A day in the life of a power real estate broker who sells penthouses worth millions

• Leonard Steinberg is a New York City-based real estate broker and a president at Compass.
• Working mostly with units inside luxury buildings, Steinberg has been responsible for over $3 billion in transactions throughout his career.
• We followed Steinberg for a day to find out just what his work entails.

Compass President Leonard Steinberg has been responsible for more than $3 billion in transactions in his career as a real estate broker.

Luxury buildings are his specialty. His largest sale to date was on a Tribeca penthouse that sold for $43 million, and in 2009, he worked on the $32 million deal for Dolce & Gabbana designer Domenico Dolce's 11th Avenue penthouse.

Steinberg's move over to Compass - a real estate company that launched in 2013 and prioritizes data and technology - came as a surprise to many in the the industry. When he left Douglas Elliman, where he was the top agent for Downtown Manhattan, he told The Real Deal, "I like to feel like a bit of a maverick."

Earlier this month, we followed him around to see what a typical day in his life is like. Between countless meetings, apartment showings, phone calls, and marketing consultations, Steinberg keeps plenty busy.
