“I am very grateful to the leaders. They are extraordinary women with wisdom, intuition and huge hearts…I watched them work with people who have experienced terrible trauma with a special ease, presence, empathy and with no judgement whatsoever.” E.M

I am a social worker and a psychotherapist and have been practicing Core Energetics for  the past 20 years.  I have a private practice in New York City, working with individuals and groups. My fascination with the role of the body in human psychology started about 30 years ago. As a college student I participated in some of the very first bioenergetics workshops in Poland. In 1993,  I started my training at the Institute of Core Energetics in New York City.   In 1995 I became a personal assistant for the creator of Core Energetics – John Pierrakos MD, and I worked with him very closely until his unexpected death in February 2001. My work with Dr. Pierrakos was an extraordinary experience that changed my life.  It was a unique way to experience Core Energetics in its most original form. After finishing my training I worked for years at the New York Institute, teaching, supervising and leading groups.

Core Energetics dramatically changed my life, and every day I witness how it brings profound changes to the lives of my clients. Teaching Core Energetics in Poland is both a privilege and a duty. It is certainly the biggest challenge I have undertaken in my life.
I enjoy sharing my experience and knowledge with our students, this gives me deep joy and sense of fulfillment.

I have worked as  a psychotherapist and social worker since 1988, treating  individuals, couples and groups .  I am also a Teacher and Supervisor for the  New York Institute of Core Energetics along with being a guest teacher at the Core Energetics Institutes in Holland, Mexico and Canada.

As a therapist and teacher of Core Energetics, I have had many opportunities to witness the important and courageous changes my clients and students make to give their life more meaning.

Poland, the homeland of my parents, is a country and culture that my heart and soul are deeply connected to. For a long time, my dream was to bring the work of Core Energetics to my ancestral home. Now that we have started a Four year training program, it is so exciting to be teaching the future Polish speaking Core Energetics Therapists.

Core Energetics is one of the things which gives my life meaning. This method itself is alive and I see it as a useful map full of knowledge which gives people support to see and face their inner truth. What I love about it is the connection between spirit and body and  how it is an excellent form for working in the present moment.
