Meet Aaron Plascencia — The Leader Behind Alliance Land Surveyors
With over 15 years in the land surveying industry and two Registered Professional Land Surveyors (RPLS) on staff, Aaron and the Alliance team deliver survey-grade precision to clients across San Antonio and Bexar County.
Built on Precision, Driven by Service
Alliance Land Surveyors was founded on a simple idea: property owners in San Antonio deserve accurate surveys, transparent pricing, and a team that actually picks up the phone.
Aaron Plascencia has spent more than 15 years in the land surveying industry, building deep expertise in the field before founding Alliance Land Surveyors in San Antonio. From managing survey projects and coordinating field crews to navigating Bexar County plat records and city permitting requirements, Aaron's hands-on background drives how the company operates every day.
As CEO and founder, Aaron oversees business operations, client relationships, and quality control. Alliance employs two Registered Professional Land Surveyors (RPLS) — licensed by the Texas Board of Professional Engineers and Land Surveyors — who seal every survey the firm produces. This means clients get the responsiveness and personal attention of an owner-operated company backed by the technical authority of licensed professionals.
"I built Alliance around one idea: if you answer the phone, show up when you say you will, and deliver an accurate survey at a fair price, clients will keep coming back. Our two RPLSs and our field crews make that happen every day."
Alliance Land Surveyors holds Firm License #10194244 issued by the Texas Board of Professional Engineers and Land Surveyors. Every survey produced by the firm is reviewed and sealed by one of Alliance's two in-house Registered Professional Land Surveyors, ensuring every document meets the standards required by title companies, lenders, courts, and local permitting authorities. The firm also maintains BBB Accreditation with an A+ rating.
What sets Alliance apart from larger surveying firms in the San Antonio market? Responsiveness. Aaron and his team have built a reputation for fast turnaround times, clear communication throughout the process, and fair pricing without hidden fees. Clients regularly mention next-day field crew availability and having survey documents delivered within days — not weeks.
Today, Alliance Land Surveyors employs a full team including two Registered Professional Land Surveyors (RPLS), experienced survey field crews, CAD drafters, and project coordinators — all operating from the firm's office at 18410 U.S. Hwy 281 N #109, San Antonio, TX 78259. The team serves homeowners, homebuyers, title companies, real estate agents, developers, builders, and attorneys throughout San Antonio and Bexar County.
