About Stefan Sinn Group


Broker and Attorney


​​For Stefan Sinn, real estate is in his blood. Stefan literally grew up in the real estate business in his father’s real estate brokerage, and knows the business inside and out. He graduated magna cum laude from Florida State University’s Real Estate Program, a premier program consistently ranked among the top ten best programs in the U.S. Stefan also graduated 4th in his class from Florida International University College of Law and is a member of the Palm Beach County Bar Association.

​Today, Stefan is leading the Stefan Sinn Group, a team of highly trained real estate professionals assisting buyers, sellers and investors through their transactions. His real estate and legal expertise and extensive knowledge of the variety of challenges faced by his clients allow him to bring more to the table than an agent who simply knows the neighborhood. “Most of our clients are professionals in their industries. They seek expert advice regarding their real property transaction that will save them time, money, and aggravation.” Stefan Sinn Group offers its clients unmatched services like access to our full-time concierge assistants, access to the latest real estate technology platforms, and unique marketing programs.

​Stefan is heavily involved with the Young Lawyers Section of the Palm Beach County Bar Association. This group of attorneys organizes and hosts numerous events every year which raise tens of thousands of dollars for the benefit of local charities that are making a difference right here in our own back yards such as Friends of Foster Children of Palm Beach County, the Austin Blue Foundation, and the Legal Aid Society of Palm Beach County.

​Aside from his professional career and involvement with charity, Stefan enjoys spending time with his wife, Yissell, and son, Sebastian. The whole family enjoys traveling, barbecuing with family and friends, and pretty much anything outdoors.

​​With over 10,000 agents in Palm Beach County, making a sound decision can be difficult. Stefan Sinn Group makes the decision easy. Their professional team of staff and agents are eager to serve you.


Broker and Certified Luxury Home Marketing Specialist



Klaus commenced his real estate career in 1996. and received the rookie of the year award by Realty Executives in 1997 – his first full year in real estate. From there, Klaus rose quickly and became ranked as a top ten agent in Pinellas County in 1998, 1999, and 2000, before he opened his own brokerage where his son, Stefan, would ultimately begin work.

Klaus’ strength lies in his market-making ability. He has an almost magical ability to find the missing puzzle piece critical to create a deal where otherwise there would be none. One such example includes Klaus’ representation of a national hotel franchisee who required a higher net than the hotel’s financials supported. Within two years, Klaus strategically tied up all neighboring properties, solicited national retailers, and negotiated a substantial buyout for his clients. Other examples include configuring 124 parcels of land owned by sixty-four different international owners to complete a sale to a single buyer, and selling thirty-five separately-owned homes in just four days. Today, Klaus brings his market-making ability to high profile clients to structure transaction that make sense.
