AdventHealth has named Mark Smith president and CEO of AdventHealth Littleton, effective Jan. 25, 2026. He will report to David Weis, AdventHealth Rocky Mountain Region’s newly appointed president and CEO.

Smith most recently held the role of president and CEO at AdventHealth Avista, where he has led with a steady focus on people and purpose, helping position the organization for continued growth and service to the community. Prior to AdventHealth, he served in executive roles at MultiCare in Washington and previously with Kettering Health Network in Ohio.

“Mark consistently recognizes and supports caregivers and leaders who live out our mission of Extending the Healing Ministry of Christ, helping patients and families feel supported and cared for in body, mind and spirit. I am grateful for the impact Mark has made at AdventHealth Avista and look forward to his continued success at AdventHealth Littleton,” said Weis.

Together with the Avista team, Smith has supported several significant milestones, achieving strong clinical outcomes. His team was recognized with consecutive CMS 4- or 5-star ratings, Leapfrog A safety grades and top-quartile mortality rankings by Premier Inc.

“I’m excited to join the AdventHealth Littleton team and work alongside the caregivers and leaders who serve patients and families every day,” said Smith. “I look forward to listening, learning and supporting the team as we continue living out our mission together.”

Smith holds a Juris Doctor from the University of Nebraska College of Law and a Bachelor of Science in accounting from Union Adventist University.
