About the Method

How the Expert Method Benefits You

Whether in private practice or public defender offices, investigators often work in isolation.

With most training and conferences tailored to attorneys, investigators are often left without a comprehensive resource.

We could not find a training program that could equip our team with the tools needed to investigate thoroughly and in line with best practices. So, we created it, and now we’re sharing it with you.

What People Are Saying About Expert Method

Glenn McClister

I’m a public defender and I also run the advanced investigator training for Kentucky’s statewide public defender system. I can say without qualification that this class is wonderfully designed and produced… full of the kind of practical advice one can only get from seasoned professionals. I highly recommend it!

William Jackson

The investment in taking this course is walking away knowing the information obtained will help make a significant impact in the lives of others.

Eleanor Kagan

Coming from journalism, I thought I knew a fair amount about investigative research, but this course blew my mind wide open. Through in-depth examples and engaging storytelling, I learned so much about the tools, methods, and ethics around background investigations. There’s a real art to this work, and I’m grateful for the supportive, informative, and fun way AKI handed me a paintbrush

Megan Wartner

This course equips legal professionals, including paralegals, with the skills to confidently conduct thorough investigations and provide critical support to attorneys in building stronger cases

Martin de Bourmont

By putting all of these lessons in the context of a case in progress, the investigator learns in a hands-on way that favors retention and understanding.
I cannot recommend this program highly enough.
