The International Society for Trenchless Technology (ISTT) has announced the appointment of John Hemphill as its executive director, succeeding retiring executive secretary John Castle, effective June 1. Hemphill recently stepped down as executive director of the North American Society for Trenchless Technology (NASTT), a position he has held since 2000. The NASTT is one of the largest national societies affiliated to the ISTT which, under Hemphill's guidance, has consolidated its position as the leading trenchless technology organization in the region. Hemphill, with an eye on further growth in the civil engineering utilities sector, has expanded the educational services that the NASTT provides and has established the annual North American No-Dig Show as the major trenchless event of the year for the underground utility community of North America.
