4/10 Thank you to our employees, faculty, volunteers, donors and supporters for making that happen. Over the past nine years, it was your work that truly transformed UT MD Anderson's culture and capabilities into what we experience and see today.

3/10 When I interviewed with the @UTSystem Board of Regents for this role, they asked what the institution needed most. I told them: transformation.

2/10 While it was a wonderful way to close this chapter of my career, it truly was a way to honor our more than 27,200 teammates and all that we accomplished together.

I was blown away by how many @UTMDAnderson teammates gathered to celebrate my nine years as president and more than 30 years of service to this unbelievable organization. I will always remember it. #EndCancer #thread 1/10
