Healthcare advice

Hi I’m in need of some advice about healthcare. My dad owns his own business so my family is not currently enrolled in any healthcare. This has started to become a bit problematic for us so we’re hoping to enroll the family. Which companies/plans are best?

EDIT: Okay I realize now my request was vague. Where should we start in looking for a plan? We’d need a plan that could cover expenses for biyearly mammograms and HTN medications for example. If someone has a plan they pay for themselves and they like please let me know.
