Some questions

Hello, I am new here. I was wondering if anyone knew where I could get surgical tech certification in the Knoxville area. I was originally thinking about being a CNA and I would really love to work either in an OB area or children's hospital. I am planning on taking the CNA classes here in my area in the fall, but then came across (in a simple search) a job offer for a labor and delivery surgical tech. That is what sparked my interest in that profession. If anyone would like to give me their opinion about either job, I'd appreciate it. If anyone knows where I could go about getting my certification for the surgical tech could you let me know. I would only be able to work part time like weekends or night shift, I don't know if that would influence my decision about the professions.

Thank you,
Shalom
