Carol & Ed Williamson with son Trae.

The Williamson family will soon be celebrating 50 years in their highly successful and award-winning dealership, Williamson Cadillac Buick-GMC. Renowned for their excellent customer service, the Williamsons are also known for decades of philanthropy and service to the Miami-Dade community.

The automotive industry is a family affair for Ed and Carol Williamson and their son, Trae, the fourth generation in the business. It began with Ed’s grandfather who opened a Hudson-Packard and International Harvester dealership in Indiana in 1929. In 1945 Ed’s father, George became partner in the company and then moved to Lake Wales, Florida, opening a Cadillac-Oldsmobile dealership in 1954. George Williamson sold this business in 1967 and moved to Miami where he opened another dealership.

In the 50s and 60s, Carol’s father purchased his Cadillacs from George, making the trip from Miami to Lake Wales. The two men became friends over the years. Eventually, Ed was introduced to Carol and they soon began dating. For 48 years they have been partners in life, marriage, and business.

Williamson Cadillac was located on Kendall Drive across from the Dadeland Mall from 1967 until 2001 when it moved to its current facilities on 104 Street and US1.

Williamson-Cadillac--4Ed (Chairman and CEO) is a graduate of Auburn University with a Bachelor’s degree in Aerospace Engineering. In 1967, the same year he graduated, he started training in the automotive business and attended the General Motors Institute in Dealership Management. Ed and his brother would work together with their father, eventually buying him out in 1976; Ed’s brother retired in 1998, and Ed purchased his brother’s share of the business, too.

One of the most respected community leaders in Miami, Ed continues to serve a number of professional organizations concerned with General Motors and Florida dealership associations. He has been a Trustee of the University of Miami since 1980 and serves or has served on other boards such as Northern Trust Bank of Florida, N.A., American Bankers Insurance Group, Av-Med Health Plan, University of Miami, Orange Bowl Committee, Greater Miami Chamber of Commerce, the Beacon Council, South Miami Hospital, Rotary Club of South Miami, Dade Foundation, and the United Way of Dade County, among many others.

Awards are showcased throughout the facilities.

Ed has also received significant community recognition and many awards, among them awards for excellence in the business and awards for public service such as the University of Miami Honor Society (1991), University of Miami Vice President’s Award for Service (1992), Florida Education Foundation Business Award (1995) and Ronald McDonald House Twelve Good Men Award (1999).

“We’re a family here. We touch each other’s lives like family should.” Carol Williamson.
