I moved out of state and my CNA certification was out dated in California where it originated from. I then took a re-certification class in Louisiana and got a CNA certificate there. I now reside in Greensboro, NC where they require my original certification number. I got it in the year 1983-1984 In Southern California from Casa Loma College in Lakeview Terrrace which is now located in Van Nuys California. I would like to know where to find my original certification registry number for California.
