Our INE Instructors

Brian Dennis, #2210 CCIEx5

"For those of you who know Brian Dennis you will know he is a 5xCCIE and a Cisco dynamo."
—Roger Perkin, INE Bootcamp student

With more than 24 years of industry experience, Brian Dennis is undeniably one of the world’s most esteemed CCIE instructors. The wealth of Cisco networking knowledge that Brian brings to INE students is immeasurable, and his commitment to providing the best quality CCIE training is unmatched.

After achieving his Routing & Switching certification in 1996, Brian accumulated four more CCIE certifications in Voice, Security, Service Provider, and ISP Dial. He is now the only 10-Year CCIE who holds five simultaneous CCIE certifications. Brian prides himself on leading INE students through any challenge, all the way to CCIE certification.

Brian McGahan, #8593 CCIEx3, CCDE #2013::13

"Brian McGahan may be the best technical instructor I have ever encountered."
—Matther Heffler, CCIE #36646

At the age of 20, Brian McGahan earned his first CCIE in Routing & Switching and became known as the “youngest engineer in the world.” He continued on to earn CCIE certifications in Security and Service Provider. We’re proud to have such an accomplished and driven instructor on the INE team.

Brian has developed and taught for INE since 2002, setting the bar for CCIE training and helping thousands of engineers obtain their own certifications. When he is not developing new products for INE, Brian McGahan consults with large ISPs and enterprise customers.

Mark Snow, #14073 CCIEx2

" …other than the class consensus that he has really great hair, I’d have to say Mark knows his stuff cold."
—INE Bootcamp student

You might say that Mark Snow began his networking career at the age of 5, when his father, a patented research scientist at AT&T Bell Laboratories, started to share his knowledge with Mark. He has been working with data and voice technology ever since, beginning with Unix System V and basic analog telephony and progressing to large data networking projects and large phone systems in both enterprise and 911 PSAP environments around the world. You’ll see Mark in all of INE’s Voice video courses and live Bootcamps.

Mark Snow is also an accomplished pilot, and when he isn't learning, labing, consulting, or teaching, he can be found jumping out of a perfectly good airplane, hanging off a rock somewhere, skiing out west, or just enjoying a quiet day at the beach with his wife and two wonderful kids, Ryleigh and Judah.
