Meet Our Team

Mario Bogdan

Mario, founder and CEO of BC Mechanical Design, has 20+ years’ experience in product development. He is the co-founder of several product and technology firms and has deep roots in Silicon Valley. Never satisfied, Mario works on improvements wherever he may be. You’ll always find him with a sketchbook, working through design issues on any flat surface he can find. This pursuit of perfection is contagious and drives our team to achieve. In the rare moments Mario is not working he enjoys hiking, fishing, music festivals and socializing.

Craig Brinton

As a career designer, entrepreneur, and co-founder of several design related businesses - Craig’s widely varied background brings a wealth of experience to BC Mechanical Design. He has worked on consumer products, commercial furniture and fixtures, restaurant and club design, and engineering and manufacturing large-scale public art and exhibits… all the while owning and operating several wildly successful nightclubs in San Francisco. He received a B.S. in Mechanical Engineering from San Francisco State University, graduating at the top of his class. Craig is an avid cyclist, competing in road and endurance mountain-bike races.

Stephen Coffer

As a mechanical engineer at BC Mechanical Design, Stephen strives to create effective product solutions to help clients exceed expectations. Stephen’s academic background, which culminated in a master’s degree from UCLA, helps him create informed design solutions. After graduating he developed his engineering skills while working on production machine design for large customers, including Microsoft. Outside of work Stephen is an avid rock climber, spending at least three days a week at the climbing gym and most weekends at one of California’s many world-class climbing areas.

Dan Weber

Dan moved to the Bay area from Orange County in 2009 to finish his degree in Mechanical Engineering at San Francisco State University. He got his start in the world of product design early in his college career while working at one of the largest NSF funded 3D printing labs. He honed his design and fabrication skills both inside and outside the classroom, and joined BC Mechanical Design in 2013. Dan developed a strong intuition for elegant and efficient mechanical design from a young age and strives to find creative ways to solve complex problems. Dan enjoys modifying his car and motorcycle for the race track, and when he’s not working you can find him surfing, snowboarding, mountain biking, or rock climbing.

Thomas Hoye

Thomas grew up in Phoenix, Arizona and attended Santa Clara University where he received a B.S. and an M.S. in Mechanical Engineering. While there, his studies focused on mechanical design, aerospace and systems engineering. As an undergraduate he led a team of thirteen engineers to design, fabricate and test a CubeSat nanosatellite. This work led into his time at SCU's Robotic Systems Laboratory where Thomas worked as a satellite operator for NASA Ames Research Center. Outside of BC Mechanical Design he is an avid musician and plays several instruments, writes and produces music, and DJs.

Felicia Frans

Felicia is a recent graduate from Santa Clara University with a B.S. in Mechanical Engineering. She has always loved to tinker and take things apart to see how they work, and now enjoys the challenges of doing it professionally. Felicia has been a part of the Intercollegiate Baja SAE project and an airship restoration project with the Moffett Field Air Museum. Outside of work, she enjoys challenging herself to learn a new musical instrument, picking up a new language, or trying a new sport. Felicia enjoys watching movies, playing basketball, relaxing at the beach, and snowboarding (or attempting to) during the winter.

Cheyenne Lopez

Chey rocks the office manager and executive assistant scene with her infectious energy and amazing attitude. She loves to engage in all aspects of BC Mechanical Design and continually takes on projects outside of her job scope. A native of Mariposa, California she studied Business Management with a focus in Marketing. Some seasonal favs with family and friends include Winnebago cruising, hiking, camping, fishing, snowboarding, concerts and watching birds with her kitties. Whether working as a Les Mills Bodypump instructor-in-training or as an Office Ninja®, Chey’s true flow is creating an atmosphere where people make meaningful connections.


Luna is the most important member of the BC team. A master at her craft, she keeps the team focused, determined and creative. Her wealth of experience with herding and leading multi-disciplinary groups is invaluable. Quick to sniff out potential problems, she shortcuts the design iteration process by fetching pragmatic solutions from thin air. Without Luna’s expertise and guidance we could not achieve our consistent high-level of quality and creativity. When not on the job Luna enjoys daily puppy park visits, and weekends often include Sierra backpacking adventures or exploring beautiful California beaches.
