Hi, I’m Hannah, a board-certified Psychiatric Mental Health Nurse Practitioner with a diverse background in critical care, trauma, and outpatient mental health. I’ve spent more than a decade working with individuals across the lifespan—from complex medical settings to telepsychiatry—helping people navigate mood disorders, anxiety, trauma-related symptoms, ADHD, and the stressors that come with major life transitions.
My clinical approach blends evidence-based medication management with supportive, collaborative care. I believe treatment works best when we tailor it to your unique goals, experiences, and strengths. Many of my clients are young parents, students, or adults balancing work, relationships, and emotional challenges, and I strive to create a space where you feel understood, empowered, and supported.
Diana Lankenau has a Master of Science in Nursing from Florida State University and Chamberlain University. She has a Bachelor's in nursing from University of Miami. BA in Psychology from Florida International University. She is Board Certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) and Family Nurse Practitioner (FNP-BC).
With over 30 years of experience, I help adults manage sleep, stress, anxiety, depression, and ADHD. People often describe me as kind, perceptive, with a good sense of humor. My approach combines active listening, mindfulness, CBT, and applied neuroscience. We'll work together to create a plan tailored to your needs to help you focus and move forward with confidence.
