Deborah Jenkins LBSW, LCCA

Child Care Administrator
Director of HR

Deborah has worked with children and teens in crisis since 1977.  She became a Licensed Child Care Administrator in 1989 and oversaw an emergency shelter in the Houston Area, providing care for many teens that were displaced, runaways and those struggling with substance use/abuse.   Deborah joined the Shoreline team in 1992 as the Behavioral Program Director. The goal at that time was to integrate a program of sobriety/counseling with teaching clients to replace negative behaviors with positive behaviors in hope that they would be more successful in having a sober lifestyle after discharge. In 1993 she obtained the LBSW degree.  In 1998 she developed the Human Resource department, where she has provided her steady leadership for the past 24 years.
