Our licensed psychotherapists work together with our medical team to provide comprehensive care.

We conduct thorough evaluations to uncover the various factors contributing to your suffering. This includes assessing biological predispositions, family dynamics, problematic behaviors, psychological traits, life circumstances, and social stressors. By understanding these elements, we can create personalized treatment plans that align with your unique needs and goals.

Dr. Syed Mustafa Hassan, MD
Dr. Hassan believes good psychiatric care begins with being seen as a whole person, not as a diagnosis or a prescription. His clinical work is rooted in the intersection of psychiatric neuroscience, integrative medicine, and metabolic health, with a focus on understanding what may be driving symptoms beneath the surface.
Dr. Hassan completed medical school at The University of Queensland and his psychiatry residency at the University of Arizona, where he pursued hands-on training in integrative medicine through the Andrew Weil Center for Integrative Medicine and presented a whole-
person framework for insomnia care — work that shaped his interest in sleep, burnout, and resilience. As an adult psychiatrist, he works with people experiencing depression, anxiety, OCD, PTSD, ADHD, insomnia, burnout, and treatment-resistant depression, with a particular interest in those whose symptoms have been difficult to treat or who feel they have already tried everything.
No two people arrive with the same story, so no two treatment plans should look alike. Dr. Hassan takes the time to understand each patient’s story and builds care around it, drawing on established, evidence-based treatments alongside newer integrative approaches. Depending on what fits, that may include medication, interventional options such as Trans-cranial Magnetic Stimulation (TMS) and intranasal ketamine therapy — FDA-approved, Spravato — as well as nutrition, movement, and sleep optimization. For Dr. Hassan, healing is more than symptom relief; it is feeling reconnected to oneself and one's community. When symptoms have taken someone away from their life, he sees thoughtful and effective treatment as a way to help them get back to the people, responsibilities, and parts of themselves that matter most.
Outside of work, Dr. Hassan enjoys Houston's incredible food, sports, and arts.
