After a successful career in telecommunication and technology, I became a real estate agent in 2003 seeking to pursue my passion for helping people. The technology at Redfin, coupled with the support that I receive from my team gives me the opportunity to really focus on providing excellent service to each of my clients and save them money. As my client, I will be with you through every step of the home buying process. You will never be at the mercy of my schedule. I pledge to you that I will provide you with the support and excellent customer service that you deserve.

The best homes deserve the best agents
Redfin Premier agents are local luxury experts with years of experience buying and selling high-end homes. Only our best agents qualify to become Redfin Premier agents.
When you're ready to buy, your agent will know what it takes to write a winning offer for the most highly sought-after homes. And when it's time to sell, they will know how to price, prepare, and market your home, so it attracts qualified buyers and sells for top dollar.
Plus, keep more of the proceeds from your home sale by paying a 1% listing fee when you buy and sell with us, less than half of what brokerages commonly charge.
Meet Joseph's Team
When you work with Redfin, one agent is responsible for your success, but you really get a whole team. Redfin agents work closely with a team of real estate professionals to ensure every sale closes without a hitch.
