We offer training and consulting services in the following areas:

  • Advanced Strategic Interviewing & Interrogation: Lena created a strategic non-accusatory method of interviewing that she trains law enforcement around the country.  Her techniques have proven successes in the field. She teaches her interviewing method to anyone who needs to gather truthful information: financial auditors, professional recruiters, sales personnel, and more.

  • Comprehensive Deceptive Analysis (Verbal & Nonverbal): Learn accurate behavioral indicators of stress and deception, and how to identify the difference between them so you do not falsely accuse someone of lying. Lena is a leading expert in this field.  She has conducted hundreds of interrogations and interviews on terrorists, criminals, and litigants.

  • Elicitation and Counter-elicitation: This elite tradecraft is for business intelligence professionals as well as military intelligence. We teach this skill guided by a moral compass.  If you want a competitive advantage in your industry, this is the tradecraft you need to gain high-value information while safeguarding your own.

  • Body Language intelligence: There are many organizations that teach body language, but are they, experts? Lena has over two decades of real-world experience in accurately assessing body language in life-saving situations. She even discovered a few 'tells' no one else teaches in her research.  She teaches "Body Language Intelligence," techniques that debunk myths and common perceptions. 

  • Advanced Leadership Competencies: Lena trains government agencies and law enforcement in leadership competencies based upon decades of research in leadership fundamentals and behavioral science.  Lena received her certificate in the Psychology of Leadership from Cornell University. 

  • Change Management & Organizational Systems: Lena is certified in OCM and in Barry Oshry's Organizational Workshop, which focuses on partnerships and systemic conditions that can cause partnerships to fall apart.
