THE FOUNDER AND CHIEF EXAMINER

    Koa Fung Chew, PPA, PBS, founder and Director of Polygraph Investigative Services, is a retired Superintendent of Police with the Singapore Police Force with more than 48 and 40 years of practical experience in interviewing and polygraph testing respectively. While in active service, he held senior positions, including Chief Polygraph Examiner and Head of the specialist Interrogation Unit in the Ministry of Home Affairs where he dealt with important criminal cases, terrorism, espionage, internal investigations, personnel screening etc.

     A certified polygraph examiner and polygraph instructor, he was the first Singaporean to be trained in the polygraph. He received his polygraph training in 1977 at the American Institute of Polygraph Technology and Forensic Psychophysiology at Michigan, USA and the Israel Polygraph Institute. He had subsequently served as a government polygraph consultant for many years.

    Since 1974 till now, Supt (Ret) Koa has also trained more than a thousand local as well as foreign law enforcement officers in the art of interrogation and interviewing. (See details and list of prominent Government clients).

    Always results-driven, Supt (Ret) Koa has helped government agencies as well as private sector organisations crack many important high profile cases with his interviewing and polygraph skills. He travels overseas frequently to help government agencies, multi-national corporations, top legal firms, millionaires, and ordinary private individuals to solve difficult cases, especially cases involving corporate "insider crimes" like theft, sabotage and corruption.

     Supt (Ret.) Koa is a qualified Primary Instructor and the Assistant Director at the American Institute of Polygraph Technology and Forensic Psychophysiology, Michigan, USA. He has trained a few hundred government polygraph examiners, including those from Singapore, China, Brunei, Malaysia, Indonesia and Thailand. He is the former Vice President (Private) of the Singapore Association of Polygraphers and a member of the British & European Polygraph Association (BEPA).

    For his outstanding service to the Singapore government, Supt (Ret.) Koa has won many national awards, including the Public Administration Medal (Bronze), Minister of Home Affairs Commendation Certificate for work excellence, Good Service Medal, and Commissioner of Police Commendation and High Commendation Certificates.

    For his service to the government after his retirement, he was awarded the Minister of Home Affairs Commendation Certificate in 2003. (Please see photo gallery below.)
