Native English speaker with PhD can improve your English speaking skills from basic to technical

I am an English native who is able to give English lessons to all levels from the ages of 3 to 83, professional, leisure or for academia. I have 6+ years experience of tutoring in Chemistry at Masters and PhD level in the UK and I have given private one-to-one English lessons since moving to France in 2016. I treat each student individually by talking for 10-15 minutes beforehand to understand the level or English and also how to student likes to learn. We don't all learn in the same manner, therefore I am happy to adapt to suit their needs, using a variety of resources. I work significantly on the oral side as I find this is where people are the least confident. I hope my calm and friendly manner will put anyone at ease and builds trust. I like to give homework and little challenges as this creates a great rapport between student and tutor. It also permits me to evaluate the progression between sessions. I'm not looking for perfection, but a willingness to learn and improve.
