Authors
One person researches and writes the cost guides on this site. Site ownership is listed separately below, since publishing a domain and writing its content aren't the same job here.
Jessica Martinez
Jessica writes the arborist and stump-grinding pricing that runs across this site, pulling from association surveys, contractor rate sheets, and reader-reported quotes rather than any single company's rate card. A quote that sounds too clean for how uneven tree removal pricing actually is gets a second look before it makes it into a table here. When a reader points out a number that has drifted from what crews are actually charging, she checks it and moves the range before the next update cycle.
Who runs the site itself
Chris Terry owns this domain and keeps it running day to day: hosting, the calculator's code, and the technical upkeep. Writing the pricing guides isn't part of that role here; the two jobs stay separate on purpose.
