Psychiatric symptoms deserve the same seriousness, expertise, and unwavering support as any medical condition. I know seeking help takes courage. I know healing rarely follows a straight line.
I’m a board-certified Psychiatric-Mental Health Nurse Practitioner (PMHNP) with a background in nursing across a range of mental health settings, including outpatient care and higher-acuity environments. My training has focused on assessing, diagnosing, and treating conditions such as depression, anxiety, bipolar disorder, trauma-related disorders, and substance use, using both medication management and psychotherapy. I completed advanced graduate education in psychiatric-mental health nursing, which prepared me to provide holistic, evidence-based care across the lifespan and to collaborate closely with other members of the treatment team.
I am a Psychiatric Mental Health Nurse Practitioner who works with adults experiencing anxiety, depression, trauma-related symptoms, mood disorders, OCD, and substance use concerns. My background includes structured treatment settings supporting recovery, stabilization, and long-term mental health management.
I provide warm, practical, and judgment-free care where clients feel heard and supported. Many people come to treatment feeling overwhelmed or unsure where to begin, and my goal is to simplify the process and provide clear direction forward.
I focus on thoughtful medication management and practical strategies that support lasting stability and meaningful progress.
It’s okay to need support. Life can become overwhelming when anxiety, mood changes, trauma, depression, or panic begin affecting your ability to feel like yourself. You may notice your mind won’t slow down, your sleep is off, or it’s harder to focus and keep up with daily responsibilities. When stress builds or world events add to the weight you’re carrying, it can start to feel like too much to manage alone. Many people reach a point where coping strategies no longer feel like enough, and that’s often when support can make a real difference.
I believe care should feel personal, not rushed or one-size-fits-all. I take time to understand your story, not just your symptoms, and create a space where you feel comfortable being open without fear of judgment. I’ll be honest and supportive, helping you make sense of what you’re experiencing while offering guidance that feels practical and manageable.
My goal is to help you feel more balanced, clear, and confident in navigating your day-to-day life.

As a Psychiatric Nurse Practitioner, I help clients find balance and feel better using an approach that is always compassionate and non-judgmental.

My approach to mental health care centers entirely around you. True healing happens when trust, safety, and collaboration come together.

As a board-certified adult psychiatrist, I bring unique depth to my clinical practice. I earned both my MD and PhD from the Albert Einstein College of Medicine, grounding my approach to medication management in advanced scientific research and evidence-based medicine.
My leadership and clinical training within the University of Texas Health System—including roles as Chief Resident, Assistant Medical Director, and Assistant Professor—deeply shaped my view of mental health. Having cared for individuals across institutions like MD Anderson, Memorial Hermann, the Dunn Behavioral Sciences Center, and Maui Memorial Medical Center, I possess the outpatient and inpatient expertise required to manage complex clinical cases with complete confidence.
I provide convenient, high-quality telepsychiatry and virtual care for adults (ages 18 and older) actively located in Texas, California, Hawaii, and Alaska.
