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.

Teri Customer Service

In touch with 10's of 1000's of our customers, and somewhow keeping them all exceedingly happy. When she needs a bit of release she heads out on the backroads on one of her classic motorycles or walks out back to feed her continuously growing flock of chickens.

Brittany Industrial Design

Soft models, hard prototypes, and compelling visuals - Brittany makes our products approachable, enjoyable and beautiful. Color chief, laser cutting technician, and photo studio director. Did we mention that her laugh is infectious?

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.

Jocelyn Product Management

Bioengineer, global health technologist, clinical trial monitor, and inventor of the Pumani bCPAP. Former resident of Malawi, she's traveled more dusty back roads then she can remember.

Farshad NPI and Operations

He keeps our operations moving, our suppliers on track, and our systems connected. Equally comfortable on a factory floor or linking together the latest cloud enable infrastructure component, Farshad takes our products from prototypes through production with panache. To 'relax' he can be seen on the SF Bay catching air on his kite board.

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!"

Katharine Product Engineering

Prototype development, mechanical engineering, data acquisition and systems analysis. Throw in a little javascript and mean sketch pad capability and you have a fully rounded product designer. Can be found on the weekends perfecting her chocolate chip cookie recipe.

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.

Lauren Social Media and Marketing

Ping, Zap, Boom! When we have something good to share, Lauren lets the world know about it through all channels. Equal parts story teller and opera singer, Lauren uses her voice – in person and over social media – to broadcast our news on a daily basis.
