Berg’s formal teaching career began at the University of California in Los Angeles. He went on to teach at Stanford University from 1967 to 1974.[9] While there he published a book, Early Virgil,[10] along with several articles on Greek myth, anthropology, and religion,[11] and led a student archaeological tour (Stanford-In-Greece) in the summer of 1974, where he witnessed the momentous fall of the Greek military junta and the return of those they had exiled.
Since 1975 Berg lived in Gearhart, a small town on the Oregon coast, where he won election to the City Council and helped draft its Comprehensive Land Use Plan, organizing and directing resource inventories, surveys, and data analysis. As a result of this planning activity, Gearhart was able to avoid an expensive municipal sewer and completed an award-winning solar retrofit to the Fire House.[12] The first edition of his history of Gearhart was published in 2001.[12][13]
Berg has kept up his studies of ancient Greek and Latin, occasionally publishing new material, including an e-book translation of Philogelos, the world’s oldest extant joke book.[14][15][16] In 1987 he took a teaching position at St. John’s College in Santa Fe, New Mexico.[17] Lured away to the Kingdom of Tonga by a Fulbright Lectureship in 1989,[18] he spent the year teaching and gaining new insights into ancient philosophy from Futa Helu, founder of ‘Atenisi University in Nuku’alofa. Before returning to Oregon, he assisted Futa in completing a ground-breaking work on Heraclitus.[19]
Since 2005, he was a member of Translatum Forum, where he served as moderator of the ancient Greek and Latin boards.[23] This activity has sustained and enhanced his familiarity with the modern Greek language, as may be evidenced in Berg’s translation of Romiosini by the revolutionary poet Yiannis Ritsos, which was published in 2014.[24][25]
