Your Health and Well-Being in the Best Hands

Hi, I’m Dr. Leonidas Alevizos. I'm a general and digestive surgeon trained across Europe, now based in Seville.

I believe good surgery isn’t just about technique. It’s about people. About listening, understanding, and offering real solutions with clarity, empathy, and precision.

I’ve been operating for over a decade in Greece, Italy, Cyprus and Spain. My approach combines advanced laparoscopic and capillary surgery with something that’s often missing in healthcare: a human connection.

You're not just a case or a scan. You're a person with fears, doubts, and questions — and you deserve honest answers, explained in plain language, with time and care.

If you’re facing a procedure or have concerns, you’re not alone.


Let’s look at it together with calm, trust, and transparency.
