Meet Our Founder

Hi, I'm Sam Gadd, founder and lead designer of Add & Subtract Design.

For more than 15 years, I've had the privilege of helping families create homes that are beautiful, comfortable, and thoughtfully designed for the way they live. I believe great design isn't about following trends—it's about creating timeless spaces that feel welcoming, functional, and uniquely yours.

At Add & Subtract Design, every project begins with listening. I take the time to understand how you live, what inspires you, and what you want your home to feel like. From there, I guide every detail—from space planning and finishes to furnishings and styling—to create a home that reflects your personality while standing the test of time.

My approach blends classic design with fresh, updated elements, creating interiors that feel elegant without sacrificing comfort. Whether we're refreshing a single room or designing an entire home, my goal is always the same: to create spaces you'll love living in every day.

Thank you for trusting me to be part of your home. It's an honor I never take for granted.

Our home is more beautiful than we ever imagined, and we receive compliments from everyone who visits. We highly recommend Add & Subtract Design!

Such a great experience at the warehouse! We were able to take everything home the same day. Sam was so helpful without being pushy. We'll definitely be back!
