Carl Zeiss Vision has named Randy Dannewitz as senior director in charge of North American sales and operations, following the departure of Darrell Zoromski who is now reportedly pursuing an opportunity outside the optical industry. Dannewitz's former position as U.S. director of sales and marketing will be filled by David George, former sales director for the eastern part of the USA. George's former responsibilities will be handled by Gary Shepson, who will remain in charge of sales in the western part of the country.
