Chelsey enjoys spending time with family, she and her husband Zach stay on their toes with their two young children Brinley and Reid.



In the almost 35 years I’ve been in Human Resources leadership positions – including stints with two Fortune 100 companies- I’ve never had the pleasure to work with a group of men and women like the ones at Advantage Benefits Group who so consistently meet and exceed our expectations in providing timely and effective guidance in the administration of our benefit plans. I heartily recommend them to any other organizations seeking to establish a more effective relationship with their benefits agents.
