Patient Reviews
Nov 26, 2022
My husband came down with Covid and Dr Singer was on call. He suggested my husband get an anti viral infusion at a hospital. He was sicker than we realized and he was admitted to the hospital for almost a week. If it wasn't for that suggestion my husband could have died. I thanked him via a non urgent message on the portal at 11 pm. He answered within a half hour with a kind message! Now that's a doctor!
