What Martin says about Orhan Ergun CCDE class

I attended Orhan’s April 2016 10 days CCDE Bootcamp.

You can tell Orhan has a great deal of experience, it really comes through when he presents his design case studies and the CCDE Practical scenarios– if you are approaching the end of your CCDE journey this is a good place to stop by and put it all together.

Thanks Orhan for everything.
