In a media release from General Shale, Green said the time is right for him to retire, and expressed confidence in the company’s potential for future growth.
Green joined General Shale in 1973 as a management trainee. He was promoted to manager of the Knoxville brick plant and worked his way up to the title of regional production manager with the responsibility of overseeing several manufacturing facilities.
In the early 1990s, the board appointed him vice president of marketing, then moved him up to the executive position in 1994 where he has served since.
During his tenure at General Shale’s helm, Green has seen the purchase of the company by Austria’s Wienerberger Group in 1999 and the shuttering of the Johnson City plant in 2009.
In the past few years, the company has been purchasing existing manufacturing and mining facilities.
After his April 1 retirement, Green will act as a consultant to Wienerberger Group’s managing board.
Charles Smith, General Shale’s current president and COO will succeed Green as CEO.
