With over 10 years of experience as a therapist, I’ve had the privilege of supporting individuals, couples, and families through a variety of life challenges. I have a passion for helping clients navigate change, heal from past experiences, and build resilience. I’ve supported individuals, teens, children, and families.
My goal as a therapist is to create a safe, supportive, and nonjudgmental space where you can explore your experiences and begin to heal. I specialize in helping individuals, couples, and families navigate life transitions, relationship challenges, anxiety, depression and trauma.
Taking the first step can feel intimidating, but you don’t have to do it alone. I’d be honored to walk alongside you on your journey toward healing and growth. My availability is limited, and I currently offer virtual sessions only—providing flexible, accessible care with the same quality as in-person support.
