Our Team

Sarah Nelson
Executive Director

Sarah has worked on food-related projects in the Bay Area since 2008. She launched Cooking Matters in the Bay Area in 2010. In her previous work with Bay Area farmers' markets, she created the Bay Area’s first Market Match program, which gives farmers’ market customers who use food stamps extra funds to spend at the market, and a Veggie Rx program that helped diabetes patients increase their produce consumption and positive health outcomes. In her youth, she taught yoga and guided bicycle tours in France. In 2011, she founded the nonprofit Three Squares, which merged with 18 Reasons in 2013. She is passionate about cooking, rock climbing, riding her bike, and, yes, her job. She lives in San Francisco with her partner and two daughters.

Claudia Guererro
Operations Director

Claudia is a strong believer in the ideology that the kitchen is the heart of the home. Her Hispanic background fosters her love of food and culture, and she is especially inspired by the example set by her late abuelita of making home-cooked meals a priority. She completed her B.Sc. in Health Education with a Certificate in Holistic Health Studies at San Francisco State University where she spent most of her time researching issues surrounding food justice. During her time at SF State, she was part of the Community Food and Justice Coalition, where she conducted research on food policy and served on the planning committee for the All-In initiative working to end poverty in Alameda County. When she is not enjoying the company of her wonderful colleagues or class participants, you can find her trying out new recipes at home, practicing yoga, hiking, or on a fun road trip!

18th Street Kitchen

Theresa Salcedo
18th Street Kitchen Program Director

A native of Virginia, Theresa's curiosity in food was nurtured by her family, which includes talented cooks, farmers, gardeners, and fishermen. When she moved to the Bay Area in 2013, Theresa became a passionate volunteer with both our 18th Street Kitchen events and Cooking Matters program. She joined the team full time in 2015 and is eager to have everyone walk through the doors of the 18th Street Kitchen and feel connected to their neighbors, friends, and food. When not in the kitchen or at the farmers' market, you can find Theresa reading at Ocean Beach or getting lost in museums.

Gracie Schatz
18th Street Kitchen Chef & Culinary Manager

Gracie Schatz has been in the food industry for over fifteen years. In her career, Gracie has worked in a variety of places: as a baker and private chef in Eugene, OR, farming and cooking in Italy, raising pigs in the Sierra Foothills, butchering at the Fatted Calf in San Francisco, managing Avedano’s in Bernal Heights, cooking at Bay Area restaurants Molina and Cala and her own pop-up restaurant, Bread and Bones Supper.

Elise Hayashi
18th Street Kitchen Associate Director

Born and raised in Colorado, Elise grew up in a family where knowing how to use a paring knife was more important than riding a bicycle. This sparked her passion for food and cooking at an early age, and she enthusiastically relocated to the Bay Area to study nutrition science at UC Berkeley. Outside of the classroom, Elise helped implement childhood obesity and exercise research, and worked as a pastry assistant to fill her free time with galettes and mousses. She also broadened her experience with food by studying and cooking her way through the Mediterranean diet in Italy, and working on an organic farm in Japan. Now, she is excited to merge her gastronomic backgrounds, and lean into her Japanese and Korean heratige to share her love of food with the 18 Reasons community. During the rare moments when she is not eating, Elise can be found trying out new sports, playing and listening to live music, or wandering the aisles of grocery stores and farmers' markets.

Alex Bitker
18th St Kitchen Assistant Program Manager

Alex can’t remember a time in her life when she wasn’t excited about food. Her father, a professional chef, brought his talents home and helped her foster a love and curiosity for all things culinary from a young age. Following in his footsteps, she began working in a small bakery in her home state of Connecticut, eventually making her way to San Francisco where she’s dabbled in everything from creating cakes and custards, handmaking fresh pastas, to curating chocolate + spirit tastings. Alex believes in the transformative powers of food, and that it is never too late to get started in the kitchen. She’s thrilled to be a part of the 18 Reasons team and share her passion for food with her Bay Area neighbors. In her free time Alex enjoys reading, exploring the city's hiking trails, discovering new music and going to live shows, and of course, cooking.

Emma Hodson

She has also spent significant time abroad in Latin America, both through travel and working on youth leadership initiatives in the Dominican Republic.

Shay Stoklos
Community Programs Manager, San Francisco County

Shay's friends and family know that no visit is complete without collaborating on one veggie-heavy meal. Born and raised in Los Angeles, Shay always loved a messy cooking project, but it wasn't until attending UC Santa Cruz that their passion for growing food, and more importantly, connecting with others over beautiful produce, was sparked. Shay has spent much of the last 5+ years working for organic vegetable and flower farms, simultaneously training college students on broadcast radio production at a community radio station. She's passionate about food justice, connecting through food, and community building. When Shay's not making a Dutch baby pancake, chili crisp, or ramen, they're probably at the farmers market, running, singing, or dreaming up DIY home improvement projects.

Abby Suster
Community Programs Manager, Alameda County

Abby has always had a passion for eating good food, especially as a child when she would join her grandma and mom in the kitchen making classic Hawaiian, Asian, and Mexican dishes, a blend of her family's cultures. Abby has worked with 18 Reasons for years and served a variety of different roles. She graduated from Santa Clara University with a major in Environmental Studies and minors in Spanish Studies and Sociology. As the Assistant Program Manager for Alameda County, she enjoys connecting with her community over a yummy plate of food, teaching hands on cooking techniques, and giving folks a space to feel comfortable being their full selves.

Helena Zindel
Assistant Program Manager, San Francisco County

Helena's work at 18 Reasons is driven by her belief that access to nutritious and affordable food is a human right. Helena grew up in Sacramento, California, where she discovered the power of food as a means of creating community and expressing her care for others. She owes her love of cooking to her parents, both talented cooks themselves, who gave her a cookie cookbook for her tenth birthday. She went on to bake every single recipe in the book, requesting a new cookbook once she'd finished. Her work as a chef and culinary arts educator with Soil Born Farms ignited her passion for teaching cooking in community settings. Helena continued to pursue her passion for food justice while working to increase food access & security for newly arrived refugees with the Internal Rescue Committee. She received her Bachelor's degree in Sociology from Whitman College in Walla Walla, Washington, and uses her background in social science to inform her approach to fighting for food justice. When she's not busy making a big pot of beans or baking sourdough loaves for her neighbors, Helena can usually be found catching up on cookbook reading, making friends with the neighborhood cats, bike riding down JFK drive, and eating super burritos in the Mission. Helena is someone who passionately believes in the power of good food in changing people's lives for the better and is thrilled to be a part of the team at 18 Reasons. 

Mauricio Guerrero-Villanueva
Assistant Program Manager, Contra Costa County

Growing up, Mauricio was aware that diabetes was prevalent in his family, starting with his grandparents. When his father was diagnosed as a pre-diabetic, his family altered their diet and lifestyle to support him. As his father’s condition improved, Mauricio realized the importance a healthy diet has on one's health. A couple of years later, Mauricio obtained his degree in Clinical Nutrition from UC Davis. At UC Davis, he was a part of the Knights Landing One Health Clinic and became the first Health Education Chair. Mauricio and his colleagues implemented the clinic’s health education program, which consisted of appointments and an array of workshops for their patients. Mauricio noticed many similarities between the Knights Landing community and his neighborhood in Oakland, such as the lack of fresh food and access to resources regarding health education. Recently, he obtained his Master’s of Public Health, and through 18 Reasons, he hopes to make a difference and make these resources more accessible to the people in his community. Mauricio enjoys watching sports, running, trying new food places, and relaxing with his cat during his free time.

Wilmer Ruiz
Assistant Program Manager, Food As Medicine

Wilmer's love for food ignited over hearth-cooked beans and home-raised-and-slaughtered lamb, instilling in them a deep appreciation for food as their family's foremost expression of love. Descending from Nicaraguan and Tapatio heritage, Wilmer was raised in Paso Robles, nestled within California's famed wine country. Growing up, access to culturally relevant cuisine was a rare luxury. They have experience as a children's developmental therapist, selling cheese at farmers' markets and taprooms across Los Angeles, and stints in the Bay Area's essential fine dining establishments. Wilmer pursued Anthropological Linguistics at CSULB, delving into hegemonic theory and the manipulation of language by societal and governing structures. Amid the pandemic's upheaval, Wilmer, like many, grappled with feelings of marginalization and frustration toward authority. In light of these experiences, coupled with the urgency of climate change reshaping our food landscape, Wilmer sees a source of kismet with 18 Reasons. They view this as an opportunity to intersect their passions between community engagement and for food. You'll find Wilmer shucking Bay Area oysters, embracing being a novice climber, indulging in poetry, or thinking of and doing a lot of nothing.

Kali Haire
Program Coordinator

Growing up in a single parent household, Kali was most familiar with fast, convenient foods and rarely ate home-cooked meals for most of her life. While attending school at Occidental College in SoCal, she learned the importance of food in relation to the body through her kinesiology classes and began to learn how to cook. Through cooking and growing food for herself, with friends, and with a community coalition called Food Justice House, Kali found joy, community, and empowerment through the power of home-cooking. Additionally, Kali focused on ways to improve her campus community through access to health resources and lead the implementation of free menstrual products in campus bathrooms. After college, Kali continued learning about local and sustainable food systems through WWOOFing on an organic farm and working with local CSA (Community Supported Agriculture) farms. Her true passions lie within the intersection of increasing access to health resources, building community, and learning about holistic ways of healing. Through her work at 18 Reasons, she hopes to empower folks with the education and resources to help them along their healing journeys and ignite the same passion for cooking that she has found.

Aunts, uncles, cousins, and friends gathered weekly to share stories about life while working together to craft the evening dishes seamlessly. It was around that Sunday dinner table that she fell in love with food and its ability to bring people together. Mackenzie brings a warm and welcoming energy to 18 Reasons and strives to bring the same sense of belonging that she felt in the kitchen surrounded by her family to all of her classes.

Erika Velasquez-Lopez
Program Coordinator

Erika was born and raised in Oakland, California. She graduated from San Francisco State University with a B.S. in Health Education. She has always had an interest in Medicine and learning about the many ways one can take care of their well-being.

She noticed that some common health conditions were Diabetes and Obesity, that correlate with people’s lifestyle and eating habits. As someone who has family members with these health conditions and has seen the significant importance of how changing eating habits can help reduce and possibly heal from these conditions, it has inspired her to be a part of this organization, educate herself and her community on how to take care of their well-being through cooking and nutrition.

Case Vanderburg
Program Coordinator

Case is a recent graduate from the University of San Francisco’s Master in Public Health program, whose interest in cooking began with the 2020 Covid pandemic, giving him plenty of free time to look through his family’s saved recipes and prepare surprise feasts for them. He is firm on the belief that everyone deserves to look and feel their best, and that one of the best ways to do this is through food. Providing interactive learning experiences to families is powerful and can completely reshape dining, shopping, and other lifestyle habits. When fresh fruits and vegetables are shopped for, seasoned and prepared with love and insight, they can easily be the highlight of any dish, and provide your brain and body with all the nutrients and flavors they crave. His favorite activities in the world include ecstatic dancing, afternoon jogs through GGP, socializing over some kava tea, reading sci-fi thrillers, fusion cuisine, and meal prepping (black bean hummus and kimchi breakfast burritos, anyone?)

As Mike wrote to us in his cover letter seven years ago, “The satisfaction of impacting the lives of students through culinary education and fantastic food is what drives me, and makes this profession more than a career; it is the way I lead my life.”

Chef Mike’s passing in 2023 was a great loss for our whole community and we miss him dearly.
