About Your Polygraph Examiner

I am Sam Angulo, the sole owner of DF Polygraph. I worked for 30 years with the Los Angeles County Sheriff's Department, retiring in January of 2002. I worked for 21 of those years conducting felony investigations, during which time I conducted thousands of polygraph examinations for crimes ranging from fraud to murder.

I received formal polygraph training in 1985 in Arcadia, California, and I have attended yearly training since then to upgrade to the newest polygraph technologies.

I am a member of 2 polygraph associations.
