Miriam Fernandes, MSN, PMHNP-BC
I am a board-certified Psychiatric Mental Health Nurse Practitioner providing compassionate, evidence-based care to adults. I specialize in treating anxiety, depression, mood disorders, trauma-related conditions, and burnout. My professional background includes experience in both high-acuity and outpatient psychiatric settings, where I have worked with individuals facing complex emotional and behavioral health challenges.
I strive to create a safe, respectful space where clients feel heard and empowered. My goal is to partner with you in developing a treatment plan that supports long-term wellness and meaningful change.
Choosing a psychiatric provider is a personal decision, and I approach that with care. As a psychiatric nurse practitioner specializing in adult mental health, I focus on understanding you as a whole person and creating a treatment plan that fits your life.
I have worked with diverse populations and often see how anxiety, trauma, stress, and executive dysfunction can interfere with work, relationships, and overall well being. I treat adults with depression, anxiety, ADHD, and substance use concerns, with experience in both inpatient and outpatient settings, including complex cases. I especially enjoy working with college students, professionals, and business leaders who are balancing demanding schedules and high expectations. I also collaborate with caregivers and other professionals to ensure well rounded care.
