hang out one's shingle

Start professional business

To hang out one's shingle is to establish a professional practice, typically as a doctor, lawyer, or other practitioner.

The expression references the old custom of displaying a sign—often a wooden shingle—outside one's office to advertise services.

It usually implies going into business independently rather than joining an existing firm.
