For many people, finding time to go to a doctor for medical attention and check-ups can be one of the most time consuming responsibilities of yearly routines. Doctor’s appointments are often scheduled months or weeks in advance, which can be frustrating if your schedule changes often or you have responsibilities at home that consume your time, such as work or children.
That is why CCOM Medical Group provides walk-in care and same-day appointments Monday through Friday from 7:30am to 5:00pm.
