Profile bio

About Greg Josselyn

With nearly a decade of Project Management experience, I work collaboratively with my teammates on site to develop and implement a strategic plan to get our projects completed on time, and under budget. I am driven by the success of my teammates, and the personal and professional growth of those around me.Since 2014, I've founded three investment clubs, pooling contributions from members while making strategic investment decisions together. The team's primary focus is in equity investments in publicly traded companies and ETFs, but have also begun venturing into the private equity markets over the last three years. In 2015, I began a black walnut timber grove, hand planting nearly 600 trees in Vermont. This is perhaps the investment I am most proud of, and it represents my longest horizon investment vehicle with a potential return in 30 to 50 years. Though the returns are far in the future, I am proud to offset some of my carbon footprint while bringing back operations to a farm that's been in my family for nearly 300 years.In 2019, I became a co-founding and Chief Operations Partner of The Hypershield Partnership, LLC. in Boulder, CO. THP is an aerospace company dedicated to evolving with the growing commercial space industry and meeting the mission design, logistics and technology development services needed to realize the future of frequent atmospheric flight at or near orbital velocities. At THP, I've developed business procedures to help streamline operations, and created unified goals to support the greater mission. I am also tasked with creating new business opportunities, developing a cap. ex. program, and building investment strategies to maximize and support the team's rapid growth.

Listed skills include Submittals, Construction Management, Primavera P6, Autocad, and 28 others.
