My approach is rooted in a deep respect for each individual's unique experiences and circumstances. I use a variety of evidence-based therapeutic approaches, including cognitive-behavioral therapy, psychodynamic psychotherapy, and integrative psychotherapy, to address a wide range of mental health concerns, such as depression, anxiety, relationship difficulties, substance abuse, and addiction.

Consultation Services

In addition to my clinical practice, I offer consultation services to researchers, academics, and professionals seeking assistance with statistical analysis, research design, and writing. My expertise in research methods, statistical analysis, and writing enables me to provide high-quality support to individuals and organizations seeking to advance their understanding of the human experience.
