"Gizelle Sieber represented my wife and I in the purchase of our condo in Dana Point, Orange County. We are residents of Singapore and hadn't purchased a property before in the United States. Gizelle familiarized us with the process, was quick to respond to our queries, and diligent in representing us in negotiations with the seller. We would highly recommend Gizelle to anyone looking to buy or sell a home in Orange County."

"After searching for two years to find the perfect home for my family with 10 different realtors, Gizelle located our back bay view dream home within 3 weeks of working with her. She made the home buying experience easy and painless, assisting with all aspects of the transaction even with the actual move itself. We definitely recommend Gizelle to all buyers."

"Excellence is what I would describe about Gizelle! She is so thoughtful, responsive and caters to all your real estate needs. I was looking for a house for two years and had several agents with no success. Then I meet Gizelle and I get my dream home within a month! I strongly recommend her!"

  -~Uthara Mohan, Client

"I gave Gizelle a 60-day time limit to sell my home. Much to my surprise she rose to the occasion finding a well-qualified buyer within 40 days. Every aspect of the transaction went smoothly. I would highly recommend her when considering selling your home."
