Leslie Dutcher Treviño studied Radiology at Tarrant County College and worked as the Patient care Coordinator for Solis Women’s Health, and a clinical operations and compliance director of Texas Health Resources. During her career she worked as a coordinator with the The Susan G. Komen Foundation organizing the yearly Race For The Cure, and as an American Cancer Society ambassador, & Registrar. This experience in compliance & nonprofit charitable work coupled with her 14-years experience conducting archival research, enabled her to establish the Webber Family Preservation Project.

As President of the Webber Family Preservation Project she has secured historical markers through the Texas Historical Commission, and given presentations with public & academic organizations on historic research & preservation.

Most recently she led her organization to co-curate an exhibit with the Dolph Briscoe Center, at the University of Texas in Austin, centered on the Freedom Papers of Silvia Hector Webber.

This exhibit garnered national interest from the Smithsonian’s National African American Museum in Washington DC (who may be supporting a traveling exhibit in the near future) and the Today Show (who featured their story as its Juneteenth episode this year).

Her husband Omar J. Trevińo and their son Dean are both direct descendants of John Webber and Silvia Hector-Webber. She lives in North Fort Worth/Keller with her family and their chihuahua Bella.
