About Me
I believe in a collaborative approach to care, providing medical expertise and asking thoughtful questions while supporting patients in making decisions that align with their goals.
I love helping people regain their sense of themselves and reconnect with the people and activities they love. As a natural problem-solver, I like the complexity of psychiatry, where biology, life experiences and relationships all contribute to the bigger picture.
After a decade as an investment analyst, I was drawn to psychiatry after seeing firsthand how mental health connects medicine and meaning during my years working in inpatient psychiatry and intensive care. I knew I had found my place in a field that allowed me to focus on the whole person rather than the diagnosis and help patients work toward their life goals.
