| M1 | Specialist certification of the responsible physician Found; specialty adjacent to what is advertised (noted on the profile). GMC Specialist Register: plastic surgery, entry from 11 Jul 2000, matching the clinic's plastic surgery focus. The GMC record is held as "Ioannis Alexandridis"; the clinic's own site spells the surname "Alexandrides" and the first name as the Greek short form "Yannis" — first name, specialty and registration period are otherwise consistent with the clinic's own biography of its founder.
