I am a Licensed Professional Counselor and Nationally Certified Counselor. If someone in your life makes you feel guilty, confused, unloved, or stressed, I'm here to support you.

I work with courageous people healing from the trauma of toxic relationships and I assist them in developing assertive communication skills & unlocking the power behind setting healthy boundaries. Together, we can reclaim your self-worth and build a life filled with empowerment and resilience.
