Prior to becoming a Real Estate Broker, I personally went through the experience of being a homebuyer and seller in the competitive Seattle market. I took to heart what an intense and even scary situation it could be without the right professional on your side to guide you through the process. My goal is to alleviate that stress for my clients, by providing top tier customer service, using the best real estate technology platform available and the backing of an entire team to support my clients. I am a proud third-generation Seattleite and UW grad. My experience in sales and marketing of properties is unmatched and my goal is to make your buying and selling experience as seamless as it can be!

From start to finish, the process was smooth and stress-free thanks to her steady communication and attention to detail. Through Redfin’s Concierge service, she connected me with the right contractors
Anand N Closed Sep '25 for $1,000,000
The market wasn’t easy and there were times we felt pretty discouraged, but she never disappeared, and always made us feel like she was in it with us. It never felt like “just another sale” to her.

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.
