I don't know a doctor in Kansas, you would have to check realself and yelp reviews and call for treatments. This is not a common area we are asked for acne scar specialists nor has anyone mentioned anyhting.
Erbium will do Nothing for icepicks, ... the treatment of choice is TCA Cross (many sessions are needed to raise the scar bed. Some of your boxcars this will also work on if they have a defined border.
Some of the spots need subcision first to release them (box car pits).
RF microneedling works well on boxcars that do not work with TCA Cross. Dr's and med spa's will have this around you like Infini.
I would also do some TCA spot peels to the cheeks once you raise up the icepicks with cross to even things out. We have a guide to TCA Cross and TCA peels, top of the scar solutions sub, first post FAQ. Goto TCA section, click link for post and read the first page.
For what it is worth, I think your scarring is minor and I wouldn't worry too much about them. I wish you all the best for any future treatment.
