I am considering doing the STNA course. I live in Middletown. Can anyone please give me any information on classes in or around the Hamilton area? Also I am 40 years old, is this too old to try to start this? Also and my biggest scare is my background. I don't have any felonies, but do have quite a few misdemeanors. How can I find out if I would be able to take the course. Thank you in advance for any and all information!
