Thousands of people lined up outside the Los Angeles Memorial Sports Arena this week to get wristbands for admission to a free clinic that will offer medical services for people without health insurance for four days beginning today.

The CareNow/L.A. mobile clinic is intended to provide dental, medical and vision health services to the uninsured and underserved.

The goal this year is to serve about 1,200 people each day. More than 800 doctors, dentists and other medical professionals are volunteering their time and effort, according to CareNow.

The clinics will run from 7 a.m. to 5 p.m. on each of the days through Sunday.

CareNow is a nonprofit organization formed by the local organizers and healthcare professionals who helped produce three previous events that provided free care to thousands of uninsured and underserved people in the region.

The organization will provide follow-up care for those who need it after the event ends.

Last year’s clinic, also at the Sports Arena, treated an estimated 6,000 people. More than 14,000 people were treated two years ago when the Forum in Inglewood was transformed for eight days into a multiservice health facility. The value of the care provided at that clinic was estimated to be $2.8 million.
