“Through the use of collective imagery in glass, this work reflects my interest in the role of women artists throughout history. Up until very recently, these artists have been ignored or subjugated to the sidelines by the historians. I have been following my own interests and curiosities concerning how these women have navigated their careers and artistic practices. I represent these ideas in glass through the details that speak to me, particularly the ephemera of material culture, furniture and clothing that encapsulate their era and class. I also rely on posture and facial expression to reveal the nature of the subject as I intuit it. It has been through my own investigation into the stories of other women artists that I have brought greater recognition to the artists. Other subjects that I choose are stylized characters and self-portraits of women that show a glimpse into an imagined experience and relationships through the lens of my own poetic eye.”

Trenchard's process is to sculpt and paint objects in glass that tell illusory narratives. The sculpted pieces are encased in sand cast glass forms. The cast pieces are assembled in different sections, often stacked or nestled together and, on occasion, can be reconfigured. A successful work speaks to the viewer as if in an intimate conversation. The focus of her work continues to be the issues concerning women in the arts through a study of narratives, relationships and material culture.

Her work also involves using art as a way to communicate local activism, including her project About Sturgeon Bay.
