33rd Floor - Shane Tamura - Rudin Management Company: NYC Mass Shooting

Rudin Management Company, Inc., headquartered at 345 Park Avenue in New York City, is a prominent, family-owned real estate management and development firm with a legacy dating back to 1905. Founded by Samuel Rudin and his brothers in 1924, the company oversees one of the largest privately held real estate portfolios in New York City, managing 16 commercial office buildings totaling approximately 10.5 million square feet and 17 residential buildings comprising over 4 million square feet, including 241 residential units. Notable properties include 3 Times Square, the high-tech Dock 72 office tower at Brooklyn Navy Yard, and 345 Park Avenue, where the firm’s offices are located on the 33rd floor.

The company specializes in developing, owning, leasing, and managing both commercial and residential properties, with a focus on delivering superior client service and forging long-term relationships with tenants. Rudin Management is known for its innovative approach, including projects like the New York Information Technology Center at 55 Broad Street, the first fully wired office building in the world, and sustainable, contextually designed developments such as The Greenwich Lane luxury condo project. The firm has a history of pioneering urban development, having built New York City’s first post-World War II apartment building at 300 East 57th Street and contributing to iconic structures like 415 Madison Avenue and 80 Pine Street.

Led by Co-Executive Chairman William C. Rudin and Eric Rudin, Rudin Management employs over 700 workers and emphasizes sustainable, high-quality real estate advancements. The company also engages in civic initiatives, such as the Association for a Better New York, co-founded by Lewis Rudin in 1971 to support the city during its fiscal crises. Employees report a family-like culture with generous benefits, though some note challenges with nepotism and limited advancement opportunities.

In the context of the July 28, 2025, shooting at 345 Park Avenue, where Shane Devon Tamura carried out a deadly attack, Rudin Management’s offices on the 33rd floor were where the incident concluded with Tamura’s self-inflicted death. There is no evidence linking Rudin Management to Tamura’s motives, which centered on grievances against the NFL and claims of CTE, as outlined in his suicide note.
