Devin Morgan, co-founder and CEO of Reliant Polygraph Services (RPS), is a Baltimore, Maryland, native with more than 18 years of federal government service in deception detection. Additionally, RPS, her polygraph business, aims to transform the polygraph experience by adopting a more approachable methodology and educating communities about the advantages of polygraph tests and the diverse career opportunities available in this field.

“A polygraph (often called a lie detector) is an instrument used to monitor and record physiological responses by measuring respiration, pulse rate, and sweat gland activity while a person answers test questions. These involuntary bodily responses are evaluated because significant physiological changes during the exam have a high propensity to be indicative of deception,” Morgan said. “We’re open 24/7, including holidays, because we have to be available when our clients need us.”

Devin Morgan and other polygraph examiners serve individuals, businesses, attorneys, and government/public agencies in need of polygraph testing through Reliant Polygraph Services. Polygraph education sessions and demonstrations are also provided for academic institutions, community organizations, and corporations.

Shattering the Glass Ceiling

Historically, the polygraph field has been male-dominated. However, more women are entering the profession, helping to diversify the industry. 

“According to Zippia (https://www.zippia.com/polygraph-examiner-jobs/demographics), ‘15.9% of polygraph examiners are women and 84.1% of polygraph examiners are men,’ which highlights that women are still underrepresented in the profession. In terms of race, the field is predominantly ‘White (56.6%), followed by Hispanic or Latino (16.6%), Asian (10.5%), and Black or African American (9.3%).’ RPS has been fortunate to hire three African American female polygraph examiners, each with over 10 years of federal polygraph experience, who are exceptionally skilled and share the RPS vision and mission to provide high-quality exams while educating the public and helping change the narrative of what a polygraph examiner looks like.”

Throughout her career, Morgan has held a Top Secret/Sensitive Compartmented Information security clearance with the Department of Defense. Currently, Morgan serves as the Team Chief in the Freedom of Information Act (FOIA)/Privacy Act (PA) Office, where she oversees case officers responsible for processing requests within the federally mandated time frames and ensuring that responses are legally defensible. 

The Birth of a Polygraph Business

Morgan co-founded Reliant Polygraph Services in 2022 with her husband, Doni Morgan, because there were no polygraph businesses in their area with a dual mission of conducting polygraph exams and educating the general public about polygraph testing. 

“I felt compelled to help change the narrative that polygraph examiners are only ‘old, white men,’ and to show that polygraphs can be an extremely valuable tool during investigations and a rewarding career field,” she said.

Morgan added, “I’ve always had a strong interest in human behavior, credibility, and investigative work, and I was drawn to providing a professional service that helps individuals and organizations find clarity, resolve conflict, and make informed decisions when the truth is in question. The icing on the cake is that I knew I would excel in this business, thanks to my federal training and years of experience, combined with a non-threatening, non-intimidating approach.”

Reasons Why People Are Given Polygraph Exams

Morgan explained that polygraphs are often used to support investigations, guide legal or workplace decisions, and provide peace of mind in personal matters where trust has been damaged or questions remain unanswered. 

“Many clients come to us in crisis, often involving sexual behavior concerns such as infidelity or sexual assault allegations. Other common reasons include theft-related investigations and drug-related matters, especially when an employer, attorney, or family needs reliable information to make an informed decision,” she stated.

Additionally, polygraphs are not used only for government job investigations. Corporate employers may use them as well, although their use in the workplace is more limited and depends on applicable laws and exceptions. 

Morgan noted that polygraph testing is generally considered 80–90% accurate when properly administered. 

Professional Requirements 

To be recognized as a certified polygraph professional, an individual must complete a formal polygraph training program and hands-on instruction at an American Polygraph Association (APA) accredited school. The examiner must complete on-the-job training, conducting exams under supervision and oversight. 

“Some programs may also require an undergraduate degree as part of the eligibility requirements. Licensing is handled on a state-by-state basis, and requirements vary by jurisdiction,” said Morgan.

Morgan’s Professional Viewpoint 

RPS-administered polygraph exams are conducted with the voluntary participation of the examinee. Morgan takes providing polygraph services as an investigative tool very seriously.

 “I view it as a responsibility—not just a job. Most people come to us during stressful, life-changing situations, so I approach every case with professionalism, fairness, and empathy. It’s rewarding to help individuals and organizations find clarity, but it also requires staying neutral, following ethical standards, and treating every examinee with dignity and respect throughout the process,” she added.
