I Can't say enough positive things about Peterka Insurance Company. They've been an incredible help in choosing the right supplemental insurance for Medicare, along with a Part D drug plan that perfectly fits my needs. Their entire team is highly professional, genuinely caring, and consistently goes the extra mile to ensure everything is on track. They follow up regularly, not just once a year but every so often, to check in and make sure everything is going smoothly. I truly appreciate their dedication and would highly recommend them to anyone looking for top-notch service.

Q&A with Diana Ngo
What are the reasons why I should work with a Medicare agent?
Answer: Medicare agents are independent brokers contracted with multiple insurance companies, so they can represent a variety of plan options and help you compare plans that fit your needs. There's no cost to work with an independent Medicare agent; they are compensated by the insurance companies if they assist you with your enrollment.
What happens to my Medicare coverage if I move to a U.S. territory like Guam or the Virgin Islands?
Answer: Your Medicare coverage remains active if your move to a U.S. territory like Guam or the Virgin Islands, as long as you continue paying your monthly Medicare premium. However, it is recommended to enroll in a Medicare Advantage plan (if available) or Medicare Supplement and Prescription Drug plan to help minimize your out of pocket cost for medical, hospital, and medications.
