Whether you have questions about medication use in pregnancy, seek diagnostic clarity, or are ready to take the first step in changing your life, I’m here to help you discover your unique path forward. I offer integrative mental health care grounded in trauma-informed, evidence-based practices and collaborative decision-making. I believe in a personalized approach, there is no one-size-fits-all in mental health care, and I’m committed to working alongside you to find what supports your well-being. I work with individuals of all ages and demographics. In network, no wait-list, and services available in Spanish!

I love working with peripartum/postpartum individuals, adolescents, and anyone who is motivated to make meaningful changes in their life. My practice considers the whole person - incorporating lifestyle guidance, supportive alternative therapies, and current psychiatric research to develop a treatment plan that is approachable and tailored to you.

Above all, I value genuine connection and a collaborative therapeutic relationship. I listen closely to your goals, concerns, and questions, and I’m here to support you every step of the way. If you're ready to take the next step, I’d be honored to walk with you on your path to wellness.

I work with clients who may have questions about their current diagnosis or treatment plan as well as see new patients eager to improve their lives. The first session is usually 60 minutes and together we will explore your concerns, discuss a treatment plan, and agree on next steps. Most of my clients visit every 2 weeks until they feel stable and every 1-3 months thereafter.

I am passionate about EMDR therapy in my practice. EMDR therapy is about so much more than reprocessing trauma, it is about re-writing the narrative of your life to one that you get to tell, one where you matter, are loved, and are seen for all the wonderful things you bring to the table. Come start a new journey to knowing and loving yourself today.
