Dr. med. dent. Jousef Siouri, M.Sc., M.Sc.
Master in implantology and oral surgery · Master in restorative and aesthetic dentistry

Studies and doctorate in implantology at RWTH Aachen, followed by several years in private practices in Germany and Switzerland. From this, an own approach has emerged: minimally invasive, biologically compatible and with the whole organism in view.
For every treatment the rule applies: you fully understand the diagnosis and your options before a decision is made.
«There are no standard solutions – only the solution for the person sitting in front of me.»

I had to have a tooth pulled yesterday and was understandably a bit anxious beforehand. But from the very first moment I felt completely taken care of. Mr. Siouri is extremely competent, works calmly and explains everything clearly. The whole practice team is also incredibly friendly, warm and attentive.

I already knew Dr. Siouri from when he worked at another dental practice, and I was very happy to follow him to his new practice. He isn’t just outstanding professionally, he also treats his patients with a lot of patience and empathy. The whole team is wonderfully friendly and very professional.
