Seven area business leaders have launched Protege Executive Coaching and Consulting LLC to provide management consultation, the firm announced Monday. They have experience in a diverse group of fields, including financial/investment services, communications/technology, higher education, health care, marketing and communications, government relations, public accounting and nonprofits. Protege’s principals are Warren Green, former president and CEO of LifeBridge Health; David Nevins, founder of marketing and communications firm Nevins & Associates; Howard Rosen, president of RS&F, an accounting and consulting firm; Stephen Burch, board chairman of the University of Maryland Medical System and former president of the Atlantic Division of Comcast Cable; Joseph DeMattos Jr., CEO of Health Facilities Association of Maryland; Terrence Smith, an executive adviser and former higher education executive; and Judy Berman, former senior vice president of the Baltimore Sun Media Group. The firm’s offices are in Towson. A 2013 survey conducted by the Stanford Center for Leadership Development and Research found that, while nearly 100 percent of CEO respondents welcome being coached and receiving leadership advice, about two-thirds of them aren’t getting outside leadership advice.
