About the company

NJM Insurance Group provides property and casualty insurance mainly in the Mid-Atlantic, focusing on auto and home coverages and other P&C protection. It operates as a mutual insurer owned by its policyholders, using premium dollars to fund coverage, claims, and service rather than paying dividends to outside owners. Customers get protection through policies (notebook of auto and home insurance) and a claims process backed by financial stewardship and strong service. NJM differentiates itself by its mutual ownership model and a commitment to value-based solutions and service, plus regional recognition for auto claims experience and employer awards (e.g., leading Mid-Atlantic auto insurer in J.D. Power 2025 AIS; Forbes Best In-state Employer 2019–2025). Its stated goal is to provide value-based insurance solutions with the highest levels of service, integrity, and financial stewardship for policyholders in the Mid-Atlantic.

Simplify's Take

What believers are saying

  • June 2026 cat bond raised $250 million, enabling larger catastrophe protection.
  • October 2025 claims certification and Mid-Atlantic ranking support retention and pricing power.
  • 2026 board addition of Joseph S. Colalillo broadens governance and local network access.

What critics are saying

  • Carol Voorhees replaced Mitch Livingston in July 2025; leadership transition disrupts culture.
  • Catastrophe exposure remains concentrated in Northeast states through June 2029 reinsurance tower.
  • A severe coastal hurricane could overwhelm indemnity layers and damage surplus.

What makes NJM Insurance Group unique

  • Mutual insurer keeps policyholder focus, not public-market pressure, under Voorhees since July 2025.
  • Eight straight J.D. Power claims certifications signal operational discipline and service quality.
  • Lower Ferry Re 2026-1 shows strong capital access for Northeast storm risk.

Ocean City H.S. students to receive DUI prevention simulator training.

Ocean City H.S. students to receive DUI prevention simulator training. Driver education students at Ocean City High School will learn how it feels to drive impaired when they take the wheel of a desktop simulator during training sessions at the school from April 21 through April 28. The simulator sessions are offered through a partnership between the John R. Elliott HERO Campaign, Cape May County Prosecutor's Office, Ocean City Police Department and NJM Insurance. A dedication ceremony for the new simulator will be held Tuesday, April 21, at noon in the high school's Community Room. The computer program challenges students to "drive" through a virtual town, displayed on a video screen, while their responses are altered to resemble intoxication. The effects typically cause students to run through stop signs and traffic lights and even cause virtual accidents. "At first, students enjoy the fun and challenge of the simulator, until they experience problems and realize that drinking and driving is no joke and can have serious consequences," said Bill Elliott, founder and chairman of the HERO Campaign. The John R. Elliott HERO Campaign is named in memory of Bill Elliott's son, who was killed by a drunk driver after graduating from the U.S. Naval Academy in July 2000. "We are proud and honored to be part of the HERO Campaign's efforts to save lives by offering this DUI prevention simulator to high school students," Cape May County Prosecutor Jeffrey H. Sutherland said. "John Elliott would have served his country honorably as a naval officer had he lived. Now his legacy is saving countless lives through the HERO Campaign." The DUI simulator also has a distracted driving module which shows students how even a brief glance at their phone while driving can turn deadly. "We are excited to offer this next generation driving simulation to our driver education students," Ocean City High School Principal Wendy O'Neal said. "It will serve as a cautionary reminder for them to be safe and responsible drivers." NJM Insurance has provided funding for the simulator. "NJM is committed to supporting initiatives that help reduce the risks of teen car crashes and provide resources to encourage safe driving habits," said Erica Rosso, supervisor of the NJM Consumer Safety Partnership and Program. "We are honored to partner with the HERO Campaign to bring this innovative instructional tool to their driver education program." The HERO Campaign partners with high schools and colleges, bar and tavern owners, law enforcement, and NFL and Major League Baseball teams to promote responsible driving. More than 100,000 motorists have taken the campaign's online HERO Pledge to be safe designated drivers. The campaign has also wrapped police cars from 50 departments throughout New Jersey with its blue and gold symbol and message: "Be a HERO. Be a Designated Driver." Jersey shore weekend. 1. 2.
