My name is Rosa, but everyone calls me Rosie. I am a bilingual English and Spanish-speaking Psychiatric Mental Health Nurse Practitioner. I’ve been a nurse since 2007, and working in mental health has always been my passion and a source of dedication. I earned my Master’s degree with honors from West Coast University in Anaheim, where I deepened my commitment to providing compassionate, evidence-based care. I’d be honored to walk alongside you on your journey to healing. You don’t have to face these challenges alone. Healing is possible, and you are not alone.

I offer a safe and compassionate space where your struggles are validated and your strengths are acknowledged. I believe in empowering you to reconnect with your inner resilience because you don’t have to face these challenges alone. Healing is possible, and you are not alone. 

I am dedicated to creating a compassionate and welcoming space, one where we can work together to achieve your personal goals for wellness. With over 7 years of experience in mental health nursing, I specialize in treating depression, anxiety, mood disorders, and trauma-related conditions. My primary focus is on medication management, alongside brief cognitive behavioral therapy (CBT) and supportive therapy all aimed at empowering you to make positive changes and feel supported every step of the way. Together, we’ll navigate the path toward healing, growth, and lasting well-being.

Me encantaría trabajar contigo, acompañarte y apoyarte en los momentos más difíciles. Mi objetivo es ofrecerte un espacio seguro y compasivo donde tus experiencias sean escuchadas y tus fortalezas reconocidas. Juntos podemos avanzar hacia tu bienestar emocional, con respeto, empatía y esperanza.
