Therapy Practice

“I believe taking a collaborative and introspective approach to treatment helps patients access their own wisdom and healing potential.”

About us

I provide a collaborative space to explore your inner world together. As a clinical psychologist, I help you uncover your own wisdom and healing potential. We'll use careful introspection to make sense of your experiences and patterns. This approach is ideal for those ready to look inward and actively engage in their well-being. Together, we identify your strengths and develop practical ways forward for lasting change.

Approach

We work side-by-side, using quiet reflection and focused questioning to help you notice patterns beneath everyday troubles. In our Mount Kisco office, in English, sessions move at a measured pace—close listening, thoughtful reflection, and practical experiments between meetings—so insights become manageable steps. For adolescents, parents, couples and individuals grappling with trauma, mood or relationship strain, this translates into steady mapping of feelings, memories and choices. People who want an inward, engaged process often find this way of working supportive.
