My clinical style is warm, structured, and collaborative. I emphasize clear communication and shared decision-making with my patients. I strive to create a safe and non-judgmental environment where people feel heard and respected.
I have an AGACNP background, which supports my ability to assess medical comorbidity and understand complex medical/psychiatric overlap. I am also DOT-certified, which reflects my knowledge of safety-sensitive considerations and careful medication risk assessment.
