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.

⭐⭐⭐⭐⭐ I have been operated on twice by Dr. Alevizos, and without a doubt, he is a great professional who is caring and deeply involved with his patients. I felt absolute peace of mind in his hands. Thank you for everything, Dr. Leonidas!
Francisco J
⭐⭐⭐⭐⭐ Without a doubt, Dr. Leonidas is a spectacular surgeon, in addition to providing gentle, kind and reliable treatment. I was lucky enough to be operated on by him for a pilionidal cyst after having previously been operated on twice without obtaining good results... until I put myself in the hands of Dr. Leonidas, who thanks to his intervention after almost two years, I am in perfect condition. been and I haven't had any problems again!

⭐⭐⭐⭐⭐I had stomach surgery by surgeon Leonidas Alevizos and noone can imagine the great quality of life he gave me. His history with me was always his absolute concern for my digestive problems and there was not a single consultation in which I did not feel understood or supported. His psychology with me was excellent, my post-operative period was very monitored by him and I could not have felt more cared for at the time when I felt most vulnerable.
