With over 24 years of experience, I bring a deep commitment to helping individuals, children, couples, and families understand, heal, and grow. You’ll be working with someone who emphasizes building on your existing strengths—believing the capacity for healthy change is already within you—and provides a safe, supportive environment tailored to your needs. From talk, art, and play therapy modalities to working with complex issues like trauma, anxiety, depression, ADHD, family conflict, and domestic abuse, my goal is to guide you toward greater clarity, healthier relationships, and a more satisfying life.
You're taking the first difficult step towards change by vetting therapists, and I'd be honored to join you on each of the subsequent steps. I've been a clinical therapist for 12 years and employ a variety of tools to help you meet your goals. I'm especially drawn to and skilled in working with folk in transition, whether this relates to your age (preteen, teen or adult), relationship status, identity exploration or shifting life circumstances.
I build trust quickly by listening deeply, validating their emotions, and walking alongside them through difficult seasons, ensuring they never feel alone in their journey.
I see myself as a companion on your journey, not just a clinician. I am dedicated to walking alongside you during their most vulnerable and challenging moments. My approach is gentle, nurturing, yet challenging and steadfast, offering hope and encouragement as you find your way towards healing.
I’m a bilingual therapist working with adults navigating anxiety, trauma, grief, and major life transitions. Many of the people I support feel overwhelmed by overthinking, internal pressure, difficulty managing stress, and the uncertainty of what comes next.
In our work together, I focus on helping you make sense of what’s happening internally and develop practical ways to respond to stress and emotions. I integrate cognitive, somatic, and neuroscience-informed approaches to support both emotional and nervous system regulation.
I believe therapy should feel human. It can be structured but still fit your individual needs. I offer a space where you can show up as you are, while also doing meaningful work that leads to real shifts in how you experience and respond to life.
I enjoy working with adults (ages eighteen and up). My specialty areas are depression, anxiety, grief and loss, and adjustment concerns.
