About Full Spectrum Realty · San Antonio
Full Spectrum Realty is a boutique San Antonio real estate brokerage founded in 2009 by Broker/Owner Tammara Alarcon. The firm offers personalized residential, commercial, and property management services to clients across San Antonio and Austin, Texas. With a team of roughly 20 agents who are described as 'experienced across all types of real estate transactions,' the brokerage focuses on tailored guidance rather than one-size-fits-all transactions. The company is licensed by the Texas Real Estate Commission and operates from an office on Wurzbach Road in north-central San Antonio.
Full Spectrum Realty was founded in 2009 by Tammara Alarcon, who obtained her real estate license in 2005 after earlier careers in restaurant management with Hilton Corporation and Marie Callender's, and as a national trainer for American Light Co. She had been managing her own rental properties since 2001 and parlayed that experience into launching a brokerage that today serves both the San Antonio and Austin markets. The firm describes itself as a 'boutique' operation in which 'you and your property are not just an algorithm'; instead, the team tailors solutions to each client's goals across a lifetime of real estate decisions. Their agent roster visible on the site includes Kenn Brooksbank, Tammara Alarcon, Laurencia Quinlan, Giau Phan, Tammy Greenbauer, Carina Johnson, Lauren Dowlen-Garza, Steve Reyes, Brenda Gonzalez, Christine Mayes, Cesar Chavaria, Genina Mery, Candace McCoy, Terry Todd, RJ Gonzales, Julian Ortiz, Ruben Vasquez, Samantha Jordan, DeAnne Martinez, and Samantha De La Garza. Beyond traditional buying and selling, Full Spectrum operates a dedicated property management arm (Full Spectrum Property Management) handling tenant screening, rent collection, maintenance, and regulatory compliance. According to Zillow, the team has roughly 945 lifetime sales and an average sale price around $336K, with team reviews averaging 4.99 out of 5. The brokerage is multilingual (English, Spanish, Vietnamese) and licensed under Broker/Owner Tammara Alarcon's Texas Real Estate Commission license (#0561134).
