Our work is varied, spanning from consumer products aimed at mass markets to medical devices intended for use in developing country applications. Our aim is to use the power of design to improve lives everywhere and be mindful of our impact.


Robert CEO

Our fearless leader and Designer in Chief, Robert brings a mix of mechanical and industrial design chops, business savvy, and unbridled optimism. He founded 3rd Stone to be a vehicle for the power of design in solving life's persistent problems. During his 20+ year career he has earned a lot of patents, been responsible for more than a few product successes, and learned a good story or two. On the weekends he works out the cobwebs by maintaining an even cadence of 88 rpm on his bicycle.

Caroline Marketing and Sales

Health Educator, E-Commerce Master, and Food Stylist. Being the soul of PlanetBox, Caroline truly wears many different hats. Figuring out new media tools, developing unique product partnerships, and changing our customers' lives every day is what she does best. In her rare shots of time off she enjoys hikes on Mt. Tam and watching her daughters dance and do martial arts.

Shonalie Finance

Cash flow, balanced accounts, and hopefully more profits than losses, all matters financial fall under her pervue. Equally comfortable detailing international payment structures and annual operating plans, she does it all with aplomb. On a good day you'll find her racing her two dogs to the beach.

Jim Mechanical Engineering

Principal engineering talent with a winning personality, Jim brings almost 20 years of medical device development experience to the table. Expertise in injection molding and mechanism design. Formula 1 wannabe.

Jackie Mechanical Engineering

CAD Master, Aero-Mechanical Engineer, Controller of our Design Intent, Jackie keeps us all *very* technically organized! Adept in analysis, prototyping, and simply being clever. Cat enthusiast.

Danica Product Management

How do we deliver the best possible customer experience, combined with award winning product solutions – that’s where Danica comes in. Self-described medical device enthusiast, she manages every commercial aspect of our products. With years of experience training, selling and representing medical device efforts in Southeast Asia, she is as comfortable in a NICU as she is in the sand pit with her volleyball team.

Chris Quality and Regulatory

Assuring our success while keeping our outputs consistent, compliant and up to code – the CFR code that is. Then consider a few numbers like 13485, 60601 and 14971 and you have a full day’s work for Chris, our regulatory guru. And if you worry that you might get stung by our onerous SOP’s, never fear – he’s a pro with honey bees.

Li Supply Chain

How do you get product from A to Z? Just ask Li. He keeps our suppliers moving fast, our shipments en route, and everything else on time. Just as he enjoys crunching numbers and running spreadsheets, he also savors the sound of snow crunching under his board as he runs the slopes.

Brett Engineering

Gears and motors, sensors and testing, Brett’s our master of assembly. He puts together our crazy contraptions and sets them in motion like finely tuned clockworks. In his free time he builds all manner of electric vehicles because to this guy, ‘PTO’ doesn’t mean Paid Time Off – it stands for Power Take Off!

Mark Operations and Logistics

There’s something about someone who can be counted on to make the trains run on time – and the trucks, ships and planes just for good measure. Mark makes sure our operation run smoothly and the goods get delivered as planned. When he isn’t connecting the dots of the international supply chain, he lets the waves carry him on his stand-up paddle board off the Sonoma Coast.

Keith Electrical Engineering

Circuits and Schematics, Firmware and PCB's. If it carries current Keith can make it go. As a weekend scientist he volunteers at an observatory and loves the moment when a kid looks through a telescope for the first time and says "wow!"

Brett Product Development

From one to many, from process to product. Brett B is our go to leader for all matters that require taking new concepts all the way across the finish line to producible product. Equally at home reviewing project plans, mechanical layouts, or software specs, Brett clarifies the essential requirements of each new development effort and delivers winning solutions. In a previous life he designed animated lights for the top of the tallest building on the West Coast. And he can play ‘All Right Now’ on the clarinet blind-folded.
