LifeSpan Medicine

Santa Monica, Westside · Concierge preventive and functional medicine practice

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.

Medical leadership is published by LifeSpan Medicine, not for this location.
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.

Start with the outcome

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.

Care philosophy Integrative & root-causeRegenerative & interventional (secondary)

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.

01
Whole-body baseline

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.
02
Heart & circulation

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.
03
Brain & cognition

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.
04
Gut & digestive health

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.
05
Immune, inflammation & complex symptoms

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.

What they do

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.

Personalized hormone replacement therapyPeptide protocolsPrecision nutrition and lifestyle medicineIV therapy

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.

InsuranceNot published. Nothing on the home and about page, the team page, the services page, the Platinum page, the concierge page or the contact page says whether LifeSpan bills insurance, stays out of network, or gives you a superbill. The contact page carries three addresses, three phone numbers and an enquiry form, and nothing about payment. Ask before you sign.Confirm coverage and reimbursement requirements before booking.
TelehealthNot published as a named service. The practice publishes 24/7 access to your medical team, without saying whether that includes video visits.Availability can depend on the service and patient location.
Accepting patientsNot published. LifeSpan publishes "access to your medical team 24/7" as part of its concierge programs, but no opening hours appear anywhere on the site, including the contact page.Contact the clinic to confirm current scheduling.

The Miami street address is left out because LifeSpan's own pages disagree: the network page gives 1001 Brickell Bay Drive #2402, while the practice's contact page prints 100 SE 2nd St #2220 in text and links a map to 1001 Brickell Bay Dr #2402.
