I am a Licensed Professional Counselor who works with adults, adolescents, and couples navigating life’s challenges, including anxiety, depression, trauma, and relationship concerns. I earned my Master’s degree in Professional Counseling from Grand Canyon University and have additional training in EMDR. I offer services in both English and Spanish, creating a space where clients can express themselves comfortably and authentically. My goal is to provide a supportive, nonjudgmental environment where you feel heard and understood.
I am trained in EMDR, CBT, DBT, EFT, Gottmans and much more as well as being a client centered, trauma informed LCSW who makes my clients a priority. I treat many issues but specialize in trauma, grief, comorbidities, end of life, identity challenges, anxiety, depression and helping you thrive regardless!

I’m a psychiatric nurse practitioner dedicated to providing thoughtful, patient-centered mental health care.

If you’re feeling overwhelmed, stuck in your thoughts, or carrying stress that just won’t seem to let up, you’re not alone. You might look like you’re holding everything together on the outside, but inside it feels heavy, exhausting, or unclear how to move forward. Therapy can be a place where you finally feel heard — without judgment.
I work with adults navigating anxiety, depression, trauma, relationship challenges, and life transitions. Many of my clients come in unsure of why they feel the way they do, or frustrated that things haven’t changed despite their efforts. Together, we’ll begin to make sense of what’s going on beneath the surface so you can feel more grounded, clear, and in control of your life.
