About Guillermo

Guillermo Mairena brings both prior real estate experience and deep community involvement to his role as a REALTOR® in Northwest Arkansas. He began his real estate career in 2005 with ERA Semidey & Associates in Tysons Corner, Virginia, serving families throughout Northern Virginia, Maryland, and the greater Washington, D.C. metropolitan area. During that time, he assisted dozens of Hispanic first-time homebuyers, collaborated with Skyland Mortgage’s loan officers on CMAs and buyer education, and participated in a Spanish-language real estate education program on local radio, helping callers understand the homebuying process. His transaction history included properties across multiple counties in Virginia and Maryland, always focused on serving Hispanic families and guiding them through financing, contracts, and negotiating their first home purchase. After relocating to Arkansas, Guillermo spent several years serving families in Rogers, Springdale, and Siloam Springs through community leadership and support. These experiences allowed him to develop strong relationships, understand the needs of first- and second-generation Hispanic families, and become a trusted resource for guidance on homeownership readiness, financial preparation, and navigating real estate in Northwest Arkansas. Guillermo communicates clearly with Spanish-speaking and bilingual clients, offering patient explanations of contracts, timelines, and financing concepts to make the process accessible and stress-free. His philosophy is simple: “People first, homes second.” He is committed to combining honest guidance with Coldwell Banker’s professional training to provide excellent service to every client. He lives in Rogers with his wife, who has many years of experience in the local banking industry and strong community connections. Together, they enjoy supporting organizations, building relationships, and serving families throughout Northwest Arkansas.

Outside of real estate, Guillermo enjoys spending time with his family, cooking, and connecting with the Hispanic community in Northwest Arkansas. He is a fan of sports—especially baseball, soccer, football, and basketball—and also enjoys playing chess and reading whenever he has time. Guillermo appreciates good food, community gatherings, and the opportunity to build relationships with families from different backgrounds. He and his wife make their home in Rogers, where they enjoy supporting local events and sharing meals with friends and neighbors.
