Donna’s work as a crisis advocate for survivors of sexual assault and domestic abuse inspired her to pursue counseling full time.

Donna values open communication and believes in creating a warm, supportive environment where patients feel respected and understood. With over fifteen years of experience helping individuals heal from trauma, she views the therapeutic process as an opportunity for patients to reclaim their voices and move from “victim to survivor” on their own terms. Patients can expect empathy, collaboration, and a strong sense of safety in her care.

Donna begins each therapeutic relationship by establishing trust and safety, encouraging honest dialogue around personal and family challenges. She integrates education, reflection, and resource sharing on topics like communication and conflict resolution.
