I have been working in this industry for eight and a half years now. I will say that certifications are great and give some comfort. However from past experiences I have found that individuals with the technical aptitude and the want to learn will find a way. I'm proud to say that I'm self taught or have taken an in-service of some sort to learn what I support or what I will be supporting.If you have any questions please fell free to call. I will be more than happy to supply anyone with references. Thank you for your time.
