Separating the Truth from Lies


Need a polygraph test administered in Los Angeles or one of the neighboring communities? A polygraph, popularly referred to as a lie detector, measures and records several physiological indices such as blood pressure, pulse, respiration, and skin conductivity while a person is asked and answers a series of questions. The belief underpinning the use of the polygraph is that deceptive answers will produce physiological responses that can be differentiated from those associated with non-deceptive answers.  We now partner with over ten police agencies in the Southern California area to conduct their polygraph investigations.

Family Issues and Estate Security

While not admissible in court, a lie detector test can prove useful when it comes to getting to the bottom of family issues and acquiring estate security. The science behind polygraph testing is improving and some find it helpful to rely on the evidence during their decision-making process. Today’s families are remarkably diverse and the diversity affects the way families interact when confronted with estate planning. Too often, people pass away without a complete will or estate plan, leaving their loved ones in a state of uncertainty. Don’t allow your valuable assets and net worth to become a cause of anxiety. Contact Joe Mar to learn about the value of polygraph testing when considering estate security for your family.
