Dr.med. Helmut B Retzek

In the course of 20 years I have completed many, many, many, many, many trainings, really many courses!

Please take a look at the chronologically ordered trainings-list, you will be astonished, just as myself if I ever look at it. Seems kind’a crazy to do so many courses, but to study and to get more knowledge is our live and our holidays.
