How this market compares

Atascadero against every other city in California on the same measure.

Cities with fewer than 500 businesses in total are left unranked.

What acquirers look at

California’s corporate practice of medicine doctrine restricts lay ownership, so deals are structured as MSO arrangements. Not a first acquisition for an unlicensed buyer.
