Dear Families,

A little while ago, we received the "all clear" from police at the high school. The students will move into advisory, where they will have the opportunity to access their cell phones to text or call parents, and we will lead them in a few calming activities to settle everyone down. Shortly after that, we will move into regular class periods.

The police now feel that it is safe to resume normal activities at the high school, but with police presence for the remainder of the day. We will not go to "lockout," but students, staff, or parents will be required to present photo ID at the gate to gain entry. The police have also advised us that normal activities at our other schools can continue.

Thank you for your cooperation and support.

Dr. Jennifer Gallagher

Good morning,

This morning, Long Beach High School received a phone threat, and as a result, immediately went into lockdown. During a lockdown, the police search the building to ensure that there is no danger inside. They are nearly finished the search, and will soon move from "lockdown" to "lockout" while the investigation into the call continues. Everyone is safe at the high school, and once the police finish the search shortly, students will be allowed to access their cell phones and contact their families.

The police have advised us that they do not feel that there is any risk to our elementary or middle schools, so we are not changing any arrival procedures there at this time. If the police advise otherwise, we will notify you immediately.

Please note that there will be a police presence at the high school throughout the day.

Dr. Jennifer Gallagher

The Long Beach High School lockdown was lifted, according to Nassau police.

Multiple NCPD cars were dispatched to the school in Lido Beach as the call came in at 7:48 a.m. on Sept. 10.

Michael DeVito, the Long Beach school district's assistant superintendent for finance and operations stated in an email to Long Beach High families and staff.

"The high school is on lockdown based on a phone call received. All students and staff are safe. Law enforcement are involved and a building search is underway. We will keep you posted."

Why the lockdown was implemented remains unclear.

In New York, a lockdown is used to protect students and staff from an immediate, violent threat inside or around the school building.

The Four Types of Attorneys (And Why Knowing Yours Changes Everything)

Picture this: It's 11 PM the night before trial. Are you buried in research? Reviewing strategic contingencies? Getting rest to stay sharp? Or perfecting your opening story? It’s certainly no secret that attorneys approach their work differently, but these differences have rarely been described systematically. Steno has developed the Attorney Work Styles framework to help attorneys understand how they naturally process information, respond to pressure and execute their work. The result is better individual performance and smoother collaboration.

Trust the Innovator Not the Imitator: Why Nassau County Homeowners Should Choose Maidenbaum

Nassau County homeowners are bracing for rising taxes and unexpected expenses that always seem to pile up. Luckily, they can authorize Maidenbaum to file their property tax grievance for the 2027/28 tax year. Acting early makes all the difference, because waiting too long could mean missing opportunities, or worse, ending up with a company that doesn’t have the experience to represent you properly. Don’t let misleading promises impact your results – if something seems too good to be true, it usually is!
