About the Bake Sum Team





Joyce is a Bay Area native and worked in Silicon Valley for nearly a decade before she decided to focus on pastry. She founded La Chinoiserie and has partnered with many local coffee shops to supply pastries. La Chinoiserie and Joyce have been covered in publications like, the SF Chronicle, NPR and on KTVU.  

In 2020 during the pandemic, wholesale pastries and coffee business both completely changed and forced us to make multiple pivots, but Joyce's love for pastries never waned. One of such pivots was the Bake Sum Box, filled with delicious, seasonal, fresh pre-packed pastries. It allows us to keep socially distanced, continue to make delicious pastries and get them into your bellies faster. 

Ari is a born and raised Bay Area lover of food, art and people. Their journey with Joyce and Bake Sum started when they were introduced to the world of “specialty” through third wave coffee. In their nearly 10 years as a coffee professional, Ari worked as a barista, manager and marketing consultant before deciding to take a sabbatical to study the migration of spices throughout history with the ultimate goal of fighting to decrease the inequities within business chains of coffee and food alike. In their spare time, Ari enjoys studying ceremonies and traditions of foods, baking vegan delights and jumping in & out of photojournalism.

Vanessa loves to make things with her hands as a means to explore the world and the many connections within it.  She considers herself a baking dilettante with an eye for the Arts, an ear for music, a nose for trouble, a mind for stories and philosophical musings, and a heart for all living things.  She lives in the Bay Area and doesn't plan on ever leaving it.





A South Bay native, Jay has always been fascinated by the process, history and the design of all things. His love of baking and cooking started since he was kid, and as an adult he takes a serious approach coupled with a silly nature when it comes to his craft. When he’s not in the kitchen he enjoys being lazy with his two cats, reading, and nerding out to anime, baseball, video games and other Asian pop culture.


Born and raised in San Francisco, Rangsiwan is lucky to still able to call the city her home. Despite growing up in her family’s restaurant, her personal interest in food didn’t begin until well after college. Little did she know that her obsession with recreating a simple cupcake would develop into a joy and love for producing and creating desserts for all to enjoy. Prior to Bake Sum, Rangsiwan was a weekend home baker, bringing cakes to family and community celebrations and various sweet treats to her colleagues at work and fellow fitness enthusiasts at her neighborhood gym. 


Morgan is our resident craftsperson when she isn't spending time with her Great Dane, Harley. Born and raised in the East Bay in Antioch, she's also a recent UC Berkeley Alumni and Math Major. She loves running almost as much as she loves confections. Go Bears!  

Joyce started Bake Sum in 2020 just in time for the pandemic making pastries and sweets that represent their upbringings. We love all things leavened, fluffy and delicious and utilize our skills as pastry chefs to bring you memorable pastries. We believe that pastries should be fun, beautiful, creative, and above all delicious.

The word "Sum" or 心 has many meanings and when translated directly into Cantonese Chinese it means heart. Sum also represents the addition of two or more things, people and/or ingredients. With Bake Sum, we share with you a little piece of our hearts in each pastry. We hope to meet you soon.
