Robbie Briggs
President and CEO

His understanding of design, structure and spatial potential combined with integrity and business acumen has served him well in sales since 1980. Now President and CEO of Briggs Freeman Sotheby's International Realty, he is the second generation to give the Briggs name to one of the leading brokerage firms in Dallas for quality residential property.

Robbie, his wife, Nancy, and their two youngest daughters lived in Beijing, China, for almost three years. China offered opportunities for growth for the entire Briggs family, both personally and professionally. He continued as a chief executive overseas, whose dedication to Dallas remained uninterrupted through his continued service to his firm as well as to various educational and non-profit boards.

He is a strong believer in supporting the community and has become well known in the public and private sectors. Over the years he has been chairman of the Presbyterian Hospital Foundation, the Juvenile Diabetes Foundation and The Cambridge School of Dallas Board. He also has served on the boards of the Hockaday School, the Park Cities YMCA, the Chemical Awareness Council and on the Tartan board for Scottish Rite Hospital. Briggs served as HPISD Dad's Club President and on fundraising committees for his alma mater, St. Mark's School of Texas. He and Nancy are active participants at Reunion Church, a multinational non-denominational body located in Downtown Dallas that is committed to urban outreach toward the minimalized and homeless community in the city.

Gene Taylor
Executive Vice President
Director of Sales and Agent Development

Gene Taylor brings strategy and innovation to the selling and negotiation process in his leadership role at Briggs Freeman Sotheby's International Realty. Since joining the company in 2011, Taylor has recruited top agents specializing in prime neighborhoods. He has helped the company grow annual sales from $600 million to just under $2 billion, making it the top luxury real estate firm in the area with the highest producing sales associates per capita in terms of production of any firm in the Metroplex.

“We have great success stories of agents joining our company and maybe closing $5 million in sales, who went to $10 million the next year and $30 million or $40 million the following year,” says Taylor. “If that is your goal, to take your business to the next level, we have the proven track record to get you there.”

Taylor’s working style involves directly interfacing with agents, whom he inspires and motivates so their business will grow. Taylor also is known for creating an office environment where every agent is the best that he/she can be. His ultimate goal is to ensure that clients receive extraordinary service.

“If your goals match our strategy, with our culture, it’s a win-win,” he says. 

Taylor’s deep roots as a native Texan support his continued success in real estate. Born in Hillsboro and raised in Corpus Christi, where he learned the love of sailing and all things related to water, his hard work and talent for fund raising have benefitted the Junior League of Dallas, the Park Cities YMCA, the Muscular Dystrophy Association, the Leukemia and Lymphoma Society and Phi Gamma Delta.

With a degree in accounting from Texas Tech University, Taylor has brought his ease with numbers to the business of real estate. Earning his residential sales license in 1985 and his broker’s license in 1988, he has been immersed in Texas real estate ever since.

Taylor's commitment to the industry is exemplified by his extensive involvement in the MetroTex Association of Realtors. Rising through the Government Affairs and TREPAC Committees to the Board of Directors, he served as President of the Association and holds the unique honor of receiving the Association's two highest awards: The Lois Hair Bernays Award as Salesperson of the Year and the Easterwood Cup as Realtor of the Year.
