Linda has been involved in the station for over 28 years, assisting in the backroom office and helping with community projects.  In December of 2013, Linda led our “Christmas Truck” Giveaway, where we gave away a Ford F-250 to a local family in-need. Linda was able to gather a number of donations from local businesses to fill the bed of the truck with toys and gifts for the family!

Her favorite memory of the station was in 1996, when she and Doug were able to watch the station go through a complete remodel. She can recall her son Josh, who was two at the time, watching all of the cranes and excavators work on the station with amazement.

Doug and Linda’s son Josh currently attends school at California State University, Monterey Bay where he is obtaining a degree in business. Their daughter Karley attends the University of Colorado Pueblo where she is studying Psychology. Karley is attending the university on both an academic and Soccer scholarship. In their spare time, their family enjoys camping, traveling and attending church at Water Of Life in Fontana, California.
