Meet Dr. Domenick Tirabassi
Domenick Tirabassi, PsyD (he/him) is a licensed clinical psychologist and the Founder & Clinical Director of Tosa Psychological Services. In addition to leading the practice, he maintains a select clinical caseload focused on trauma treatment and its impact on emotions, relationships, and long-term functioning.
His work is grounded in EMDR therapy and relational psychotherapy, emphasizing helping clients move beyond insight and into meaningful, lasting changes. He also provides training and clinical supervision in EMDR therapy and trauma-focused care.
Many who seek his mental health therapy are high-functioning, responsible, and outwardly composed individuals. They come not because they can’t function, but because something unresolved continues to shape how they feel, relate, or carry stress—often in ways that haven’t shifted despite insight, effort, or prior therapy. His style is deeply relational and direct, with careful pacing and a steady, confident approach to the work—helping clients feel understood quickly while remaining oriented toward lasting change.
Dr. Tirabassi provides private-pay psychological services in person at the Tosa Psychological Services clinic and via telehealth in all PSYPACT states. Tosa Psychological Services is designed for those who value discretion, continuity, and specialized psychological expertise.
Advanced Training & Clinical Leadership
Dr. Tirabassi completed a trauma-focused residency at SSM Health, where he later served as a Clinical Supervisor and Training Committee Member.
