There is a week each October along the Lincoln Avenue corridor when the mowers come off the trailers and the plows go on, sometimes on the same day. OnePRO Services lives on both sides of that switch. Through the green months it is mowing, trimming, edging and seasonal cleanups; through the cold ones it is plowing driveways and lots, shoveling walks and steps, and treating ice before it can set. Parker's weather never hands over a clean transition — it will drop eight inches in May and go sixty degrees in January — so the trucks stay ready either way. A property looked after all year never has to be rescued.
