Isaac Danso-Gyan enjoys simplifying complex tech into something anyone can understand. With more than a decade of experience working on enterprise networks from routers and switches to advanced firewalls, he has helped banks, schools, and global companies keep their systems running smoothly. Over the years, he has guided hundreds of students into networking, many of whom have gone on to earn top industry certifications and rewarding IT jobs.

As the founder of the Network Professional Training Center (NPTC), Isaac teaches by showing and not just telling. He guides learners through clear steps, real-life examples, and hands-on labs that make everything click. He has written To Be a Network Engineer and How To Become A Cisco Firewall Engineer to bring that same classroom experience to readers everywhere. For Isaac, teaching is more than a job. It is a way to help people grow, gain confidence, and build solid futures in a fast-moving industry.
