Promoting and encouraging technical, scientific and artistic skills through social collaboration, education and individual projects.


Ace Monster Toys (“AMT”) Makerspace is a 501(c)(3) non­profit member supported organization founded in 2011. We support traditional makers and craftspeople as well as hackers both digital and material. Our community brings together people of diverse skill levels by providing resources and culture to build networks; co-work; and engage in projects that benefit individuals and the community at large. The resources we develop include spaces and a wide variety of tools and supplies to support making and learning.


Supporting our mission is met with more than just space and tools. We hold the following values as integral to our success:

We are intentionally growing a welcoming community of diverse people with an economically accessible offering. We bring together makers, craftspeople, hobbyists, entrepreneurs, programmers, creators and hackers in Oakland, CA and the greater East Bay.
The spirit of curiosity is at the heart of hacking, our culture of camaraderie makes for a welcoming place for those who are willing to try something new or ask how things work
Sharing expertise, ideas and knowledge is what makes growth possible as a community, individuals and professionals
We promote an environment of cooperation where conducting ourselves with respect for each other and the space is expressed though active transparency and communication


Board of Directors

Chris O’Sullivan

Chris leads an handyman and kitchen remodel consulting team for local realtors. They focus on energy, lighting and space efficiencies and clearing project roadblocks. He has brought that experience, expertise and enthusiasm for building to AMT for the last several years when he has found himself on the West Coast. A semi-reformed serial and mass entrepreneur he provides advice to Presidents (startup presidents that is) and founders as another facet of his career.

A builder and an entrepreneur at heart, Chris is thrilled to be adding his personal and professional skills to the AMT MakerSpace team.

Pierre Grandin

Pierre joined Ace shortly after relocating to the Bay Area. Initially interested in the Raspberry Pi meetup, the amazing culture of sharing knowledge quickly led him in learning about many of the tools that are available at Ace, from the big CNC router to 3D printing, and, of course, laser. After two years of membership, learning from others, he became more involved in running the space by helping wherever his skill set could be of use.

Nicole Scherm

Nicole has been a member at AMT for roughly a year. They are working towards using all the tools at AMT, and can often be found working on multiple projects at once. After finding AMT, they were drawn in by the friendly community and decided to run for the board. They have a long history of volunteering and coordinating groups and events. As a board member, they’re excited to participate in outreach to local groups and help the AMT community grow. When they’re not spending their free time at AMT, they enjoy dancing and being involved in circus communities.

Jacob La Bay

Jacob has been a member for little over 6 months. Some of his project include 3D printing tactile maps and robot building. His ambition is to build a ‘bot to feed his cats treats and praise them. He key interests while serving on the board include expanding our revenue beyond member fees. He brings over five years experience raising funds for Berkeley Humane Society to the table to further those goals. When not busy with his delightful cats Beaker, Diego and Mrs. Whiskers or robots Jacob enjoys reading and writing.

Mark Johnsen

For over a year, Mark has been a part of the AMT community, learning and developing his skills. From his humble high school beginnings as a Tuba player, he has since traded his brass pastime for high-powered laser cutting, CNC milling, and father-son BoxBot building. Mark is eager to see who and what comes through the door and is happy to meet new people and machines. He’s seizing his opportunity to expand and secure the future of AMT.
