Did you know 1 in 6 people are food insecure in SLO County? Let’s change those numbers! Get on down to a participating location today. We met some smiling, very generous faces at the Vons in the Marigold shopping center.

Wallace Group’s fun committee took this party on the road – setting their sights on the Los Angeles Petersen Automotive Museum, the largest exhibition of science fiction and fantasy vehicles in the world.  Back to the Future’s Delorean, Luke Skywalker’s Landspeeder, and the original Jurassic Park Ford Explorer were among the many highlights.  Too bad they don’t allow test drives.

Wallace Group Kylie CastleHello! My name is Kylie and I have had the pleasure of working at Wallace Group for close to two years now. After graduating from UC Santa Barbara I wanted to move closer to my family in Cambria, somehow got lucky and wound up in the middle. I am the oldest of three, two girls, one boy. We moved from Fresno when I was in middle school – in retrospect a big turning point in my life. As resistant as I was in the beginning (teenage rage and all) I quickly gained admiration for the pines by the sea. Being from such a small town I was able to get involved in everything, learning the importance of community and education.Wallace Group Kylie Castle I studied Communication at UCSB, which is much different from most university programs. The program is theory-based, centering on human communication research, from relational/familial settings, to media, and even law. Essentially, I wasn’t practicing speeches or developing marketing plans. My major instilled a great love of writing, and what comes in most handy at Wallace Group – editing! Describe what you do at WG As a marketing coordinator I handle all proposals, large and small. I keep track of our clients and contracts, as well as subconsultants. I also write posts for all of our social media pages and website. What are some of your favorite activities with WG? Book club - We’ve been reading some thrilling mysteries. What are you involved in outside WG? I am involved in an organization called FeelGood, a student-run enterprise dedicated to the eradication of extreme hunger and poverty. There are 25 chapters across the US on college campuses, where students run their own fundraising campaigns, mostly through making and selling grilled cheese! I was co-president of one of these chapters at UCSB, where we would cater, set up delis with our panini presses, and sometimes even deliver grilled cheese. All proceeds from these events are given directly to four non-profit organizations, each addressing several of the Sustainable Development Goals set by the UN. I’ve been lucky enough to work with them these past 5 years, and even had the opportunity to witness hands on the ground in an expedition to Peru. I currently serve as an alumni volunteer, assisting the chapter at UC Berkeley. Favorite pastime Napping! Or reading. . . or reading until it turns into a nap Favorite movie Mamma Mia (and now Mamma Mia 2) – I will sing the whole movie Favorite food Sushi or tamales Describe your dream vacation. Laying on a beach under the sun in Greece, where I truly belong, I’m a little bit Greek and Armenian What’s your favorite childhood memory? Shucking pomegranates with my siblings, we had a beautiful tree outside our childhood home. Our little hands were always stained red. What’s your secret ability? I am pretty crafty – I make jewelry on the side as a hobby What is the furthest away from SLO you’ve been? I studied abroad in Rome, Italy and Madrid, Spain for a quarter – but I think Rome is the farthest Wallace Group Kylie Castle
