Who I work with

I work with established interior designers who are running full design firms, managing teams, leading high-end client projects, and quietly missing the part of design that feels creative, tactile, and expressive.


IF THAT’S YOU, YOU’RE NOT ALONE

Many designers I work with feel the same pull back to the hand-drawn side of their craft.

I created the Bertrand Williams School of Design Visualization specifically for designers who want visuals that feel personal and unmistakably their own.

our purpose

To bring sketching back, and make it a mark of the future and an indispensable element in every designer’s toolkit

our vison

To become the leading institution for the art of design visualization across all disciplines of design, setting new standards for the industry, and turning BW into a mark of honor.

our misson

To offer exceptional quality classes, material, and tools that enable and empower designers to form, visualize and communicate their ideas and projects with intention, clarity and precision.

What I do for interior DESIGNERS

I support designers in two ways:

01. CUSTOM HAND - RENDERED ARCHITECTURAL ILLUSTRATIONS

For the rooms you don’t show in 3D, the concepts you want clients to instantly understand, or the presentations that need a more editorial, high-end feel, I create fully hand-drawn architectural illustrations.
All by hand. No software. Nothing generic.

02. HAND RENDERING INSTRUCTION FOR BUSY DESIGNERS

If you’ve always wanted to sketch or render confidently but don’t have hours to learn, I teach a clear, simple process designed for real design schedules.
No overwhelm.
No overcomplication.
Just the skills that help you communicate your ideas visually.

VIEW OUR CLASSES

Your drawings should look clean, intentional, and beautifully controlled, even the first time you put marker to paper. That’s why I teach marker strokes and rendering techniques you won’t find anywhere else, methods that make your work look impeccable from the very beginning.

My Approach & How I Teach

Together we will

Experience hand rendering in a way that’s comprehensible, fast, and instantly usable. You’ll understand what you’re looking at, what to practice, and how to apply the skill immediately…even with a full project load and a busy firm to run.

Your design work deserves visuals that rise to the level of your talent.
Your process should feel creative again.
And the way you present your ideas should feel unmistakably your own.

Whether you want custom illustrations created for your projects…or you're ready to develop a signature hand-rendered style of your own…


I’m here to make the path simple, calm, and doable.

When you’re ready to reconnect with the creative part of your work, and present visuals that set you apart…

I’d love to partner with you.
