Ms. McKinney is a life-long entrepreneur and community leader. She started her first landscape business at the age of 12 and at the age of 19 while in college, she launched a leaf clean up service that became a full services landscape company two years later. Delores held several progressively responsible positions with Johnson Controls Automotive Division including Chemist (1991) and Cost Analyst (1996).

That business grew and evolved into the successful government contracting firm that it is today and was renamed Eminence Group, LLC. in 2006. Because of the excellence and integrity associated with the company's name and its leadership, major corporations such as Gilbane Building Company and Harkins Builders have engaged Ms. McKinney (and Eminence Group) as their desired Small business partner.
