Donna Lettieri-Marks, PsyD

I see myself as a consultant or guide in personal growth–a consultant who is an expert in helping you through the change process. I am skilled in understanding the full range of human experience and relationships. I educate about available approaches and facilitate a process to restore optimal functioning, promote growth; and increase self confidence, happiness and a sense of fulfillment. I work well with both men and women in individual or couples counseling and psychotherapy. In relationship work I focus on educating couples and facilitating a co-creative process that restores and promotes constructive communication, effective partnering, and intimacy.
