Senior Executive Manager



For over 29 years, Tina Nardico Grayshaw has been on the front line of the Thomas A. Duke Company, where she’s served as a positive force for growth and change. Joining the company in 1989 as a receptionist, she quickly rose through the ranks to become its office manager. Seasoned in that role, she now manages a work environment of 30 employees, supervising all administrative staff and communicating skillfully to upper management the needs of employees. She also ensures that sales associates have the resources necessary – from market research and marketing plans to comprehensive listing materials – to conduct business smoothly. Licensed herself in real estate sales, she understands the business from the inside, and so she can effectively network with clients, too. In short, she is a Tina-of-all-trades at the Duke Company.

In addition to serving as office manager, Tina helped develop the company’s West Side Team, which specializes in all aspects of commercial real estate in southwest Oakland County and Livingston County. As a member of that team she oversees the research, marketing, and procedures for its listings, focusing especially on current market demands and how to help clients capitalize on them.

Beyond the office walls, Tina assists the CCIM’s Michigan chapter with educational events it brings to the state and organizes the Duke Company’s presence at the annual International Council of Shopping Centers convention.
