I’m dedicated to providing compassionate, evidence-based mental health care for individuals of all backgrounds. My goal is to create a safe space where you feel supported, understood, and empowered to take control of your mental well-being. I value collaboration, transparency, and genuine connection in the healing process.
I am a dual board-certified psychiatric and geriatric nurse practitioner with over 25 years of healthcare experience, providing compassionate, evidence-based mental health care to young adults, adults, and older adults. I specialize in treating depression, anxiety, insomnia, bipolar disorder, schizophrenia spectrum disorders, and behavioral or psychological symptoms associated with dementia and complex medical conditions.
My experience spans hospital care, rehabilitation, hospice, and long-term care settings, giving me a deep understanding of the connection between physical and mental health. I am especially comfortable supporting individuals with multiple medical concerns or those navigating life transitions related to aging, illness, or stress.
