Yes I have! None of the local big lawn service-providers (in this area) offer an organic program. And the smaller folks don't understand organic.
The Penn State turf folks have been on-site and did soil testing. Nothing too out of kilter.
FYI: The consensus from Penn State was my pH was too high. With the addtion of the injector and me testing weekly... Didn't seem to correct the problem.
