• How do I Choose an Urgent Care Location?

  • While there are a number of urgent care centers in the Inland Empire, it is important to consider which urgent care location is best for your needs. You could choose to “find an urgent care near me” or an urgent care for specific needs, for example, you may want an urgent care with lab or X-ray services on site.

    For example, if you live in the Etiwanda neighborhood within Rancho Cucamonga, our urgent care center located on Milliken Avenue in Rancho Cucamonga is closest.

    Alternatively, you can choose our urgent care located in Fontana, which is a bit further away but may offer an earlier appointment. You can decide which urgent care is best for your needs.
