"We met Gizelle at an Open House with the mindset of leasing a home. She successfully had us pre-approved to buy our beautiful new home. She found a home that met our criteria and are so happy to finally have a home within Newport Beach that we can call our own. Gizelle’s dedication to finding exactly what we were looking for made the experience most memorable. We are so grateful for being introduced to Gizelle."

"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."

  -~SP Dale, Client

"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."

  -~Bishnu Dev, Client

"Gizelle was a pleasure to work with! She worked hard to get us the best price possible. When we listed with her, there were several competitive homes for sale in our neighborhood, and Gizelle was still able to secure two full price offers for our house in under 30 days. She excels at negotiation and keeps on top of every detail. We would definitely recommend her!"
