"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."

"My wife and I purchased our Balboa Peninsula home from Gizelle before we sold our family home outside of the area. When our local realtor was unable to sell our home we asked Gizelle to take over the listing. She had our home professionally staged and within the first week it was placed back onto the market she obtained a full price offer from a well-qualified buyer."
