Need advice for starting out

I'm probably on the wrong message board, so please forgive me. I have been working as a receptionist at a local nursing home/AL center, and I love it. They offer CNA classes, and I'm very interested in taking it. I just don't know if that's the right step to take, or if I would have other options. I have a BS in business, with only 3 science classes taken for that degree. Is there another option for me, where I could work in the geriatric health care field? Any information would be very much appreciated. I live in CT
