Questions, answered
What areas does Big Sioux Benefits serve?
We serve the Sioux Falls metro and Siouxland — eastern South Dakota, northwest Iowa, and southwest Minnesota. That includes Sioux Falls, Brandon, Harrisburg, and Tea in South Dakota, plus nearby Iowa communities like Sioux Center, Rock Valley, and Orange City, and southwest Minnesota towns like Luverne.
Do Medicare plans differ between South Dakota and Iowa?
Yes. Medicare Advantage and Part D plans are sold by county, so the plans, premiums, and networks available in Sioux Falls (Minnehaha County, SD) differ from those across the border in Sioux County, IA. Because we work both sides of the Big Sioux, we compare the plans we offer in your specific county.
Can you help if I live in a small town not listed here?
Almost certainly. We serve the wider tri-state Siouxland region, not just the larger towns. If you don't see your community listed, contact us — we likely cover it, and we can pull the plan data for your exact ZIP and county.
Do you meet in person or only over the phone?
Both. Many clients prefer a phone or video conversation, but as a local agency we can also meet in person across the Sioux Falls area. Either way, the help is free and there's no pressure — we simply compare your options and answer your questions.
