Irvine, California — The Irvine City Council has appointed Sean Crumby as the interim City Manager, effective July 7. This decision was made during a special council meeting, where Crumby, the current Assistant City Manager, will succeed Oliver C. Chi, who is set to depart for a new role as City Manager of Santa Monica. Chi’s last day in office will be July 6.

His role has also included responsibility for various environmental initiatives linked to the Active Transportation Program, aimed at promoting sustainable practices within the community.
In December 2024, he was promoted to Assistant City Manager, where he focused on Great Park and External Operations. Crumby’s nearly three decades of experience in municipal government have equipped him with strong executive leadership skills, making him well-prepared for the challenges of the interim position.

The City Council plans to review Crumby’s contract during their meeting on June 24, formally paving the way for his interim management role. Crumby, who has been married to his wife, Clarice, for 21 years, brings a personal touch to his leadership style. The couple shares their home with two pet puppies, reflecting a balanced approach to work and personal life.
Overall, Crumby’s appointment comes at a crucial time for the City of Irvine as it navigates a leadership change and prepares to continue pursuing its goals for sustainable growth and community development.
