Wound care in Los Angeles.

Hi, I took NCLEXPN on 4/23, got the good pop up and now im waiting for the official results in the mail. Im REALLY interested in wound care, i currently work in urgent care as a medical assistant, we do some there I had 1 stage 3 it was amazing to watch it heal, but I'd really like to be certified in it, I loved doing it during my clinicals. Does anyone know where to go in or around LA for certification?
