Antonia is a GEM in the world of real estate! I thoroughly enjoyed working with her and her team. I was kept in the loop during all stages of the sale and had my questions answered in a timely and courteous manner. Antonia is professional, reliable, honest and highly skilled and it’s clear she loves what she is doing and works very hard at it. She is energetic and super-productive and makes things happen!

Selling a home can be a confusing and difficult venture, but with Antonia and her team we felt at every step that we were in the best hands. 5 stars to Antonia! - Brett and Janis H.

We first met Antonia at several open houses in the Walnut Creek area. We were very impressed with her friendliness, professionalism, brochures and the staging of the properties. When it came time to sell our own home and after meeting with her, we decided to use Antonia and her very experienced team. We did not regret the decision. We could not have been happier with our experience working with Antonia - a true professional! - Raymond and Joanne K.
