New Mayor Takes Office In Mendham Following Glassner's Departure

MENDHAM, NJ — It's official: Mendham Borough has a new temporary leader.

The Borough Council president has taken on mayoral duties after Mayor Christine Serrano Glassner resigned for a White House position, the council said in a Monday evening message to the community.

In a memo, the all-Republican, six-member council announced that Council President Neil Sullivan "will immediately assume the administrative duties of the mayor" in accordance with state and borough administrative codes.

This will be temporary, as the Borough Council will begin the legal process to fill the mayor’s vacancy, ensuring democratic principles are upheld and the borough’s governance remains stable and effective.

The council also invited residents to attend this week's meeting at 7 p.m. Wednesday at the Garabrant Center, 4 Wilson St., as well as future meetings, to ask questions about the upcoming selection process.

"Transparency and open communication are the cornerstones of our governance. We are committed to keeping you informed throughout this transition period and beyond," the council shared.

In the meantime, all personnel will remain in place, working to maintain the services and operations residents rely on. The council emphasized its goal to ensure Mendham Borough continues to operate efficiently and without disruption.

The council also assured community members that it remains focused on several key priorities, including:

• Affordable Housing Planning: The council is committed to meeting state-mandated deadlines for the 4th Round of affordable housing planning, ensuring the borough fulfills its obligations while preserving the community's character.
• Parks and Recreation Enhancements: Efforts are underway to expand and improve Parks and Recreation programs, providing opportunities for residents of all ages to enjoy the borough’s natural beauty and community events.
• Public Safety: The council is collaborating with Public Safety Director Craig and Officer-in-Charge McNichol on long-term strategic planning for the police department, ensuring the continued safety and well-being of residents.

"Thank you for your continued support and engagement. Together, we will navigate this transition and continue to build a strong and vibrant future for Mendham Borough," the council wrote.

Mayor Serrano Glassner, who served for more than six years, announced her resignation in a letter posted on the borough’s website this past weekend. With her current term running through the end of 2026, a special election will be required to select her successor.

Serrano Glassner, whose husband, Michael Glassner, was Donald Trump’s deputy campaign manager, did not specify the role she will be taking and could not be reached for comment. However, a report by the New Jersey Globe, said she is reportedly set to join the White House's Office of Intergovernmental Affairs.
