I used Virtual ER yesterday and it worked like a charm, computer to computer. If you have a migraine or a bad cold you can call the ER doctor and he will diagnose you with your web cam. And he can email your prescription to the pharmacy of your choice. I don't have to drag my half dead body to the doctor's office. This is GREAT!

Raymond CampbellLocal Guide · 44 reviews

I have taken my girls here a few time for various issues (broken arm, high fever, allergic reaction) I've always been happy with the care given. The support staff and doctors are great.

Efficient and knowledgeable Doctor! This was a very timely consultation, which is what you need when you have sick kids, in our case it was 2 kids with ear infections.

Cristhell M.Local Guide · 30 reviews

The care at the clinic is wonderful. They have a great team. I arrived in poor health, and the receptionist, the nurse, the radiology technician, and Dr. Quintanilla all attended to me quickly.
