Experience, experience, experience.   Gailey Associates has been in business since 1989.  Our team has handled a broad range of investigations and has worked for companies across the spectrum of industries.


Our team routinely attends continuing education courses to stay abreast of current statutes and industry standards.  One of our investigators is also an attorney who was in civil litigation practice for 15 years and who has experience trying cases to jury verdict.  This education and experience provides a solid base for training our investigators to be able to anticipate the needs of our attorney clients.


Gailey Associates many times succeeds when other investigators have not because our investigators keep working.  Those difficult to locate or serve witnesses are our specialty.


Because acting with integrity is the right way.  Gailey Associates understands that we are representing our clients in the field and our actions reflect back to our clients.  We understand that our actions may make the difference between the admissibility or non-admissibility of evidence.  Our clients can trust Gailey Associates will act with integrity.
