Hello there! I’m Diana, a board-certified Psychiatric Mental Health Nurse Practitioner, and I’m here to support you on your mental health journey! With experience in both inpatient and outpatient settings, I work with diverse populations and have a strong clinical background in mood disorders, addiction and withdrawal, and psychiatric emergencies.
I especially enjoy working with clients who feel stuck, overwhelmed, or unsure where to start, and I help them build practical, realistic strategies that feel manageable and actually work.
I provide personalized mental health care for adults and adolescents struggling with anxiety, depression, ADHD, PTSD, OCD, bipolar disorder, and related concerns. My focus is helping you feel better, think more clearly, and regain control of your daily life.
I offer comprehensive evaluations and medication management through secure telehealth across Texas, with in-person availability in the Dallas–Fort Worth area. Treatment is tailored to your unique needs, with careful attention to effectiveness, side effects, and long-term stability.
Hi! I'm a dual-certified Psychiatric Mental Health NP from Johns Hopkins University (2020) & Family NP from UT Austin (2017), a veteran flight nurse, as well as a certified Yoga instructor & Reiki practitioner. I practice Integrative Psychiatry—merging best practices from Eastern & Western Healthcare for a truly holistic approach. I help adults grappling with mental health challenges to reclaim their life, fostering overall health & mental well-being.
I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) providing compassionate, holistic mental health care for individuals across the lifespan. I work with clients experiencing anxiety, depression, ADHD, bipolar disorder, PTSD, insomnia, schizophrenia, and substance use challenges, helping them regain balance and confidence in their lives.
My approach to care is warm, empowering, and collaborative. I believe every person deserves to feel heard, understood, and supported while navigating their mental health journey. I work closely with each client to develop a personalized treatment plan that supports emotional well-being, symptom management, and long-term stability.
With experience in both inpatient and outpatient psychiatric settings, I have supported individuals facing complex mental health challenges and life stressors. I provide comprehensive psychiatric evaluations, medication management, and supportive therapy, while incorporating lifestyle and coping strategies that promote lasting wellness.
I am passionate about helping people develop the tools and understanding they need to take control of their mental health. My goal is to create a safe, judgment-free environment where clients feel comfortable sharing their experiences and working toward meaningful change.
You’re the one who usually has everything under control, but lately, the "strong" version of you feels like a mask that’s getting too heavy to wear. Whether you’re a mother wondering why you feel detached from the life you worked so hard to build, or a parent exhausted by the cycle of ADHD-related challenges—you don’t have to carry this alone.
I provide a warm, judgment-free space where you can stop surviving and start thriving. My approach is patient-centered, trauma-informed, and evidence-based, tailored to move you toward a life where you feel present, connected, and capable.
