"We are happy that John Jastrem has already joined ARCADIS and is willing to step into the position of CEO for our North American activities. He has a track record of profitable growth at Callison and his experience as a chief executive officer and senior executive at large global public companies, and as an entrepreneur in private organizations as well as his strong background and expertise in the areas of marketing, sales, corporate finance, and strategic planning all contribute to him being the right leader of our North American business," said Neil McArthur, CEO of ARCADIS.

"With Joachim we attract a proven strategic and operational leader in professional services with a strong track record of successful growth and transformation strategy development and implementation. He has a strong entrepreneurial spirit and is a proven team builder, who can rally people behind a goal and create results, which is exactly what we need in today's shifting market conditions in the North American market," McArthur added.

"We want to thank Gary Coates for his significant contributions to ARCADIS over the 25-year lifespan of his career with us. Early in his career Gary laid the groundwork for our Multinational Client program, which helped propel ARCADIS into international markets. In his role as COO and later on CEO/COO of the North American activities he has seen years of high growth and industry-leading margin performance. In recognition of the changing market conditions in North America, with the last two years forming a particular challenge, Gary initiated a transformation of the organization to position for success for 2015 and beyond. Gary will work with John and Joachim to ensure a smooth transition until his retirement in May and his legacy-building work will continue under the direction of John and Joachim."
