Daniel Heider

For nearly two decades, many of Washington’s most consequential families have entrusted their most significant real estate decisions to Daniel Heider and The HEIDER Company.

Over that time, Daniel has built an advisory practice distinguished not simply by its production, but by the precision with which it was assembled. Every advisor, every specialist, and every member of the broader practice reflects a singular philosophy: that the client experience at the highest end of the market should be met with an equally exceptional standard of judgment, discretion, and counsel.

As Founder and CEO of The HEIDER Company, and the youngest Executive Vice President in the history of TTR Sotheby’s International Realty, Daniel has led his practice to the #1 ranking in sales volume companywide for six consecutive years. Recognized by RealTrends and The Wall Street Journal as the leading residential real estate practice in the Capital Region across all practice sizes, The HEIDER Company is also ranked the #2 residential real estate practice worldwide by sales volume within Sotheby’s International Realty, with more than $540 million in closed sales in 2025 alone. Daniel was named to the Washington Business Journal‘s Power 100, recognizing the region’s most influential business leaders.

Few careers in Washington residential real estate have been defined by as many market-defining transactions. With more than $3 billion in career sales, Daniel represented the historic sale of 2400 Foxhall Road, then the highest residential sale ever recorded in Washington, D.C., before surpassing that benchmark with the $28 million sale of Halcyon House, which remains the highest residential sale in the city’s history. Through HEIDER Private, the practice’s platform for confidential transactions, Daniel has also advised on hundreds of millions of dollars in off-market sales for many of the region’s most prominent families.

What has always distinguished The HEIDER Company is not only the caliber of the properties it represents, but the sophistication of how those properties are introduced to the world.

The HEIDER Company has become the world’s most followed residential real estate practice on social media, reaching an audience of more than 4.5 million and generating more than three billion impressions across 142 countries. The practice’s work is regularly featured in The Wall Street Journal, The Washington Post, Forbes, and Architectural Digest, reflecting a platform whose influence extends far beyond Washington.

A fifth-generation Washingtonian and longtime Cleveland Park resident, Daniel’s connection to the city extends far beyond his profession. He serves on the Board of the National Symphony Orchestra and actively supports N Street Village, SMYAL, DC Central Kitchen, and St. Jude Children’s Research Hospital.

Today, The HEIDER Company continues to advise many of the region’s most prominent individuals, families, and institutions, combining discretion, strategic counsel, and global reach in the representation of Washington’s most significant real estate.
