Hello! I'm Michael Nguyen, a board-certified Psychiatric Mental Health Nurse Practitioner dedicated to helping individuals navigate their mental health journey with compassion and evidence-based care.
I earned my Master of Science in Nursing from the University of California, San Francisco (UCSF), specializing in psychiatric mental health. My foundation in psychology from UC San Diego, combined with my nursing training, allows me to approach mental health from both a scientific and deeply humanistic perspective.
Throughout my career, I've had the privilege of working with diverse populations across the San Francisco Bay Area. I specialize in treating individuals with treatment-resistant depression, anxiety, PTSD, and ADHD. I have extensive experience providing care to those with complex mental illness and substance use disorders, having worked in community mental health settings where I supported some of our most vulnerable populations.
My expertise includes traditional medication management and psychotherapy, as well as innovative treatments like transcranial magnetic stimulation (TMS) and esketamine (Spravato) for treatment-resistant depression. I'm committed to cultural humility and destigmatizing mental health challenges, ensuring every client feels respected and understood.
Before becoming a nurse practitioner, I worked as a medical scribe and performance improvement coordinator, which taught me the importance of clear communication and patient-centered care. I believe in meeting people where they are and collaborating with them to find the path forward that works best for their unique circumstances. I've also worked extensively with LGBTQ+ youth and individuals from marginalized communities, and I understand the unique challenges that systemic barriers can create in accessing quality mental health care. I stay current through continuing education to provide the highest quality care.
I'm Shara Ally, DNP, PMHNP-BC I provide evidence-based medication management for adults (18+) via telehealth. As an author and TEDx speaker, I translate complex research into clear, practical care plans that help my patients feel informed and supported.
I specialize in mood and anxiety disorders, trauma-related conditions (PTSD), adult ADHD, OCD, bipolar spectrum disorders, and women's mental health across the reproductive lifespan—including perinatal and postpartum mood disorders, PMDD, and menopausal transitions. My practice is medication-focused and highly collaborative, with education, skills coaching, and supportive check-ins integrated into every visit. I coordinate closely with therapists, primary care providers, OB-GYNs, and other clinicians to ensure cohesive, connected treatment.
When you work with me, you can expect a comprehensive evaluation reviewing your history, symptoms, prior treatments, and goals. I practice thoughtful prescribing with transparent discussion of options, benefits, and side effects so that every decision is truly shared. I use measurement-based care—structured symptom tracking—to guide adjustments and reduce trial-and-error. My whole-person approach integrates sleep, nutrition, movement, and stress management when relevant, with streamlined access through secure telehealth and clear after-visit summaries.
My style is warm, direct, and person-centered, grounded in shared decision-making. My care is trauma-informed, culturally responsive, and rooted in current clinical evidence. Beyond my clinical practice, I serve as a nurse educator and academic mentor, shaping future psychiatric clinicians through evidence-based teaching. An international fellowship in India further enriched my global perspective through research and teaching in hospital and university settings.
