Investigation and Security...... Welcome to Merloc

We’re here to help you obtain the information you need.

If you suspect someone close to you at work or at home may be deceiving you, the first step is to talk to us. Our expert team has over 85 years experience, and we’re here to help secure the evidence you need to make a decision about your future or to put your mind at ease.

Our initial consultation is free and there are no obligations. You’ll be able to talk through your individual situation with an expert, and be given advice on what to do next. We work with clients on domestic and corporate investigations, offering tailored support and business advice as needed.

Though we help clients in many different ways, we uncover the truth in every investigation.
