And Celebrating a New Chapter with Chief Holly Arndt

In every town, there are individuals whose dedication quietly shapes the character and safety of a community. In Columbia, Pennsylvania, Chief Jack Brommer stands among those few.

As of May 1, 2026, Chief Brommer officially retired as Chief of Police, concluding a distinguished career that began in 1997 and led to his appointment as chief in 2011.
His retirement marks not an end, but a transition—as he now continues to serve Columbia in a new role as Borough Manager.

A Career Defined by Dedication

From patrol officer to chief, Jack Brommer’s career reflects nearly three decades of commitment to public safety.

Under his leadership, the Columbia Borough Police Department upheld its mission to
partner with the community, preserve peace, and enforce the law with exemplary service—a mission grounded in trust between officers and residents.

Chief Brommer’s leadership brought stability, professionalism, and community connection to the department—qualities that have strengthened Columbia for years and will continue to define it moving forward.

A Legacy of Leadership and Mentorship

One of the greatest measures of a leader is what they leave behind—and Chief Brommer leaves behind a department prepared for the future.

Through mentorship and guidance, he helped pave the way for Holly Arndt, who now steps into history as Columbia Borough’s first female Chief of Police.

Her promotion is not just a milestone—it is a continuation of the values Chief Brommer helped instill:
service, accountability, and commitment to community.

A Historic Moment for Columbia

This transition represents both reflection and progress.

Chief Brommer’s retirement closes a remarkable chapter of steady leadership, while Chief Arndt’s appointment opens a new era—one shaped by experience, dedication, and forward-looking vision.

Together, these moments define a significant point in Columbia’s history—one built on continuity, trust, and evolution.
