I'm a board-certified psychiatric-mental health nurse practitioner with over 10+ of experience in the mental health field, and 3 years as a psychiatric mental health nurse practitioner. I founded Isimi Health & Wellness to provide thoughtful, evidence-based psychiatric care rooted in compassion, cultural humility, and a deep respect for the mind-body connection. My clinical background spans across PHP/IOP settings, Outpatient psychiatry, TMS, and telepsychiatry. I’ve worked with diverse populations experiencing anxiety, depression, trauma, mood disorders, and life transitions. Whether you're seeking support for mood instability, clarity around your medication options, or a space to reset and realign, I’m honored to walk alongside you on your wellness journey.

Hello.

• I’m excited about working together.

I'm a board-certified Psychiatric Mental Health Nurse Practitioner with experience assessing and treating a broad range of psychiatric conditions. I see patients from young adults through older adulthood. My practice is largely focused on adults dealing with stress, mood changes, sleep issues, and the cumulative weight of work, relationships, and responsibility, and questions of spirituality. I respect your time, your autonomy, and your intelligence.

I have a doctorate degree in nursing from Maryville University St Louis, Missouri. I have clinical experience in mental health services of over ten years. I excel in psychiatric evaluation and medication management,enhancing patient well-being through expert care and cultural competent practices.

My approach blends clinical rigor with genuine warmth. I ask a lot of questions, not to check boxes, but because I want to understand the full picture of your life, biology, and history before we decide on a path forward. I'm not interested in just managing symptoms; I want to understand the root of what's going on — whether that's biological, situational, relational, or some combination- so that treatment actually addresses the cause, not just the surface presentation. Clients often describe our sessions as feeling more like being truly listened to than being processed through an appointment. As an integrative provider, medication is one tool among several we might use, and I stay curious rather than settling for the first explanation.

Welcome! As a board-certified physician dual-trained in Psychiatry and Neurology (MD), I offer a comprehensive approach to brain health and emotional well-being by bridging the connection between the mind and the nervous system.
