While they're not a SMALL democratic group, I certainly wouldn't consider them a CMG. They're a large democratic group.
From their website:
CEP America is a democratic physician partnership, with ownership of the Partnership and our subsidiaries distributed equitably among the practicing physicians. There are no outside owners or investors, so all income from the practice - after operational expenses and billing and malpractice costs - is fully returned to our physicians.
This Partnership structure provides an inherent incentive to meet the expectations of our client hospitals and patients. The Partnership has no debt, and all capital needs for business purposes are self-financed. Our practice management company is owned by the Partnership, which, in turn, is owned by all physician Partners. CEP America has no physician employees, as all physicians are Partners from the day they work their first clinical shift.

That's not a CMG, that's a large DG.
We use the same 401(k) as them (which is a good one) so I have been to meetings with them before. I have a good friend who recently changed from their group to ours. The main problem with CEP is they're mostly in California, which is financially speaking a toxic wasteland for emergency physicians. High cost of living, high taxes, crappy reimbursement, poor payor mix, lots of self-pay illegals, crappy MediCAL etc. I think CEP is doing pretty darn well against that background.
