As Director of Strategic Marketing & Due Diligence, she oversees how the team’s listings are branded, marketed, and discovered by qualified buyers locally and globally. Weber has worked alongside Hillary Ryan since 2019, helping shape the team’s marketing strategy, brand presence, and client experience.
Her work sits at the intersection of data, design, and storytelling. Weber combines market analytics, advanced digital advertising, and creative direction to craft compelling narratives that elevate homes beyond traditional listings. From vineyard estates and legacy ranches to architecturally significant properties, she focuses on highlighting the provenance, design pedigree, and lifestyle experiences that resonate with today’s luxury buyer. She also collaborates with the global PR team at Sotheby’s International Realty to position notable properties for potential coverage in leading media outlets worldwide.

She manages disclosure preparation and has a strong working knowledge of California disclosure requirements, helping ensure properties are thoughtfully prepared and presented with clarity and transparency.
Prior to joining the Hillary Ryan Group, Weber served as Regional Marketing Advisor for Compass (formerly Pacific Union International) across Napa and Sonoma counties, where she advised more than 150 real estate professionals on marketing strategy and digital advertising.

In that role, she developed and managed targeted campaigns across Google Display Network, Google Keyword Search Ads, YouTube Ads, and Meta’s Facebook and Instagram ecosystems, building expertise in audience targeting, campaign analytics, and digital brand positioning.
Today, Weber applies that expertise to create integrated marketing strategies for luxury properties, combining photography, video, social media storytelling, targeted digital campaigns, and emerging technologies to connect exceptional homes with discerning buyers across key feeder markets including Silicon Valley and the San Francisco Bay Area.
