Keller Williams Realty began in 1983 when Gary Keller and Joe Williams created a single real estate office in Austin, Texas. What started as a local firm quickly grew into an international franchise system. The company expanded through a network of market centers that operate semi-autonomously while benefiting from centralized training programs. Keller Williams offers multiple service divisions including residential sales, commercial brokerage, and luxury properties. Their business model emphasizes agent development through profit-sharing incentives and technology platforms.
