Say About Us
"I confidently recommend Deron as an excellent business English coach. His expertise greatly supported me in preparing for crucial negotiations with international partners. His tailored approach, blending language proficiency with business understanding, was instrumental in refining my presentation skills and discussing complex matters confidently.
Deron creates a supportive learning environment, fostering progress and boosting confidence effectively."
Tiia Bister

"During our coaching online sessions, we studied different sources of impactful communication and worked on written messaging to support OuluHealth’s mission. We analysed the texts I produced and discussed the ways to make them even more effective. To me, these sessions served as a platform to find inspiration and work on my new writing techniques. The sessions also helped me to pick up any recurring mistakes, especially those that may affect the message or the image of OuluHealth."

“With the help of Deron’s 1-on-1 lessons I was able to build my confidence in speaking English and fulfill my dream of an international career. Deron is skillful in gently guiding and giving feedback to boost confidence in speaking and writing English both in professional (e.g. job interviews) and private settings (e.g. conversations in English about hot topics of the day). I can warmly recommend working with Deron to boost your English skills!"
