As many of you have already heard I have accepted a position with Industry renowned IPexpert. I have had many good years working for Ascolta training and I thank them for all that they have supported me in over the years. They are some of the finest people I have ever met.
I will be finishing up my teaching schedule over the next few weeks at Ascolta but will be more active in the Online Study List for Security and R&S, as well as here on the blog.
As I look forward into 2010 I am excited to see the wonderful changes that will come about. I believe that 2010 is really going to rock.
Stay tuned for posts here related to my new task…CCIE R&S and CCIE Voice.
