Founding Board Member Emeritus Recognized globally as a healthcare industry pioneer, Clayton McWhorter was as a charter member of the ProxsysRx board of directors — and served the company faithfully until the time of his death. “Clayton was truly a visionary, and we are honored to have had the opportunity to work alongside him. He was a trusted advisor, always bringing keen insights and new ideas to the table. He was also a treasured friend,” remembers ProxsysRx founder and CEO George B. Salem. “Clayton’s leadership and passion for improving the entire healthcare system distinguished him as a true game-changer. He was one-of-a-kind, and we are privileged to have known him. We miss him dearly.” McWhorter was Founder, Chairman and CEO of HealthTrust, Inc., and former Chairman of Hospital Corporation of America (NYSE: HCA). He retired as Chairman of HCA in 1996 to create Clayton Associates, a firm which invested in, and advised, entrepreneurs seeking to serve the healthcare industry. Another of McWhorter’s creations, HealthTrust, was a renowned healthcare industry success story. Under his leadership, HealthTrust took many of the smaller, less profitable hospitals within the HCA network, spun them off from HCA, and built them into profitable, sustainable community-based hospitals effectively serving communities around the country. HealthTrust later merged back into HCA. Prior to HealthTrust, McWhorter served HCA in a variety of executive leadership roles — including Chief Operating Officer and Vice President of Domestic Operations. Earlier in his career, he served HCA as a Hospital Administrator in various markets. McWhorter earned his B.S. Degree in Pharmacy from Samford University, where The McWhorter School of Pharmacy is named in his honor.
