This place is what it is - it is a hospital, physical therapy, drug testing, mask testing, work specific testing, worker's compensation review, urgent care, and a doctor's office.
Bottom line, you might come and be seen right away OR you might wait 3 hours to do a 3 minute drug test. Or maybe they will bring someone in out of a ambulance. Never know.
Make sure you bring a fully charged phone to deal with the wait.
