Andrew Byrns, SASH Program Associate

Andrew Byrns, SASH Program Associate

Andrew grew up in the Bay Area. His parents noted that even from a young age he spoke in prophetic form. Andrew traveled the world picking up German, Russian, French, and English allowing him to translate his sage advise into many languages. After years of drafting fortune cookie fortunes he developed a serious case of writers block. A search for a new profession led him to join GRID Alternatives as our SASH Associate. When asked if he misses his sagely days he drew a pensive face and replied, "Eh, I guess that's the way the cookie crumbles."
