Mary Schroeder (Molly), Ph.D. Clinical Psychologist

Certified Schema Therapist

Dr. Molly Schroeder, a psychologist, has been practicing Schema Therapy since 1994. Before she trained with Jeffrey Young, Dr. Schroeder was on the neurology faculty at Albert Einstein College of Medicine for 12 years conducting studies on aging and dementia. Now she divides her time between her private practices in Manhattan and New Rochelle.

I prefer the Cognitive and Schema therapies because we create a more collaborative relationship between the therapist and the client. While it is still a professional relationship, there is more interaction between therapist and client, and there is more emphasis on education. This helps promote trust in therapy and speeds up the healing process. This is one of the signature aspects of my approach, developing a sense of trust and collaboration. Trust facilitates change by holding the emotional process necessary for healing. Collaboration recognizes the client’s internal knowledge of what is needed.

Schema Therapy places emphasis on understanding how dysfunctional schemas were established and were necessary for survival early in life, compared to the schema dysfunction in the client’s current life. In addition, EMDR, hypnosis, meditation and mindfulness are techniques that are excellent for addressing current distressing emotional and personality problems.

I have found that people are surprised to find that healing is more of a “letting go” of dysfunctional patterns of thinking, feeling and behaving. The healthier patterns are needed but usually readily available. So healing is experienced more as relief, rather than the burden of more hard work.
