Common questions
Answers before you even ask.
Do your services cost me anything?
No. As independent brokers we’re compensated by the insurance carriers — our guidance, plan comparisons, and enrollment help come at no additional cost to you.
When can I enroll in or change a Medicare plan?
Most people enroll during their Initial Enrollment Period around age 65, or during the Annual Enrollment Period each fall. Certain life events may qualify you for a Special Enrollment Period — we’ll help you find out.
What’s the difference between Medicare Advantage and a Medicare Supplement?
Medicare Advantage usually costs less to own and potentially more to use, while Medicare Supplements cost more to own and generally less to use. We can walk you through more differences — which one fits is defined by your specific medical needs.
