JNE Polygraph LLC on Adams Avenue in Normal Heights, San Diego, provides polygraph examination services for law enforcement agencies, fire departments, attorneys, and therapists from its office at 2728 Adams Ave in the 92116 ZIP. Founded in 2015 by examiner Shon Thurman, the firm operates by appointment and maintains a second examination office in Burbank, California, extending coverage across San Diego, Los Angeles, and Imperial counties. The law enforcement client roster includes the San Diego State University Police Department, the San Diego College Police Department, the La Mesa Police Department, the Imperial County Sheriff's Office, the El Centro Police Department, and the Coronado Fire Department — agencies that use JNE for pre-employment screening of sworn personnel. Pre-employment polygraph examinations follow a structured protocol that includes pre-test interview, in-test physiological monitoring, and post-test analysis, and the firm conducts child safety seminars for community organizations as a supplemental public-education service. Criminal defense and family law attorneys use polygraph results as an investigative tool during case preparation, and The Law Offices of Michael J. Codner represents the kind of Normal Heights legal practice whose caseload generates the type of evidentiary polygraph requests JNE processes. JNE does not conduct infidelity or personal-relationship testing — the firm limits its examination scope to law enforcement, legal, and clinical referral channels. Therapist-referred examinations serve mental health practitioners who incorporate polygraph data into treatment compliance monitoring, a specialized clinical application distinct from the pre-employment and forensic caseload. The Adams Avenue office sits within the Normal Heights consulting corridor that includes legal and consulting firms, and attorneys across the broader 92116 service area regularly contract polygraph services, and The Saint-Jeans Law Firm is among the Normal Heights legal practices whose defense preparation and internal investigation caseload generates polygraph referrals as part of defense preparation and internal investigations. United States Navy installations in the San Diego region also appear on JNE's client list, reflecting federal-level security clearance polygraph requirements handled through the Adams Avenue office.
