  • About Alexandra

    A California native, Alexandra has witnessed first hand how much the Bay Area has grown over the past two decades. She has an intrinsic understanding of the potential of what’s coming in each given area as well as its personality. Her eye for interior decor and garden design has led her to become the ‘go to’ person amongst her friends and family. She brings all of these skills to her job, helping her clients to find their dream home.

    With a successful career in marketing, she has a history of building trusted and lasting relationships as well as a proven track record for attention to detail, clear communication and a project management style of organization. When she’s not out looking at homes to find the perfect fit for her clients, you can find her trying new restaurants, exploring the North Bay and volunteering her time at the Humane Society helping dogs get socialized and ready for adoption.


    "Alex Costello made buying a home a joy! She helped me figure out the area in Petaluma that best suits my needs, she showed me the opportunities within my price range, along with all the potential each home had. She was there to get me through the entire purchasing process, the ups and downs. Without her, I would not have found my new home."
