Welcome CoreLink was originally founded in October 1980 by John and Linda Haesler and has successfully serviced the Orange County market for almost 30 years. Adecco NA acquired the CoreLink Area Offices in February 2006 as Premier Divisions of Adecco, for the purpose of building and expanding our business model to focus on regional vs. national client relationships and the recruitment of higher skilled professionals. Each division is staffed with dedicated recruiters that specialize in that functional area of expertise. Contact Us 36 Discovery Suite 250 Irvine, CA 92618 Phone: (949) 250-6565 Fax: (949) 752-8506
