Executive Board of Directors

Sceye, Inc
Over the past 2 decades I have had several board seats in both membership-based organizations and organizations seeking to shape the regulatory and normative landscape. This experience has provided me with relevant qualifications to serve on the HAPS Alliance board as I’ve likely experienced most of the challenges the board will be faced with.
My interest in joining the board of the HAPS Alliance is to use my experience in providing appropriate governance and offering an eye-on-the-horizon as the HAPS Alliance harvest the collective powers of it’s members to change the normative landscape, and make HAPS in the stratosphere as normal as cars on the road or ships in the sea.
