I am a doctorate- prepared, board-certified PMHNP who understands how difficult it can be to share your personal information. I offer a nonjudgmental space where you can feel safe, valued, and heard. Treatment provided is individualized based on your symptoms. I believe in a more holistic approach to care and am passionate about seeing you feel better. I partner with other psychiatric providers to ensure the best outcome. Choose today to begin your journey to wellness.
I know how heavy life can feel when you’re carrying pain, uncertainty, or self-doubt. But I believe, as a wise old wizard once said, “Happiness can be found even in the darkest of places, if one only remembers to turn on the light.” My role is to help you find that light again. I work with Gen Z and Millennial adults facing anxiety, depression, trauma, bipolar disorder, ADHD, and more. Through integrative, culturally responsive care, I combine evidence-based psychiatry with holistic strategies to help you feel heard, supported, and empowered to create a life that aligns with your true self.
