About Dr. de Marneffe
In over thirty years of practice, I have worked with persons of all ages who are seeking help
for a broad range of reasons. I use different therapeutic approaches, depending on your goals
and the challenges that bring you to therapy. Most people seek psychotherapy because they
feel unhappy or stuck and wish to change aspects of themselves and their lives. To grow and
change, it is important to first take an inventory of how things are now and the factors, both past
and present, that have brought you to this point. With greater clarity and awareness of your
psychological landscape, we will explore how to take steps toward living in a way that is most
true to yourself and your aspirations. I endeavor to build a collaborative therapeutic relationship,
founded on trust, curiosity and acceptance, which will enable you to learn about yourself, take
steps to grow, and will support you in moving in the direction of deeper meaning, connection, and
ease in your life.
