You can reach a customer service representative by web chat through the Grant Thornton Benefits Center website at digital.alight.com/grantthornton. You can also call the Grant Thornton Benefits Center at 1.833.476.2341 from 8 a.m. to 5 p.m. CT Monday through Friday. If you don’t connect with a representative right away, you will be given the option to save your place in line and be called back once a representative is available. Health Pros are also available to assist with tough issues like claims and billing disputes. Questions About Coverage? Start by contacting the insurance carrier directly. They know their coverage rules best. If you enrolled in a Bronze Plus or Silver medical coverage level, check out the HSA User's Guide (PDF) for additional contacts during the year.
