LifeSpan Medicine
LifeSpan Medicine is a concierge preventive and functional medicine practice in Santa Monica, in practice since 1992. Founder Dr. Chris Renna leads its Platinum program, an annual longevity program capped at 75 clients and joined by referral. Diagnostics run from full-body and brain MRI to early cancer detection, alongside hormone therapy. People come here for a whole-body baseline and early cancer screening.
The care team
Every clinician the operator publishes by name, with their role exactly as the operator states it.
LifeSpan Medicine runs three offices, Santa Monica, Dallas and Miami, and publishes its clinicians centrally rather than per office. No page assigns a clinician to Santa Monica. Two rosters exist and they do not match: the practice's own team page names these two of them, while the LifeSpanMD network page for the same practice names Dr. Chris Renna, Dr. Olivia Lesslar, Dr. Karen Koffler, Dr. Paris Whitney, Dr. Melissa Sundermann, Dr. Moshe Ben-Roohi and Dr. Mary Dohrmann. Only Dr. Renna and Dr. Ben-Roohi appear on both; ask who you would actually see at Wilshire Boulevard.
