Self-pay COVID Testing Patients May Walk In

Our phone lines can be extremely busy.  If you don't need to be seen today, please use our contact page to get your question answered.  We have someone that monitors the questions from the contact page 7 days a week and you will get an answer extremely fast.

You may come as a walk-in if you are testing for COVID as long as you self pay.  We take COVID testing walk-in patients from 7am until 4:30pm, only if you are paying for the test yourself.  We close early Sunday, so last walk-in will be at 2:30pm, COVID testing only.

If you are walking in for anything else like seeing a doctor, call the clinic first to see if we can take you.

New medicaid patients are welcome.
