Cybersecurity Analyst (CISSP/OSCP) | Technical & Conversational Lessons Hi! I'm Bertil. I speak English and Dutch fluently, English daily with my American wife and at work, Dutch with family and fellow Nederlanders. I work as a Cybersecurity Analyst at a European bank and hold CISSP and OSCP certifications, which lets me offer something a bit different: English lessons for IT and security professionals, alongside general conversation practice in Dutch or English. For IT and cybersecurity professionals, I actually work in the field, so we can use real materials: threat reports, CVE descriptions, incident documentation, and certification exam language. You'll learn technical English the way it's actually used at work, not just textbook definitions. I can help with CISSP, Security+, CEH, and OSCP exam terminology, professional writing, and vocabulary across the security domains. For general learners, we'll focus on everyday conversation, vocabulary, and building confidence to speak more naturally in Dutch or English. I'm patient and adapt to what you need. Some students want structured practice, others prefer free conversation, so tell me your goals and I'll tailor lessons around them. I correct mistakes gently but consistently, the aim is progress without stress. Looking forward to meeting you!

Bertil is an absolutely amazing teacher! Our Dutch conversational classes are the highlight of my week. He is incredibly helpful with a deep knowledge of so many different topics. He is always friendly, well informed and genuinely wise, which makes our classes resemble a meeting between 2 friends having a great, interesting chat. It is a perfect mix of sometimes going really deep into serious topics and other times just having a nice, friendly conversation. I highly recommend his classes to anyone who wants to learn in a truly professional yet friendly atmosphere!

Hij was heel erg aardig en wij spraken de hele tijd in het nederlands over computerveiligheid onderwerpen.

I personally really like talking to Bart! This is almost my 10th chat with him and every time he is helpful and patient. Highly recommend to folks who are A2 level. A1 might struggle a bit because you may not have the vocabulary and/or grammar to express what you want or to understand/hear what is being said.

Bertil is very patient, encouraging, and excellent at correcting mistakes without making you feel self-conscious. Highly recommend! Bertil is heel geduldig, motiverend en erg goed in het geven van feedback op fouten op een prettige en ontspannen manier. Echt een aanrader!
