100 Most Influential People in Healthcare - 2021

In addition to being recognized for its diversity, equity and inclusion efforts, Christus was busy partnering with Texas A&M to help strengthen the clinician pipeline, building a specialty pharmacy and new corporate headquarters.

Sadau joined Christus as senior vice president of patient and resident care operations, rising to senior VP and chief operating officer two years later. Sadau has more than more than 30 years of experience in healthcare operations and finance. He held multiple positions in the Adventist Health System before arriving at Christus.

If you have an emergency and need to be on your phone, you declare it at the front-end.”
