A Word from our founder, Dr. Lisa Williford
“For the past 17 years as an Emergency Medicine physician, I have cared for thousands of patients in critical moments. I also saw many who weren’t in crisis but felt unwell— experiencing fatigue, weight changes, sleep or mood issues, or declining strength despite “normal” tests.
This led me to ask different questions: What changes are we missing before disease is diagnosed? What can I identify and do now to improve long-term health and function? Why do patients have to wait until they are sick to find an label or a treatment for their symptoms?
I founded Selah Longevity, Health & Medicine to give those questions the time they deserve. Selah is a physician-led concierge practice focused on careful evaluation, patient education, and evidence-based prevention to help patients understand their health and make informed decisions. My mission is to give patients a clear understanding of their health, address modifiable risk factors before they become obstacles, and create tangible strategies for their pursuit of lifelong health and function.”
