Jessica Sitomer President, The Greenlight Coach, is another regular on The Buzz. This week, we wanted to spend a bit more time talking with her — about the business of running a business. Specifically, how to successfully run a virtual office. How and when should you do sales calls? What type of communication works the best? What’s the most effective relationship to have with a client? How do you stay focused when you are constantly traveling? As always, Jessica has great ideas and tips to share with all of us.
