It was a beautiful day today! I mean it just like that!!! No swelling, no pain, and no painkillers. Thank you so much! Just your time and sensitivity at T1, all the education and care beforehand and the humanity you have shown has given me complete confidence and I am already looking forward to T3.

Even I, as a confirmed sceptic, have now been convinced that it's not all scams, overcharging and rip-offs. What you get with Dr. Leu and his team is really absolutely perfect.

From the first email to the last appointment, everything was well thought out and perfectly organised. I felt in good hands and for me there is no question, if I had to make this decision again, I would do it just like that.
