BASKING RIDGE, N.J. – Avaya, a leading global provider of business communications applications, systems and services, today announced that President & CEO Lou D'Ambrosio will be stepping down for medical reasons. 


"Lou has been a guiding force at Avaya during his six-year tenure, the last two as CEO," said Dave Roux, co-founder of Silver Lake and non-executive chairman of Avaya. "He has shaped a compelling strategy, built a strong team, and led the company through important technology transitions to market share leadership. We cannot thank Lou enough for his tireless leadership and inspiration, and we know he will attack this personal challenge with the same winning spirit and determination he has brought to the toughest business challenges." 


"It has been a true privilege to serve the customers and team of Avaya," said D’Ambrosio.
