Avalon Health Services has tapped Dr. Rahul Singal as chief medical officer. He joins the organization from population health firm ZeOmega, where he served as chief medical officer.

“For the past 20 years, I’ve been building technology to improve the health of large populations. Lab results for populations were always the elusive holy grail for me,” Singal said in a statement. “Now, here’s the opportunity to join this company that has been a leader in managing lab benefits with proven cost savings… Avalon’s innovation puts the patient at the heart of improving clinical outcomes.”
