Brian Karr
Founder · Holz + Stein Development
Holz + Stein Development is led by Brian Karr, whose 20+ years in the construction industry form the foundation of the company's success. Brian founded Holz + Stein on a simple idea: commercial buildings deserve residential-grade craftsmanship, and homes deserve commercial-grade discipline — a rare crossover approach that defines every project the team delivers.
Commercial buildings deserve residential-grade craftsmanship, and homes deserve commercial-grade discipline.
