With nearly 30 years of experience in real estate, Theresa deSousa is a trusted and deeply knowledgeable advisor in the Portland metro market. Known for her calm demeanor, attention to detail, and masterful negotiation skills, Theresa has helped hundreds of families find their dream homes and navigate complex transactions with confidence. A certified Master Certified Negotiation Expert (MCNE), she began honing her negotiation talents early—growing up in a family of eight children made it a necessary life skill. Clients consistently describe her as responsive, thorough, and genuinely caring.
Born and raised in Oregon, Theresa’s deep roots in the community and longstanding relationships with other agents give her clients a true edge when it comes to market insights and negotiations. She believes in collaboration over competition, always putting her clients’ goals first and ensuring they feel informed and empowered throughout the process. Her clients return time and again, knowing they have an advocate who brings wisdom, integrity, and a personal touch to every deal.
Outside of real estate, Theresa enjoys digging in the dirt—both in the garden and through home remodels. She owns and manages rental properties, has a passion for flipping homes, and is the proud caretaker of over 70 houseplants. Theresa shares both life and business with her husband and real estate partner, Brian Spear. Together, they stay busy cheering on their 12-year-old daughter at competitive soccer tournaments across the Pacific Northwest.
