"We were so saddened to just now find out that Kathy had passed. The last time we saw her and Alex was mid January having breakfast at Eddie's Cafe. We knew she didn't look very well then, but we didn't ask questions...felt like she wanted privacy. Kathy will be dearly missed by all, it was a pleasure knowing you and hanging out on Friday nights at Chili's in Los Banos. Rest in Peace my friend!!!"

"I am so heartbroken by the loss of Kathy, my dear friend and colleague. Our paths crossed long before we ever work together, and over nearly 30+ years we shared so many moments, both in and out of work. Her passing came as such a shock. She was truly an amazing kind woman, and she will be deeply missed. My heartfelt condolences go out to her family during this incredibly difficult time. Alex, I am holding you and your family in my thoughts and prayers. Rest in peace, Kathy.
Mona Cordova & family "
