Having spent more than 20 years convening a community for civic engagement and innovation, Grace has now set her sights on collaborating with a team of small business owners and startups in the Bay Area to provide economic growth in the region while maintaining a unique perspective for growth and prosperity for all. The multi-dimensional landscape speaks to her willingness to allow the property to evolve into that which everyone is welcome and a sense of belonging is cultivated on a daily basis, all while having a good time outdoors.  

Her work as Co-Founder of Make Startups and fueled her ambition to support entrepreneurship across the country and advocate for national policy endeavors that allow the intersection of venture capital investing and philanthropy to collide for generational wealth for leaders and learners, funders and founders. Asombrosa was established to further the cause for future collaboration and gathering.
