About 20 Mile Urgent Care

We are pleased to be able to serve Parker as both an urgent care as well as a family medicine clinic. We provide a myriad of services to get you well and keep you healthy.

As a family medicine clinic we manage and treat chronic medical conditions, i.e.: diabetes, high blood pressure and elevated cholesterol as well as most other conditions that require close follow up. We also make it a top priority to focus on preventative health care by reviewing with our patients, at each age appropriate visit, the need for things like mammograms, pelvic exams, prostate evaluations, and colonscopy.

We provide services for well child checks, well woman exams, school and sports physicals and can perform simple lab tests in-house or send the labs out when necessary. We have state-of-the-art electronic medical records, which have been shown to improve medical management and decision-making and are able to easily refer patients to specialists for additional evaluations.

As an urgent care clinic, we diagnose and treat acute illnesses and injuries as well as sports injuries. We have a digital x-ray unit on-site and trained staff who know how to take the x-rays as well as interpret them. We can do all kinds of procedures including IV’s, suturing, joint injections and aspirations, ingrown toenail repair, pregnancy tests, biopsies, and many other tests and procedures.

For urgent care visits there is no appointment necessary. For family medicine visits we ask that you make an appointment, being seen the same day in most cases, to serve you better.

You will find our staff and clinic to be very warm and friendly and hope that you will feel comfortable and should the need arise, come back to see us.
