About Nathalie

People would be surprised to know that as a child, I was raised to be shy and was socially awkward at school. People know me now as outgoing and friendly. Yet, as a kid, I didn't know how to express my voice. I know what it’s like to feel fear and I know what it’s like to persevere. 

That shift started ASERTIV Public Speaking 🌳. As a public speaking coach, preacher, and keynote speaker, I help leaders like ourselves, own our voice. As followers of Christ, created in His image, He has already given us all we need to own our voices. I just cultivate it. 

Having spoken to audiences from France to Florida, I’ve preached at churches across the Northeast, am a former English teacher and literacy coach, so you know learning effectiveness is key, was recently named Top 15 Coach in Boston 2024 by Influence Digest Media and the South Shore Home Life and Style Magazine featured me in their Empowering Women Fall 2025 issue. A Florida native, be sure to connect with me on LinkedIn, where I post content on public speaking and owning your voice.
