Maryland has no NEMT broker. The state funds local health departments and the Montgomery County Department of Transportation through grants, and they arrange rides as the transportation of last resort.
Rides are scheduled through the local transportation grantee in each jurisdiction, so providers contract with the county program, not a broker.
For the licensing steps, see NEMT licensing by state; for how brokers compare in other states, see the NEMT Broker Report Card. Arrangements change; confirm with the state Medicaid agency before you sign.
