The Team

Liana DeMartini White founded The L Agency after building a career across retail, buying, and wholesale sales within the lifestyle market.

With experience on both the retail and brand side, she brings a well-rounded understanding of product assortment, consumer behavior, and strategic growth. Her background spans specialty retail, surf, resort, and lifestyle markets—giving her a unique perspective on both brand development and retail partnerships.

Through The L Agency, Liana partners with brands to support thoughtful growth strategies while helping retailers, boutiques, resorts, and destination accounts discover curated products aligned with their customers.

Known for her organization, market knowledge, and relationship-driven approach, she focuses on creating meaningful partnerships that drive long-term growth for both brands and retail partners.

Shannon Halberstadt joined The L Agency with a foundation rooted in the industry from the ground up. Growing up surrounded by the world of sales, she developed an early familiarity with the business, from setting up for trade shows to hanging lines, building an instinct for product and process long before it became her career.

Now pursuing a degree in Business Economics at UC Irvine, she brings both academic grounding and real-world perspective to her work with brands and retail partners. Her hands-on experience managing a diverse buyer portfolio reflects the same relationship-driven, detail-oriented approach she's carried since day one.

Through The L Agency, she supports meaningful connections between brands and retailers backed by a genuine passion for the industry she's grown up in.
