I took ACLS with Sam. Great teacher but kept us for 10 hrs to finish the class in one day instead of two. He’s very knowledgeable and helpful. The classroom was extremely cold all day. When I asked if the AC could be turned up, the response I got was that the girl in the office with the door closed, gets too hot. There were 5 of us and only one of her !! Who’s more important? And speaking of the staff, the office help was rude when I drove to Lathrop from Modesto to get a new manual. She acted like she didn’t want to be bothered. I love this company and have used them several times for all my certifications, they just need to make some minor adjustments
