I’m Fatoumata Diallo, PMHNP‐BC, a psychiatric mental health nurse practitioner providing care to individuals ages 10 through older adulthood across Texas. My work is rooted in empathy, cultural humility, and a deep respect for each person’s lived experience.
I specialize in anxiety, depression, PTSD, ADHD, OCD, and mood disorders, with a particular passion for supporting clients through life transitions, trauma recovery, and emotional overwhelm. I believe mental health care should feel collaborative, transparent, and empowering.
My approach blends medication management, supportive therapy, and psychoeducation, always tailored to your unique goals and strengths. To enhance continuity and access, my practice also offers membership services that provide ongoing support between visits.
My mission is to help you feel more grounded, more hopeful, and more in control of your mental health journey.
I am a doctoral-prepared nurse (DNP) and a dual-certified nurse practitioner (FNP-C/PMHNP-BC) with more than twenty years of nursing experience. I am great at combining my clinical skills with a holistic approach to patient care, with a goal of helping you feel understood and empowered. I am committed to improving patient outcomes through clear communication and care planning and implementing evidence-based treatment plans.
Hi! I am a dual-certified Family Nurse Practitioner (FNP) and Psychiatric Mental Health Nurse Practitioner (PMHNP). I graduated with FNP from the University of Tennessee Health Science Center in 2016. I practiced in a rural health family practice clinic for 5 years before returning to school to get my PMHNP to provide better care for my clients. I help children and adults ages 5 and up overcome life's challenges and achieve mental well-being.
