LifeSpan Medicine
A Santa Monica practice on Wilshire Boulevard that has been doing preventive and functional medicine since 1992, long before anyone called it longevity. Dr. Chris Renna founded it and still leads the flagship program. The range is unusually wide for a concierge practice: full-body MRI, microbiome work, hormone and peptide protocols, plasmapheresis, and a regenerative sports-medicine arm doing Regenokine, BMAC, A2M and PRP injections for joints and spine. The Platinum program is the top of it, an annual longevity program capped at 75 clients that includes a functional brain MRI and cognitive-risk labs, and which you can only join if an existing client refers you. Nothing is priced anywhere on the site. The practice publishes a team on its own pages and the LifeSpanMD network publishes a different, larger one, and neither says who works in Santa Monica as opposed to Dallas or Miami.
The care team
Who would actually see you, and what they trained in.
LifeSpan Medicine runs three offices, Santa Monica, Dallas and Miami, and publishes its clinicians centrally rather than per office. Nobody is assigned to Santa Monica on any page we could read. Two rosters exist and they do not match: the practice's own team page names these five, 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. The practice's own page is used here because it is the practice's own site; ask who you would actually see at Wilshire Boulevard.

What this clinic can help you evaluate or manage
Plain-language goals come first. The clinic’s named tests, treatments and programs stay below for people who want the technical detail.
LifeSpan calls itself integrative and functional and its physicians publish Institute for Functional Medicine training, root-cause framing and nutrition-led plans. But a large part of what it sells is procedural: Regenokine, BMAC, A2M and PRP injections, plasmapheresis, shockwave and laser. Both halves are the clinic's own description of itself.
Establish where you stand today, before symptoms show up.
The concierge program is built on comprehensive medical evaluations with full-body MRI and laboratory work, run by a practice that has been doing this since 1992.Find cardiovascular risk years before an event.
Cardiovascular health and function is named among the issues the practice addresses, and Platinum describes reducing cardiovascular risk with what it calls cutting-edge diagnostics.Set a baseline now so change is detectable later.
The Platinum program includes a high fidelity functional brain MRI and laboratory panels for cognitive risk, and the practice separately publishes EEG and neurological assessment.Investigate persistent gut symptoms with real testing.
Microbiome analysis is published as a core diagnostic, and the Platinum program is described as focusing on the microbiome and gut alongside detoxification.Give unresolved or multisystem symptoms a longer, coordinated workup.
Immune health, detoxification and cancer recovery are named among the practice's stated areas, and Platinum describes reinforcing the immune system as one of its four focuses.Services explained
Plain-language groupings help make different clinic service menus easier to understand and compare.
Diagnostics
The testing layer. Note what is here that most concierge practices do not carry: a functional brain MRI paired with cognitive-risk bloodwork, which is a specific attempt to baseline your brain rather than a general scan.
Hormones, nutrition and prescribing
The prescribing side, run out of a functional-medicine frame. Hormones and peptides are described as personalised protocols rather than a fixed program.
Regenerative and musculoskeletal
The sports-medicine arm, and the reason people arrive here with a knee rather than a lab result. Regenokine, BMAC, A2M and PRP are injection treatments for joints and spine, and the evidence behind them is thinner than for the diagnostics above.
Cellular therapies
Plasmapheresis filters and replaces blood plasma. It is established treatment for specific autoimmune and neurological conditions and experimental as a longevity intervention, and LifeSpan sells it in the second sense.
