Work with Leonard
About
I help people understand quantum computing and build careers in it, without the hype. I spent seven years working in quantum at Microsoft, first as a Quantum Ambassador and later as a Senior Product Manager on Azure Quantum. Before that, I spent nearly 20 years as a software developer and solution architect. I wrote Essential Mathematics of Quantum Computing (Packt), I’ve created quantum training for Microsoft and IonQ, and I’m an Affiliate Faculty member in Physics and Astronomy at George Mason University. Today I run Essential Quantum Group, an independent quantum consulting firm. I can help you: Map out a realistic path into a quantum career Truly understand the math behind qubits, gates, and algorithms Make sense of what quantum means for your business Working with me is interactive, not a lecture. We’ll work through examples together, I’ll answer your questions as they come up, and I’ll give you practice between sessions so the ideas stick. I’m patient, I’ll meet you where you are, and no question is too basic.

Why do I coach?
I’ve always loved teaching. Some of my favorite moments are when an idea finally clicks for someone, whether it’s my own kids, a new college graduate, or a room full of executives. Quantum computing has a reputation for being impossible to understand, and I don’t think it has to be. Most people just need someone to explain the ideas clearly and show them where to start. I’ve been that person for many colleagues and customers over the years, and I’d love to do the same for you. I also believe quantum computing will only reach its potential if more capable people join the field. Helping you take that step is my small way of helping make it a reality.
