletti was raised in Northern Utah and Eastern Idaho. He graduated from Rigby High School and attended Ricks College prior to serving as a missionary in Seoul, Korea for two years. Afterward, he continued his education at Brigham Young University, where he received his Bachelors Degree in Political Science, and University of Connecticut Law School, all while serving in the Army National Guard as a counterintelligence agent and Korean linguist.

After school, Sean worked as a law clerk in Twin Falls and then American Samoa. Professionally, he has worked as an attorney at a local law firm since 2007, which is also when he and his family moved to Ammon. He currently serves as the Mayor of Ammon, after having served on the City Council for two terms.

Sean currently also serves on various community and state boards, including the Idaho Health Facilities Authority, the Eastern Idaho Regional Wastewater Authority, the Idaho Innovation Center, Bonneville Metropolitan Planning Organization, the Regional Development Alliance, Regional Economic Development for Idaho, and the Idaho Special Assistant United States Attorney Executive Committee. He previously served as Chairman of the Greater Idaho Falls Chamber of Commerce and also Chairman of the Upper Snake River Valley Chapter of the J. Reuben Clark Law Society.

Sean is married to Ammon native Jessi Grigg Coletti, and they have two sons, Jaydn and Sterling. They love spending time together as a family, whether indoors or outdoors—traveling, exploring, playing sports and games, or just having fun. Sean and Jessi also enjoy performing music together, as Sean is a singer and Jessi is an accomplished pianist. Their son, Jaydn, is a pianist and composer, and Sterling is a budding artist.
