Editorial note: VERIFIED Tier 1: CEO Kapp, CMO Dawn Mussallem (DO), and co-founder Diamandis all confirmed CURRENT on the live fountainlife.com/about team page; all 3 headshot URLs return live image files (HTTP 200). CORRECTION/FLAG: Helen Messier (originally listed as Chief Medical/Scientific Officer) is NO LONGER present anywhere on the current team page — DROPPED as a current principal (likely departed; do not advertise her). Reviews are thin in count (concierge model) but corroborated across Google, Birdeye, BBB, Yelp, Glassdoor. Glassdoor shows critical EMPLOYEE reviews (revenue-first culture, provider reimbursement complaints) — not patient-facing but worth noting. Not BBB-accredited (registered only).
