In addition to his general practice, he maintains a psychodynamic psychotherapy panel where he helps patients explore developmental and relational patterns that contribute to their symptoms. His specialties include treating depression, anxiety, adjustment disorders, PTSD, insomnia, bipolar disorder, and ADHD.

Follow-up visits typically last 20 to 30 minutes, focusing on assessing treatment progress and making necessary adjustments.
