My Philosophy

If there is an ultimate experience,
it is the journey of life

Each person is unique and valuable, shaped by their own biography, values, individual needs, perception and their attitude in interaction with the environment and fellow human beings.

It is important for me to join you in a work partnership defined by respect, transparency, authenticity and empathy.

My desire is to empower you to overcome stressful life situations. We work towards engaging the synergetic effect of resource activation, cognitive restructuring and disengaging limiting beliefs, as well as acquiring a positive attitude, and mindfulness to help you create well-being, happiness, and success in life.

… here, our work together begins. I look forward to meeting you!
