Business English specialist - corporate training & conversation groups (Callan Method). 11 years' experience, Edinburgh Economics degree, international company background. Group discounts available.

Best English teacher I've ever had, hands down! I'd been stuck at intermediate level for years, too scared to actually speak. Roberta made me feel so at ease from the first lesson - she's genuinely friendly and creates this relaxed atmosphere where you forget to be nervous. The Callan Method conversation classes completely changed my speaking ability. After just four months, I traveled to London and had full conversations with locals without panic. If you've been studying English forever but still can't speak confidently because you're too anxious, Roberta is exactly who you need. She'll have you chatting comfortably before you know it!

I worked with Roberta for six months to prepare for client presentations in English, and the improvement was remarkable. As a marketing manager at a tech company, I needed to sound confident and professional during video calls with international partners. Roberta's lessons were always focused on practical scenarios - we practiced real presentations, worked on my pronunciation of technical terms, and refined my email writing. What impressed me most was how she created such a comfortable environment that I stopped being afraid of making mistakes. Within three months, I was leading quarterly reviews in English without nervousness. Highly recommend for any professional who needs results, not just grammar lessons.
