George built his career on a conviction: if something feels wrong, it deserves investigation. Not in six weeks. Not after a referral chain that passes through three departments. Today. With the results explained to you face to face by the person who performed the test.
That conviction led him to incorporate Medical Diagnosis Ltd on 23 April 2006 and, later, Victoria Medical β a place where a patient can walk in with a worry and walk out with a clear answer, because the GP, the blood lab, the ultrasound suite, and the specialist are all under one roof.

Patient Experiences
"Dr Xynopoulos found a valve issue my NHS cardiologist had been monitoring with a 'wait and see' approach for years. He explained everything on the screen as the echo was happening and gave me a clear management plan before I left."

"I was terrified before my heart scan. George put me completely at ease within the first two minutes. He answered every question, showed me what my heart looked like on the screen, and walked me through the results in language I could understand."

"Excellent cardiologist. Thorough, unhurried, knowledgeable. The fact that he performs and interprets the echo himself rather than sending you off to a technician makes a real difference. You feel like you're in expert hands."
