Briana is a Board-Certified Psychiatric Mental Health Nurse Practitioner, deeply committed to providing high-quality, compassionate mental health care to the community she calls home. She is dedicated to creating a safe, collaborative, and nonjudgmental environment where patients feel heard, understood, and empowered to take an active role in their mental health journey.
She brings over 11 years of healthcare experience, beginning her career with eight years in pharmacy before transitioning into nursing. This early foundation provided her with a strong understanding of psychopharmacology, medication mechanisms, and the importance of precision in medication management. She earned her Bachelor of Science in Nursing from the Arizona College of Nursing and completed her Master of Science in Nursing Psychiatric Mental Health Nurse Practitioner at Herzing University in 2025. Her clinical background includes experience in both the Neuro Intensive Care Unit and the Emergency Department, where she cared for medically complex and critically ill patients in high-acuity, fast-paced environments that required rapid clinical judgment, emotional resilience, and trauma-informed care.
She primarily focuses on comprehensive psychiatric evaluations and medication management, working with high-acuity outpatient populations across a wide range of psychiatric conditions. Her approach emphasizes careful diagnostic assessment, thoughtful medication selection, and ongoing monitoring to support stability, symptom reduction, and improved quality of life. With a strong foundation in both pharmacology and direct patient care, she integrates clinical evidence with individualized treatment planning, ensuring that each plan is tailored to the patient’s unique history, goals, and lived experience. She values shared decision-making and strives to ensure patients are informed, supported, and actively involved in every step of their care.
Briana’s clinical style is rooted in empathy, respect, and clear communication. She understands that mental health is deeply connected to life experiences, relationships, and environmental stressors, and she takes a holistic view of each individual’s needs. She is especially passionate about supporting couples navigating relationship challenges and co-parenting, children of divorced parents, teens and adults managing complex emotional and behavioral stressors, and individuals adapting to significant life changes such as chronic medical conditions, trauma, grief, or loss.
She incorporates developmentally appropriate and creative interventions when helpful, including elements of art- and play-informed approaches to help patients express themselves in ways that feel safe and natural—particularly for children and adolescents. She also integrates structured journaling and reflective practices to help patients build insight, identify emotional patterns, and strengthen self-awareness over time. Her goal is to meet patients where they are and help them build practical, sustainable skills that support long-term emotional wellness.

What People Are Saying
“I am a first time therapy goer and at first I was naturally nervous/scared for it. Briana has been great and so welcoming. She is very interactive, helps me when I’m stuck, and very patient as I think through my thoughts or what I want to talk about. I’m definitely happy with my choice of seeking professional help as I work through some of my challenges I struggle with regarding my mental well being. I also enjoy the goal setting and journaling that I will do outside of our actual sessions. I’m eager to continue my journey and find success through each session.”
