What My Clients Say
💬David erkennt individuellen Verbesserungsbedarf sehr genau und arbeitet zielgerichtet daran. Dabei nutzt er eine gute Mischung aus Übungen zur Verbesserung der Aussprache und Übungen zur Verbesserung der Grammatik und der Rhetorik. Empfehlenswert. – Patrick, German Pension Fund Legal Consultant and Lecturer, Germany ⭐⭐⭐⭐⭐
💬”Das Lernen mit David ist super abwechslungsreich und spannend. Durch seine Fähigkeit die Bereiche zu identifizieren, wo seine Hilfe erforderlich ist, habe ich bisher große Fortschritte machen können. Er vermittelt Sprache leicht und verständlich, achtet dabei aber auch darauf, dass das Gelernte in der passenden Art und Weise angewendet wird. Mit David ist es nicht nur ein Lernen der Grammatik und Vokabeln. Es ist ein allumfassender Sprachkurs, bei dem auch die Art und Weise gelehrt wird, wie man sich bestmöglich mit Sprache ausdrücken kann.” – Melanie, Pharma Chemist and Conference Speaker, Germany ⭐⭐⭐⭐⭐
💬”David est très impliqué. Il nous fait des programmes personnalisés. Il est patient. Il préfère faire étape par étape pour que tout soit parfait au lieu de faire 10 à la fois, mais mal.
