I am retiring in a few weeks. Dan has been very supportive and helpful with giving me advice on the different plans available for a supplemental plan. Along with logging into the website for enrolling into a drug plan. Making sure I can continue going to city of Hope and that all my medication will be available in the plan I elect. Thank you

Dan Peterka was super helpful with all things Medicare and also helped quickly and efficiently add Part G - supplement and provided info for Part D. Don’t even waste your time with others. Dan is a great first and last stop. Highly recommend. True professional.

Dan came highly recommended to us by one of our friends that used him to set up her Medicare benefits. He is so patient and thorough in signing us up for Medicare. He answered all our questions and made the Medicare process so easy. Would highly recommend him!

Diana Ngo is outstanding! She is extremely knowledgeable about provider groups in Orange County and which insurance plans they accept. With UCI Health contracts constantly changing, Diana stays on top of the updates every year and makes sure I remain on a plan that gives me continued access to my doctors at UCI Health. I couldn't recommend her more highly!
