Dr. Tamsin Lewis

Dr Tam is an integrative physician and founder of Wellgevity, working between the UK and Ibiza. A founding member of RoseBar Longevity at Six Senses Ibiza, she pairs rigorous diagnostics with trauma-informed, nervous-system-aware care. She resists protocolised medicine; plans are co-created from objective data, clinical judgement and lived context. Her BioHarmony framework maps regulation, rhythm, metabolic steadiness, inflammation and connection, allowing progress to be tracked pragmatically—trends, not single numbers. A former Ironman champion, and someone who has recovered from significant trauma and illness, she brings grounded empathy and disciplined realism to every case. Her scientific interests centre on systemic endocrinology and **neurohormonal systems medicine**—how mind, brain and hormones shape healthspan. Precise about mechanisms, transparent about uncertainty and careful about safety and trade-offs, she treats longevity as the by-product of restored vitality. She also leads concierge programmes, retreats and education to build literacy and agency.
