Meet Marianne Guevarra, MSN, APRN, FNP-C, PMHNP-BC

Hello, I’m Marianne Guevarra, a board-certified Family and Psychiatric–Mental Health Nurse Practitioner.


My professional path began in family medicine, where I developed a keen appreciation for how mind and body are inseparable. Over time, I witnessed how emotional pain often lived quietly behind physical symptoms. This insight led me to advanced training in psychiatric care and to the study of psychoanalytic psychotherapy—a form of therapy that invites reflection and helps people uncover deeper sources of meaning and resilience.

  • Education & Credentials

    • Master of Science in Nursing

    • Board certifications in Family Practice (FNP-C) and Psychiatric–Mental Health Nursing (PMHNP-BC)

    • Ongoing training in psychoanalytic psychotherapy

My practice is informed by the wisdom of thinkers like Thich Nhat Hanh, whose words guide me:

“The seed of suffering in you may be strong, but don’t wait until you have no more suffering before allowing yourself to be happy.”
