"Whenever you enter a relationship with a supplier you wonder about whether or not they can be trusted to do what they say they will do. Will they be available when I have questions? Will the level of service fall off after a period of time? Will the quality of work deteriorate? Definiti has never disappointed me in any of these areas. They are serious about their mantra of keeping clients for life. During the entire time span of my relationship they have met or exceeded my expectations. When I have an issue or question they are prompt with a response and not only to us but to our provider as well.

Definiti has excellent turn-around time. They respond to problems within 24 hours. The quality of service has been consistent and constant with no drop-off. To summarize I would say that the people at Definiti have the highest of integrity simply because they follow-up, follow-through and most importantly they do what they say. I would gladly recommend Definiti for your medical bill review needs."
