“Back in 1981, I didn’t even know what $1.3 billion was,” Weiner quips. “But I always knew I wanted to build something.”

Over the decades, Weiner redefined what it meant to lead in public accounting, emphasizing trust, talent, and strategic growth. Rather than micromanaging, he viewed his role as “architect,” guiding the firm’s culture, empowering top-tier professionals, and letting his team do what they did best. “If you’re the smartest person in the room, you’re in the wrong room,” he said.
