Why Muna?

Physician-led psychiatric care for women, children, teens, and adults — thoughtfully supporting mental health across life transitions in Katy and across Texas.

Physician-led psychiatric care across the lifespan

Care is provided by a Yale trained, double board-certified psychiatrist with advanced medical training, supporting brain health from pregnancy and postpartum through childhood, adolescence, and adulthood.

Never-Rushed, Thoughtful Appointments

We prioritize thorough evaluations, careful diagnosis, and individualized treatment planning. Appointments are intentionally paced so concerns related to ADHD, anxiety, depression, mood changes, and emotional regulation are addressed thoughtfully — not hurriedly.

Expertise in Complex & Overlapping Concerns

We support patients when symptoms overlap, diagnoses evolve, or progress has stalled — including ADHD, anxiety, depression, school difficulties, emotional dysregulation, and behavioral concerns. Care is grounded in real-life functioning, family dynamics, and school or work environments.

‍In-person and virtual — your choice

Telehealth visits are available statewide across Texas. In-person appointments are available in Houston and Katy.
