Joel Wiener

Career The family firm, Arthur Holding Company, purchased New York buildings in the 1970s and 1980s.

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.

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. This was not the first time that the Pinnacle Group has come under legal scrutiny. Over the course of a 2006 investigation, the company — which owned 20,000 apartments in New York City at the time — conceded that it had overcharged rent-stabilized tenants at an apartment complex in The Bronx. Pinnacle agreed to pay $1 million to 300 tenants to make up for what they’d been overcharged, with interest. The company also agreed to “retain a forensic accounting firm to review rents charged on all of its properties in New York City.”

Personal life Wiener is married, with a daughter, and lives in Woodmere, Long Island, New York.
