concierge healthcare

Over the past couple of years, I've noticed my premiums go up and coverage go down.  A colleague mentioned an available option, "concierge healthcare".  Anyone know much about this type of healthcare?  I believe that this coming year, I might opt out of getting any type of coverage for my self and possibly my family.  The premiums are outrages and I need to pay a very high deductible before I still need to pay 10-20% of the bills after I meet my high deductible.  

This is completely insane.  Not sure if I need to blame this on the "Obamanator".  I've always been a democrat and this is one major issue I have with this new president.  I live in Southern California in case anyone has any ideas of coverage.
