Our Clinical Philosophy

What Sets SMHWI's Board-Certified Psychiatrists Apart

Our board-certified psychiatrists in Arizona and Texas are not administrators removed from day-to-day care. They are active, practicing physicians who shape both clinical policy and individual patient outcomes.

Interventional Psychiatry Expertise

Our directors lead a practice offering the full spectrum of FDA-cleared interventional treatments: TMS, Spravato (esketamine), and ketamine — for patients who have not responded to standard care. All four locations. Most insurance accepted.

Active Clinical Practice

Each medical director maintains an active patient practice alongside their leadership role. Their oversight of clinical programs is informed by real, current patient care — not detached from it.

Subspecialty Depth at Every Location

Between them, SMHWI's medical directors hold certifications and fellowship training in Forensic Psychiatry, Addiction Psychiatry, Consultation-Liaison, Geriatric Psychiatry, Obesity Medicine, and Emergency Psychiatry.

Academic & Clinical Credentials

Training, Certifications & Affiliations

SMHWI's board-certified psychiatrists bring academic, research, and subspecialty credentials that are rarely found together in a single integrated psychiatric practice in Arizona or Texas.

University of Arizona — Clinical Faculty

Drs. Segal and Abdallah both serve as Clinical Assistant Professors of Psychiatry at the University of Arizona, maintaining active teaching and academic roles alongside their clinical practice.

ABPN Board Certification — All Four Directors

Every SMHWI medical director holds American Board of Psychiatry and Neurology (ABPN) certification. Dr. Abdallah and Dr. Bonner each hold triple board certifications across subspecialties.

NIH-Funded Research & Peer-Reviewed Publications

Dr. Bonner is an NIH grant recipient and has published in peer-reviewed journals including Neurology and Academic Psychiatry, bringing a research-informed lens to SMHWI's clinical programs.

Forensic & Fellowship-Level Training
