My name is Petra Doubkova and during my 45 years of life I have found the path to health. Since it is said that the body follows the mind, I am fully engaged in psychosomatics, that is, by connecting body, soul and mind.

Simply put, I will never look at you based solely on what is currently bothering you. I see every person as a complex being.which you deserves attention how to physical, so on psychic and mental level.
