Merly Costa, NP, is a Board-Certified Psychiatric-Mental Health Nurse Practitioner who brings a holistic, compassionate, and evidence-based approach to her practice. Growing up on a picturesque island in southern Brazil, Merly was surrounded by hills and beaches—experiences that instilled in her a deep appreciation for nature, freedom, and resilience. Her spiritual upbringing further shaped her values, sparking a lifelong desire to help others and make a meaningful impact.

Merly earned her Master of Science in Nursing (MSN) from Chamberlain University, complementing her diverse educational background, which also includes a Bachelor of Science in Film Studies from Sacramento State University and a Bachelor of Science in Nursing from the Federal University of Santa Catarina in Brazil. She is currently pursuing her Doctor of Nursing Practice (DNP), a reflection of her ongoing commitment to clinical excellence and lifelong learning. These academic and life experiences give her a unique perspective that blends creativity, empathy, and purpose-driven care.

Her journey into psychiatry was driven by a deep curiosity about human behavior and a belief in the healing power of compassionate, personalized care. Merly is dedicated to understanding each client’s individual needs and delivering empathetic, evidence-based treatment that promotes resilience and meaningful progress. Her approach is holistic, emphasizing the mind-body connection and the integration of medication management with supportive lifestyle practices.

Merly is committed to creating a safe, collaborative space where clients feel seen, heard, and empowered. She believes that effective mental health care goes beyond symptom relief—it involves nurturing the whole person and guiding them toward a life of purpose, clarity, and emotional balance.

When she’s not working, Merly finds renewal in nature—hiking, spending time near the water, or enjoying peaceful outdoor moments with her family, friends, and her rescued dogs. She also expresses her creativity through reading, writing, and music, which help recharge her spirit and bring fresh insight to her work. Compassionate, resourceful, and purpose-driven, Merly is honored to walk alongside her clients on their journeys to healing and growth.
