Living in Chattanooga allows access to the fastest internet in the country, and a very secure video conferencing connection. We have had great success in our teaching online. Certainly, teaching in person allows for a more nuanced approach to teaching, especially with tone quality and projection.
However, VERY productive lessons are possible using video conferencing.
When the weather does not allow for safe travel, or if you live in another state and time zone, "Zoom" lessons are always possible. We also do lesson using FaceTime, Skype, and Google Duo.
