Julia Philips, Community Programs Coordinator

Shortly after graduating from Cal State East Bay with a Bachelor degree in Hospitality and Tourism Julia began working at a large urban hotel where she now holds a supervisor position. She is also currently attending a graduate program to obtain her Masters in School Counseling.
Following ten years as a Bearskin counselor, group coordinator and year-round programs/events support person she is excited about her new role at DYF as Community Programs Coordinator. Julia began attending camp at the age of three, first as a family camper, then as a kids camper, followed by participation in the teen program, and then as a LIT. Camp was the place for so many diabetic firsts, including finger pokes, shots, and finding new set locations. All of this diabetes growth and knowledge was only possible due to the encouragement and support of DYF staff. So, coming on board as part of the DYF year-round team is a dream come true for Julia.

In Julia’s free time, she enjoys hanging out with family, friends, and her new puppy, Moira Rose.
