Joel Saul Wiener (born 1948/1949) is an American real estate developer and landlord, and the CEO of Pinnacle Group.
[4] Through his company, Pinnacle Group, Wiener manages about $2 billion worth of New York City property, 10,000 apartments, almost all rent-regulated, in every borough except Staten Island.
[5] Pinnacle has had extensive funding from the Praedium REIT, including the purchase of Baruch Singer's nearly 3,000 apartments in northern Manhattan for $500 million.
[5][6] In October 2022, it was disclosed that the State of New York obtained a settlement with Wiener, where the CEO admitted to state Attorney General Letitia James’s office that Wiener's company had failed to properly acknowledge the capital repairs necessary for gas piping when selling units in the converted Forest Hills condo.
Pinnacle agreed to pay $1 million to 300 tenants to make up for what they’d been overcharged, with interest.
