Jeff Johnson
Founder & Principal Consultant
Quantum E-Discovery

Jeff believes in saving time and money in e-discovery by applying a variety of analytics tools early in a case, well before moving content to expensive final review platforms. Over the past 20+ years he has accumulated a variety of tools that can be applied as needed in specific situations. Having invested his time and money in acquiring and learning how to use those tools, he is often able to provide alternative workflows and pricing models that result in lower and more predictable overall costs to corporate clients.

In addition to handling email and unstructured content, Jeff has unique expertise in extracting, analyzing, and producing data stored in structured data sources.
