        Harlin Parker, President


Harlin holds a bachelors degree in Criminal Justice from Rutgers University. He received his graduate paralegal training at Adelphi University.  And he received extensive training in criminal justice and accounting practice at New York University and at John Jay College of Criminal Justice. 

He has been a respected investigator, researcher and litigation specialist for more than 30 years.  After 4 years as a paralegal and the managing clerk with a law firm in New York, where he specialized in estate settlement, civil litigation and commercial transactions, Harlin started his own service company in 1983.  Over the ensuing years, Harlin has built a reputation as an efficient and capable investigator, known for his unshakable honesty and integrity, as well as strict adherence to both the letter of the law and the spirit of due process. 

Unlike most private investigators, Harlin’s experience comes not from working in law enforcement, but from his work on behalf of law firms, private businesses and government agencies in civil and commercial matters. He understands the legal as well as the practical and business concerns of attorneys and their clients.  He has worked, directly or through counsel for:

  • Heads of State
  • Officials in high office
  • Royalty
  • Very high net worth individuals
  • Investments Firms
  • Private Equity Firms
  • Major public corporations
  • Private businesses
  • Academic organizations
  • Not-For-Profit organizations
  • Animal Rights organizations

In addition, Harlin also holds a private pilot certificate in the United States, flying single engine Pipers.

Harlin provides many hours of pro bono time to those causes closest to him:

  • Animal rights
  • Children’s rights
  • LGBT rights.


“I have known and worked with Harlin for more than 24 years. He’s a serious, knowledgeable professional who surrounds himself with capable and experienced personnel. Above all, he’s honest and straightforward. No matter what request I make of him, if he says he can do it, he can.  I trust him completely.”
