Hi there, I'm Sheila! I am a board-certified psychiatric mental health nurse practitioner. I provide personalized, culturally sensitive care through a holistic and collaborative approach, integrating psychotherapy and medication management to support overall well-being. My focus areas include treating anxiety, depression, OCD, mood disorders, PTSD, and ADHD for individuals across the lifespan. DNP, PMHNP-BC. My approach to mental healthcare is holistic, patient-centered, and culturally responsive, with an emphasis on the interconnectedness of mind, body, and spirit.
I approach goal setting with clients in a collaborative, personalized, and strengths-based manner. I begin by exploring each individual’s values, priorities, and personal definition of wellness. Together, we identify clear, realistic, and meaningful goals that align with their life circumstances and desired outcomes.
My communication style is warm, empathetic, and collaborative, creating a therapeutic environment that feels safe, supportive, and non-judgmental. In sessions, I prioritize active listening and genuine connection, creating space for clients to feel seen, heard, and respected. Working with me feels like being in a space where healing is possible.
