About Us

This is the story of two designers with a big dream.

Tinkering Monkey first started as a blog to share our love of making things. We turned it into an online shop when people started to request the items that they saw us make. From the start, we promised ourselves one thing - to work with our hands and make things in small batches.

Everything you see in our shop was designed and carefully built by us‚ right in the garage of our tiny, century-old house our historic work/live loft in sunny Oakland, CA. Love hand-crafted goods built to last? We’ve got lots to share.

The Monkeys


Mike Cheung

Co-Founder, Production
Mike is a DIY enthusiast that believes that if something can be built, modified, or invented, then it should be. Mike grew up in Georgia shootin' guns and cow tipping, but now lives a much safer life as an industrial designer in the San Francisco Bay Area.

Paula Chang

Co-Founder, Operations
Paula runs the monkey business and connects with like-minded people in the design and DIY community. On the rare occasion she's not geeking out in front of the computer, she can be found either baking, disco dancing, or talking to the rabbit.

Eunice Hernandez

Sales and Support
Eunice Hernandez recently joined our team, and expands our tiny studio to a whopping three people. Contact us anytime, she'll likely be the first to answer your questions.

The Studio

Tinkering Monkey is located at The Cotton Mill, a brick-and-timber warehouse space in Oakland, CA. The warehouse was originally a cotton mill that began in 1883 and became the largest textile mill operation west of the Mississippi. We share the building with an eclectic group of artists, designers, and businesses.

Fun fact: We live where we work. Our loft is zoned for commercial and residential use, and there's a single wall separating our workshop from our living space. Not a bad thing when you love what you do for a living.
