My wife found a brain tumor last year. The neurosurgeon himself in our hospital recommended to go to Germany if there is an opportunity and recommended the clinic Zolingen. We are convinced that we need to be treated there. We were in the best clinic in Germany. Personally, Dr. Boole operated on and monitored the condition of his wife after surgery for a week. We were lucky and the tumor turned out to be benign, and no subsequent treatment was required. The clinic has employees who speak Russian. They helped us a lot. Special thanks to them. I think we are lucky. I recommend this clinic.
