I hold a full professorship in graduate business studies at an online university where I teach MBA and DBA students in strategy, entrepreneurship, making breakthroughs, and marketing. I am the author or a coauthor of seven business books, including a global bestseller. My specialties are adding and retaining customers, acquisitions, business model development, cost reductions, developing new offerings, entrepreneurship, leadership, management, market research, problem-solving, project management, reducing investment needs, stock-price improvement, and strategy. I bring a lot of practical knowledge to your business subjects and issues. From these perspectives I can help you grasp case studies and paper topics at a more fundamental level.
