Dr. Nelson is engaged in full-time clinical practice at UCI Beckman Laser Institute and Medical Clinic on the campus on UC Irvine, serving patients with pediatric port wine stain birthmarks, hemangiomas and other vascular malformations and skin disorders. But like many businesses in the state, his clinic was temporarily closed. "Since we're an outpatient surgical clinic, we were closed for about six weeks," he says. "We've since reopened on May 11. The clinic is up and functioning, but it's a very different world now. We're all wearing masks, face shields and personal protective equipment that we didn't really need previously."
