Who We Are


Sophia Lorenzi ·  Founder + Director

It all started with gelato. My first job at 15 was scooping gelato at the local mall, and I’ve been hooked on delivering people joy through food ever since. For over 15 years, I’ve worked too many jobs in food and hospitality, from steaming milk as a barista to teaching kids how to cook. I also wrote about Bay Area food trends for publications including 7x7 Magazine, Eater SF, and Flaunt. And because I just couldn’t get enough food from cooking it and writing about it, I led food tours in SF with Edible Excursions for several years, so I could talk to even more people about food. The cooking, the writing, and the talking (not to mention all the eating) eventually led me into consulting, producing events and designing custom culinary itineraries for tech companies, luxury travel agencies, and non-profits. Fun fact: one summer I created and produced over 90 cooking classes for kids in 9 weeks of summer camp.

Currently, I serve as an advisor to the The Cooking Project, a non-profit that teaches at-risk youth fundamental cooking skills. I also create monthly events as the Events Director for The Proof Collective, a Bay Area-based community of women who live, love and work in food.

Somewhere between processing rabbits in Crete and slurping hột vịt lộn in Saigon, I realized the two things I like most are: 1) bringing people together around food and 2) collaborating with passionate food people to make that happen. This is why I started HØSTE.

Joshua Clever · Natural Chef, Dining Experiences

If six years of living in Paris taught Joshua Clever anything, it was appreciating seasonal, local and sustainably grown food. Highly influenced by the therapy and value of a whole foods diet, Joshua decided to return to California and pursue a career in the culinary arts. He became a certified Natural Chef at Bauman College in 2008, a culinary program based on holistic nutrition and married his two passions, food + yoga. After working years as a private chef under his own company, Urban Provisions, he decided to bring a third element into the mix, wine. Life is about balance and for Joshua, yoga + food + wine is the perfect combination to achieve just that. Joshua continues to work as a private chef, co-hosts yoga retreats down the California coast, leads health & well-being inspired culinary classes, and offers food + wine pairing events in the Bay Area.

Vanessa Silva · Chocolate 101 Expert Facilitator


Vanessa’s curiosity around food started very early at her Italian grandmother’s kitchen, rolling gnocchi and making aioli before she was 10 years old. She went on to study Food Engineering, Holistic Nutrition and has founded and ran a few food-related businesses. The first one started while she was in college: a chocolate confection and artisanal chocolate Easter eggs. A few ventures later, these days Vanessa can be found running a culinary program for kids in San Francisco, where she shares her passion for eating and cooking with kids 2-12 years old. 

Vanessa is Brazilian and uses that as an excuse to unapologetically exaggerate the flair and vivacity that she brings to her classes and to life in general.
