I have known Tom Martin and used his services for many years. I trust him with the most challenging investigative tasks.

Professional and efficient, he and his staff leave no stone unturned to get the job done.

It has been my pleasure to work with Martin Investigative Services over the past 30 plus years on many investigations as well as other security related matters. When I need answers and I need them fast I know that a simple call will get me answers that are succinct, current and coming from a supremely knowledgeable source.

I've always received swift, cost-effective and USEFUL information, which has wound up "saving the bacon" of our clients and making us shine in their eyes. I recommend them without any reservation.
