Kairos Longevity Clinic

Care starts with a clinician-led intake that maps the patient's goals to the right specialty path, then layers in Metbalance, hormone or biomarker testing, and in-clinic therapies as needed. The subscription credits are meant to keep follow-up attached to the plan, so the visit feels less like a single appointment and more like an ongoing optimization relationship.

• Integrated but still personal. Kairos brings physicians, nutritionists, sleep medicine, women's health, and regenerative aesthetics into one small Madrid clinic rather than splitting the experience across separate offices.
• Credit-based membership model. The monthly tiers bundle consult credits and treatment discounts, which is unusual in a Spanish private-medicine market that often bills per visit.
• Founder-shaped aesthetic and longevity posture. Castillo's regenerative aesthetic background gives the clinic a visible emphasis on subtle facial rejuvenation alongside internal health optimization.

• Membership is the access model. Credits can cover consults and discounts, but procedures and advanced treatments may still bill separately.
• Self-pay posture. Standard Spanish private insurance generally does not cover the diagnostics or treatments; Kairos supplies reimbursement paperwork when a patient wants to submit a claim.
• Spanish-first operation. The website and most public materials are in Spanish. Confirm English availability when choosing a clinician.
• Plan for Chamberí. Most care requires an in-person visit to the Madrid clinic.
