CEO: Dean Park

Makes electronic identification tags for fish and wildlife study.

Because Biomark believes cross-training and variety make for higher job satisfaction, all employees have the opportunity to do fieldwork and get their hands dirty tagging fish and animals. Staff members from the CEO to the customer service reps tag salmon with the staff biologists. When choosing his new company headquarters, CEO Dean Park passed on cheaper options and chose a location to minimize commuting time (and maximize the number of employees able to bike to work).
