About Dr. Nicodemus, Clinical Psychologist

I am a clinical psychologist and psychotherapist with over 20 years of experience with diverse patient populations. My approach to treatment is based on my training in psychodynamic psychotherapy and psychoanalysis. 

I believe that when a patient comes to see a therapist, they often ask these questions: “Will I feel safe, will I be heard without judgment and can this unknown person be trusted?” The therapeutic relationship is the most profound, protected, and valuable asset created between the psychologist and the patient. I am in awe of my patients’ courage and their ability to trust, so that the issues grappled with can be explored and understood, and that ultimately they can begin to heal and grow in ways that are both needed and desired.
