Annual Open Enrollment
September 8 -19, 2025
Open enrollment is a great opportunity to explore and take advantage of the benefits that your employer offers. Without reviewing and making changes during open enrollment, you may miss out on important benefits or end up with coverage that does not fully meet your needs. Review your options below on how you can enroll at open enrollment.

Meet with a Benefits Counselor
Benefit Counselors will be available onsite to meet with you to review your benefits and assist you with any changes you need to make.
New Hires
As a newly hired employee, enrolling in benefits is a crucial step to ensure your well-being and security. *You have 30 days after your hire date to enroll. Failure to do so will delay enrollment until the next annual open enrollment.
You have two options to enroll in benefits: call center or self-enroll

REMEMBER: The Annual Enrollment Period is the only time you are able to make changes to your benefits.

If you should experience a Qualified Event, you have 30 days from the Event Date to make a change to your benefits.
