My impression of the Core transformation cannot be described in words... as well as the commitment, knowledge, expertise, intuition of Iskrica Zdenka Knežević in guiding you through this magical process, after which you seem to wake up in a new fulfillment and a more beautiful world... I have been in the last 13 years to many different educations and treatments with different techniques for working with the subconscious....

The Core technique is the most comprehensive, the most effective, the fastest and best results... after each session I felt like I was on a cloud... as if all the mud and residue is washed away from your soul, and you get joy, clarity and new insights. .. I was also fascinated by Zdenka's skill in leading this process - while I wandered through the labyrinths of the subconscious in which she introduced me, she knew exactly which way to lead me, to direct me to a way out and a solution, asking the right questions ... I simply have no explanation for such intuitiveness, clairvoyance or God's gift, whatever it is, but above all it is unconditional love and dedication to the client and determination to achieve results.... I am now quite a different, more successful, more satisfied and happier person compared to the one before. .B.B
