Lena's newest book is available NOW!
Lena is the Founder and CEO of TCG. She is an internationally recognized expert in Human Behavior, Interviewing, Negotiation, Elicitation, Trust-Based Conversational Skills, Body Language, Truth Analysis, Statement Analysis, and Organizational Change Leadership.
Get trained by a validated expert with DECADES of real-world experience in HIGH-STAKES situations. Lena has trained thousands of people, most of whom are on the front lines keeping our country safe from criminals and acts of terrorism. She will teach you her techniques to persuade people to be open and honest - even in life-threatening situations - that only she developed when she was a US Navy Human Intelligence Officer and US Marine Corps interrogator. Why wait to use elite skills that will give you an enviable edge? If you are in sales, an entrepreneur, an investigator, a coach, a leader, or a public figure, Lena will teach you aspects of human behavior that can keep you safe and launch you to personal and professional success. Do not misread any situation again.

Lena took her expertise to the private sector years ago so she could help people and organizations master their verbal and nonverbal communication skills so they can interview with confidence, discover the truth with ease, have fearless conversations, negotiate like a pro, public speak with poise, and lead with expertise. When you know WHAT to say and HOW to say it, you can accomplish anything.
Lena offers two online Master Programs:
Advanced Elicitation and Interviewing & Negotiation
These are 3-month intensive online programs with one-on-one coaching from Lena herself.
Elicitation is an elite human intelligence tradecraft that few know and even fewer teach. Lena is the leading expert in this tradecraft, still training special forces. She now offers this training to the private sector. You will undoubtedly have a powerful advantage because your competitor most likely doesn't even know what elicitation is. Lena will teach you how to obtain the most sensitive information without ever asking a question while gaining respect and trust from others. This is a superpower that is used for good.
Interviewing and negotiation skills are not just for investigating criminal cases or hostage scenarios. They are techniques for anyone in any industry who needs to discover critical information, in a timely manner, validate that information, and negotiate terms that lead to a successful outcome. We use these techniques when hiring new employees or a babysitter. We use them when we buy a car or when we are selling one. We use these skills to obtain information to make critical life decisions.
