Find locum tenens work that pays more and fits your life. Most physicians pick a staffing company more or less at random, hand over their details and hope for the best. Register with a few more and you're filling in the same forms again, then fielding calls you never asked for. It shouldn't be this hard. Messly works the other way round. You build one profile saying what you want. Hand-picked staffing companies pitch you real assignments, with the rate shown upfront. You choose who to talk to. HOW IT WORKS 1. Tell us what you want Your specialty, the states you're licensed in, IMLC, availability, schedule, minimum rate and how far you'll travel. It takes a few minutes, and you stay anonymous: recruiters only see your first name. 2. Get pitched real assignments Recruiters send matched assignments straight to your Messly inbox, with the rate, location and schedule upfront. No vague promises of work that never materializes. 3. Choose who you talk to See who each recruiter is and which staffing company they work for before you reply. When you like an assignment, book a call at a time that suits you. Your contact details are only shared with the companies you choose. 4. Start working The staffing company you pick handles credentialing and gets you started, as normal. There's no obligation at any point. WHY PHYSICIANS USE MESSLY The best assignments: access to a hand-picked group of the best locum tenens staffing companies, in one place Rates upfront: see the pay on every assignment before you engage No spam: you're anonymous until you choose to share your details, so no unsolicited calls, texts or emails You're in control: turn your profile off any time and nobody can contact you. Turn it back on in one tap Everything in one app: assignments, messages and calls, on your phone or computer.
