The MSK Design Build Team
Scott Westby

Scott Westby, President, Owner

After graduating with a JD and MBA from the University of Oregon, Scott worked in the field of law, first in corporate law and then in construction law. But he always loved to build. “My dad is a builder/remodeler, and my brother also has a construction company back in North Dakota. I started helping my dad when I was old enough to pick up nails, and I worked in numerous areas of residential and commercial construction. After years of practicing law, I decided to get back to building, and opened MSK Design Build in 2001.”

Scott has a great eye for architectural detail, a talent for overcoming design challenges, and provides innovative design solutions where others have not. He has a vision for what can be done in a home and the ability to bring that vision to reality.  Scott and the team have won  21 awards for design and contracting since 2006. When he’s not working, Scott enjoys reading, golf, skiing, and biking with his wife Kat. They enjoy entertaining at their home in the Oakland Hills.

We love what we do, and it shows in our work.”
