We'll let you know who your professional is as soon as we've made a match. This could happen anywhere from a few days beforehand, to just a few hours, depending on your city.
If you want to check, visit the Bookings page in the Handy app, select the booking in question, and check if there's a name next to the "Professional" field. If not, don't fret; we'll make sure a pro arrives on time.
