This week on the Business Brush, Nick sits down with Mark Lipton of Tremont Paint the 112-year-old New York paint store founded by his great-grandfather. He likes to say he's been in the business full-time for 31 years, but he never new a life without the paint store. In addition to running those stores, Lipton spent more than 20 years as a contributing columnist for Paint Dealer Magazine and now blogs and podcasts under the title Mark My Words.
