Stellar Management, a New York City-based real estate developer and operator, was founded in 1985 by Laurence 'Larry' Gluck and Steve Witkoff. Based in Manhattan, the firm is fully integrated, combining development, investment and management in-house. It oversees a portfolio of over 12,000 rental apartments and roughly three million square feet of commercial space across about 100 buildings, primarily in Manhattan but also in Brooklyn, Queens, the Bronx and Westchester County. Its rental offerings range from renovated prewar walk-up and brownstone buildings to modern mid-rise and high-rise towers in neighborhoods like the Upper West Side, Tribeca and Harlem. Many Stellar properties feature upscale amenities—such as 24-hour doorman service, fitness centers and landscaped rooftop lounges—reflecting the company's emphasis on community-oriented, amenity-rich urban living.

Beyond apartments, Stellar's portfolio includes substantial office and retail space, often integrated into larger mixed-use developments. For example, Independence Plaza at 310 Greenwich Street in Tribeca is a mid-1970s three-tower rental complex whose on-site amenities—such as an indoor pool, children's playrooms and on-site laundry—illustrate the company's practice of modernizing older buildings with contemporary conveniences. The company takes a long-term, community-focused approach, frequently renovating aging properties and creating communal spaces to enhance neighborhood vitality. As a result, renters in Stellar-managed buildings enjoy modern amenities and stable, community-oriented living, aligning with the company's vision of sustainable, future-ready urban housing.
