they usually offer a base salary (monthly min or daily min) then a % of collection whichever is higher, experience usually translates into speed so most likely the dentist will make more on the % collection.
some DSOs I have been in contact with the base salary yearly is 140-180k for these cities. % collection is around 30% minus 30% lab fee (for fixed and removable prosth).
Texas is good if you go to a less desirable area, I am told somewhere up to 200k minimum salary (El Paso, Corpus Christi, Tyler, etc)
