Since 2006, Harrison Edwards has supported RTK Environmental Group, serving as its outsourced marketing department. In that time period, the company has grown from a small, company serving Connecticut to one of the nation's largest and most-respected environmental testing companies. Our digital marketing team has led the charge in website development and coding, social media campaigns, and analytics. In terms of media relations, publicity has driven RTK's business growth. Since its front-page New York Times story on indoor mold  in 2007 to 2018's media push on the dangers of asbestos, RTK's business has grown more than 300%.
