Sucess Stories

Michael Zsiga

I passed the #CCDE today! I used a lot of resources to be successful but I need to call out one specifically. Thanks Orhan Ergun for always being available at all hours to answer every question, to discuss every technology, and to work through my personality “issues” that I had throughout this process!! For all my friends venturing down the CCDE path Orhan is a great resource and friend to have!

Jason Gooley

Orhan’s ability to cover the vast topics required for CCDE is tremendous. He is not only very technical, he is also an amazing teacher.

Daniel Lardeux

I passed the CCDE Practical exam and Orhan’s CCDE course was very important contributor to my success. I attended the CCDE course of Orhan Ergun in July and it was exactly what I needed, Orhan is taking the pain to break down the different technologies.

Roy Lexmond

After I attended Orhan Ergun’s CCDE course I passed the CCDE practical exam.I really enjoyed the course a lot.

Before I signed up I didn’t know what to expect but it’s for sure a great design course and preparation for the CCDE exam. Mainly because of the interaction with Orhan who is really an expert in explaining all the different technologies and making perfect designs out of them.

Hashiru Aminu

I passed the most respectful Cisco exam CCDE on August 2016. I became first Nigerian CCDE and Orhan Ergun’s CCDE Bootcamp was the most important resource in my success.If you want to nail down CCDE, you need to think as a designer. You need to change your mindset and understand all the technologies in the CCDE Blueprint.Orhan’s resources cannot even comparable with the any CCDE Training provider in the industry.I would highly recommend the Orhan’s CCDE Bootcamp for anyone who want to pass CCDE exams and understand the real life network design

Nicholas Russo

I signed up for Orhan’s CCDE training. This training is very technically detailed and the use-cases, quizzes, scenarios, and mind maps are all great resources in the overall training program. Orhan teaches his students to think like a network designer by applying technology to meet business requirements and design specifications.

Nicholas Russo

Anders C. Petersen

Orhan is forcing you to take off the implementation hat that most of us have been wearing for many years, instead he is providing a new fancy design hat, which makes you see and deal with the issues presented. At the beginning of this CCDE course you many times are sitting thinking ‘I could solve this issue with some fancy trick/feature’, all because you keep thinking implementation. However as the course goes on Orhan is helping you to fill your new fancy design hat with all the important information not only for designing, meeting business requirements, but also dealing with the interaction of the protocols. If you’re trying to get your head into a new hat, chasing the CCDE exam, or just wants to get on top with network design, I would go to Orhan today.

Tahir Munir

I passed the CCDE exam on November 17,2016.Orhan’s CCDE Live class and Self Paced training course helped me a lot to pass the both CCDE Written and Practical exams.Design comparison charts and videos will help you a lot in CCDE Practical exam. The quizzes in the self paced CCDE course is excellent resource for the CCDE Written exam.If you are studying for CCDE exam or want to learn network design,I strongly recommend you to take this course.

Felix Nkansah

If you are considering studying for the coveted Cisco CCDE certification, make good use of the Cisco recommended reading list and CiscoLive videos focused on design. But your preparation won’t be complete without a touch of Midas from the master CCDE trainer Orhan Ergun. He is the most complete training provider in the industry – Books, Blogs, Videos, Bootcamps, One-to-one chat, etc.Self Paced Course is a best offline CCDE resource !

Kim Pedersen

I’ve used Orhan’s self-paced CCDE training material. If you are interested in knowing how all the technologies go together in a coherent design i can highly recommend it.I also enjoyed the Quizzes which helped pick out my weak spots in selecting an appropriate design. So if you are serious about either learning more about the design aspects of networking or you are going for the CCDE practical, you should take a hard look at Orhan’s Self-paced Training option.

Concepcion Diaz

The eleven days spent in Orhan bootcamp was invaluable in helping me build confidence and master my design concepts. After a long number of reading books and watch all the Cisco Live design sessions, this class was definitely the advantage I needed to take and pass my CCDE lab. Thanks Orhan for your all supports

Pramod K G

Thanks Orhan for your Instructor Led CCDE Bootcamp. It was very informative for CCDE Written and Lab preparations. Personally we used to discuss designs related to production networks (ISP,DC/Enterprise) & I must say he is technically sound in Network Design. I am impressed with your technology comparision charts when it comes to selection of routing protocols, VPN technology solutions etc.
I strongly recommend Orhan Ergun’s class if you want to pass the CCDE exam and learn network design.

The community of people that Orhan facilitates are both engaging and supportive of the journey to CCDE. Orhan was always quick to answer any email or chat messages that I sent him.

Shiling Ding

Just passed the CCDE Practical exam! I attended Orhan Ergun’s CCDE training program , used Orhan’s Instructor Led and Self-Paced CCDE training and Online CCDE Practical Scenarios during my CCDE journey. Orhan’s CCDE In Depth book is an excellent summary book about almost all topics related to CCDE. Orhan’s practical scenarios are well organized and discussions in his webex are very valuable. Orhan’s also from time to time host webex lectures on different technology topics, I find it’s another revenue to refresh and strength my understanding of different topics. Orhan’s study group is very active, different peers share their experience, discussion and insight on not only the CCDE but also different technologies.

I surely appreciate Orhan’s excellent training materials, constant guidance and demonstrated dedication to help me get CCDE. As always, life is a constant learning experience, CCDE is only one of small steps!

I registered to Orhan’s training in Feb 2017. From that time, I attended Orhan’s training several times. The depth of knowledge which Orhan has is amazing, and how to present such consistent knowledge to the trainees was indeed appealing.
Furthermore, Orhan is not only trainer, he was real mentor to me, He showed me the concept that “Where I’m now, and where I should go”, this is indeed the true leadership !

I passed the CCDE Practical Lab exam on November 17,2016 from supplications of elders and dedication from my Sensei Mr. Orhan Ergun I took different CCDE bootcamps in the past. Orhan has the most depth and expertise. You can discuss with him at an expert level on different technologies and he is focused. Both the bootcamp and his book helped me a lot in achieving the design skills to nail this beast. I would recommend taking his CCDE training to pass CCDE exam and learn the network design

I signed up for Orhan’s CCDE Self paced Course. This course, along with the CCDE In Depth book, helped me for my CCDE Practical as well as Written exams. It pushed me to ask the “WHY” questions and allowed me to grow as a network architect. The use cases, quizz, and compare charts are all great.
