Our Instructors

Meet AccentsOff’s instructors, the team that will guide you in speaking more clearly and confidently. We are all passionate about helping our clients speak clearly and feel more confident about their communication skills.

Our 1:1 accent training program is designed to have you speaking with an improved American accent. Our clients experience greater success at work and in their social lives because they are being heard and understood. And our instructors are all U.S.-based and speak Standard American English.

Our Team of Accent Reduction Instructors

We are a team of certified speech-language pathologists and senior-level accent specialists. Each AccentsOff instructor holds a Masters-level academic degree and has completed a rigorous in-house training program.

Our academic and pedagogical credentials are complemented by our varied backgrounds in the arts (music, acting, writing, languages). This unique combination allows us to teach with sensitively-tuned ears and eyes while encouraging our students to develop mindfulness and good practice habits.

Who you will work with

Your speech training will be guided by a member of our team of Accent Specialists. During your Zoom Discovery Call, you’ll be carefully matched up with one of our staff instructors for a complimentary speech and accent evaluation. You will continue working with your instructor once you start sessions.

Each instructor has the professional and academic background to guide you through a course of intensive study rich in content, with personalized attention and proven results.

Schedule your 15-minute Discovery Call to find out more and get started.
