Asma Atfeesh
I don't know what to say. First of all, I would like to thank Dr. Marwan for his advice and treatment. Before I visited the clinic, I was suffering from left shoulder pain that I can't sleep at night, after I got a treatment I feel much better and no pain anymore.
Also, many thanks for all staff and his nurse.
Mohamed Binsafwan
Professor Sillem was the first doctor to diagnose my endometriosis and removed it surgically. I was pleasantly surprised by the success of the surgery, especially on my bladder.
During a laparoscopy, a septum was also discovered and removed in a separate operation. This procedure, too, was performed very well in my opinion.
Professor Sillem consulted me thoroughly before each operation, and I felt I received excellent medical care.
Clara Hoffmann
Went for lipoma removal and had been a great experience: Dr Bayer and his staff are the perfect surgical partner and care advisor. Highly recommended. The actual intervention and the followup were very smooth and worry-free. Thank you very much indeed.

Samer Othman
Prof. Dr. Sillem operated on my bladder for endometriosis for the first time in the fall of 2016, and in early March 2025, he removed my uterus. I feel very well looked after by him – he takes his time, listens, and addresses my concerns. The aftercare for both surgeries was also excellent – he checked on me several times after the surgery. I always feel in good hands with him; I highly recommend him!
