Laura Marshallsay, M.A


I’ve led a varied and somewhat crazy life. But what a life it’s been!

I started my professional life as a soldier/administrator in the U.S. Army, and over the years I have been a secretary, mom, and even a tour guide. Then, when I was in my forties, I headed to university to study my two passions: history and writing. 

A few years ago, we moved to  Frankfurt, Germany, and now I help people around the world – both native and non-native speakers – improve their written and spoken English.
