Private investigator in San Antonio, Texas
250+ five-star Google reviews
San Antonio is home ground. The corporate office is on Bandera Road in Helotes, minutes from Loop 1604, so Bexar County files do not wait on a distant assignment desk. Military families, a large family-court docket, and a busy civil bar keep the work practical and discreet.
Bexar County has its own rhythm: Joint Base San Antonio moves people on short notice, the River Walk and Southtown mix tourist addresses with long-term rentals, and far-northwest suburbs sit close to our Helotes office. We handle family-law surveillance, locates for witnesses who left a post, process serving in gated northwest neighborhoods, and insurance-defense checks when a claimant’s daily pattern does not match the file.
Counsel in San Antonio often needs a same-week activity check or a hard-to-serve subject on the South Side. We also take criminal-defense fieldwork for Bexar County cases and background work before a hiring or a family placement. Spanish-speaking clients can reach us at the same number. This is J.I.S’s own licensed staff — not a matching list.
