I am also the PR, Marketing and Social Media Director for my husband's group of companies, Highland Strategic, LLC, which he has been running and growing since leaving the Wharton School in the late 1990s. The companies cover a wide range of activities in North America and South America/Central America, as well as starting to grow in Europe and Asia. In my work for his companies, at last count, I believe I manage over 40 social media accounts, among numerous other marketing and PR activities.
