Everyone who knows me knows I love Portola and redwood forests. I credit my father for passing on his love of nature and redwood trees.

My degree from San Jose State is in Nutrition Science and I interned at Sutter Hospitals in Sacramento with post grad classes at UC Davis. I’m now a retired Registered Dietitian who had specialized in diabetes in pregnancy. I have camped and/or visited many State Parks in California and believe strongly in nature as a stress reliever. Now that I’m retired, it is my turn to support the parks that I love by helping visitors enjoy their visit and find the same sense of peace and enjoyment in connecting with nature.
