Hello Los Banos!! My name is Shannon Zwilling and I am currently one of your Directors for the Los Banos Chamber of Commerce. I moved to Los Banos with my mom in 1995. I have been a volunteer for the last 8 years, but officially as an ambassador for the last 4 and most recently a Director. I've done the May Day Beer booth for the entire time I have been with The Chamber. I also volunteer for the Tomato Fest and Dads Night Out, the Fireworks Booth as well as an occasional Street Fair. I also bartend for the Mixers sometimes. Halloween 2016, we hosted a Halloween Costume Party at the DES Hall, hopefully we can do that again in the near future. I got into volunteering when a friend mentioned that the Chamber needed help May Day 2013 and I jumped at the chance. I had so much fun and I didnt want to stop. I continued to do what I could and when. If you know me, you know I talk a lot!! So for a chance to meet with the public during functions and interact with them, I just had to be involved. I love every minute I spend volunteering. I am currently working for the Los Banos Unified School district as a Paraprofessional for the LEAP Before and After School Program and have been there since 2014. I am overjoyed to be involved with the Chamber and cannot wait to see what the coming years bring our great town. I hope to see you all soon and meet you if I haven't already.
