Keith Jimenez, RPLS, has been researching and surveying the state of Texas since 1968, starting as a rodman working for his father - also an RPLS - at the age of 14, and acquiring his first license in 1985.
It is difficult to find an area in Texas with which Jimenez doesn't have at least some familiarity. Jimenez has surveyed or supervised thousands of surveys in countries all over Texas, from Beaumont to El Paso, from the Rio Grand Valley to the Hill Country. In addition, his surveys are used by the San Antonio District of TxDOT as a standard format for professional surveys.
