Margie Casey began working for residential builders and commercial real estate developers in 1981. In 1998, she was named Small Business Person of the Year, by the Plantation Chamber of Commerce, for her business achievements and community service related to her 10 year retail and event business, an honor personally presented by former Governor Jeb Bush. High profile clients included the Florida Panthers, Plantation General Hospital, Starwood Hotels & Resorts and secret celebrities.

In 2006, she resumed her career in real estate obtaining real estate, appraisal and mortgage licenses, to deeper understand the home buying and selling process. Her analysis and marketing skills provide today's sellers and buyers with a strategic advantage. As Founder of Real Estate Scorecard, she has guided thousands of buyers through the relocation process since 2011 and continues to do so.

In 2016, she and her husband Dennis moved permanently to the Florida Keys, her childhood dream.
