A little bit about me...

Jillian Cardona has spent most of her life in the Bay Area, primarily in Castro Valley, where she has also raised her family. Her journey into real estate is unique. While she has prior experience working in both the insurance industry and low-income housing, she stumbled into real estate while looking for part-time work when her kids were young. She started as an assistant to a husband-and-wife team, Jon & Leslie Foster, booking showings and managing their social media. Shortly thereafter, they developed a team, built a brand, and the rest is history. Our team is now 60+ agents strong spanning the entire Bay Area and Central Valley. Over time, Jillian assumed several roles within the Jon & Leslie Foster Real Estate Group, including Administrative Assistant, Marketing Manager, Listing Coordinator, and Director of Operations. In 2021, during the Covid Real Estate Boom, she earned her Realtor license. Today, Jillian is the Sales Manager at the Jon & Leslie Foster Real Estate Group. While her passion lies in coaching agents to grow their businesses and improve systems, she also finds joy in helping buyers and sellers achieve their real estate goals. 

*Fun Fact - Jillian is a repeat panelist since 2024 to speak in front of Zillow's entire executive tech team to help them build, enhance and improve their client facing platforms.
