Yeah, that's good enough compensation to invest your time a bit - or a lot - in the marketing... you are paid well enough to be more productive, esp if you get DME.
There are way too many DPMs with "MSG job" where they get some dinky base and % and work hard growing it when they have no good reason to. With those setups, you are just making other ppl rich.
You will just be somewhat hosed if they hire another DPM as soon as you hit 25-30+ pts/day and knock your volume back. Who knows what will happen, though. I would proceed as if it won't happen (or you'd get a good say if/when).
I would think it'd be worth it to get YOUR name out to PCPs and area docs, though... for sure. They should pay for the marketing materials, gifts for PCPs, etc. The hospital marketing ppl or office managers should help you with PCP and dept intros also as you will bring them MRI, surg, etc. GL
