Les Ottolenghi

EVP & CIO (former)

Les led the digital transformation efforts at Caesars Entertainment. His team's challenge was transforming a legacy architecture of point-to-point connections for over 800 fragile and end-of-life applications, with an average age of 18.1 years, into a cloud-first and mobile-ready digital ecosystem. With great planning, hard work, and strong execution, Les's teams delivered seven major technology transformations in 30 months, reduced enterprise systems to under 265, and helped Caesars increase EBIDTA while becoming the industry’s digital leader.
