I took Doug’s CCNA class when he was teaching at Johnson County Community College. He is an excellent instructor, and really cares about his students. He gave me the tools, along with the little push that I needed, to pass my CCNA Routing and Switch exam. He will do everything in his power to ensure that you pass your exam. He is very knowledgeable, and I would highly recommend him, if you are wanting to learn Cisco Routing and Switching!
