Sebastian Manjarrez

Sebastian Manjarrez works alongside Jeff Bischofberger at Lee & Associates – Ontario, specializing in office and medical office properties throughout the Inland Empire.

Sebastian brings a technology-driven approach to commercial real estate, leveraging AI-powered research tools alongside industry data platforms and traditional market analysis to evaluate properties, tenant activity, comparable transactions, ownership records, and emerging opportunities.

A significant part of his market knowledge comes directly from the field. Through consistent prospecting and conversations with business owners, tenants, property owners, and other market participants, Sebastian develops firsthand insight into lease expirations, expansion and relocation needs, ownership objectives, and changing conditions within the local office market.

His focus on Ontario, Rancho Cucamonga, Upland, and the surrounding Inland Empire allows him to combine property-level research with direct market intelligence, supporting the team's tenant representation, landlord representation, acquisition, disposition, and business development efforts.

Working alongside Jeff, Sebastian is committed to providing clients with responsive service, thorough market research, and a modern, data-driven approach to commercial real estate.
