Why Take a Writing Class?

After 20 years of reading reports written by educated professionals in various career fields, I have learned that many people are experts in most facets of their jobs, but they often struggle to convey their work in a well-written report. My program seeks to teach your employees how to apply advanced writing principles to the specific reports they produce for your department.

What Do I Teach?

I focus on how to improve the readability, accuracy, and conciseness of the students’ reports. I also address how to write for a specific audience, how to correct common grammar errors, and how to integrate useful visual tools into reports. I pay particular attention to teaching proper editing techniques that will dramatically improve writing performance.

How Do I Train?

The training atmosphere is enjoyable and relaxing, ensuring everyone is actively engaged in the class. I integrate practical exercises that offer students an opportunity to practice what they learn and allow me to provide critical individual feedback to improve everyone’s writing. I tailor the training to the specific needs of your department or office.

Investigative Skills

Whether your staff or department needs refresher training, or you have new employees who need to learn fundamental skills, I can provide critical training to improve your organization’s investigations.  Specializing in interview techniques, identifying important information in documentary evidence, determining appropriate investigative techniques for unique cases, and effectively presenting the results of an investigation to the decision makers, my engaging classes will enhance the investigative results of your staff.  Contact me to schedule a training class for your investigators.


I have provided presentations to local, state, and federal government conferences, as well as corporate, non-profit, and member organization conferences.  As you can see from the testimonials below, my presentations are engaging, informative, and well-received by conference attendees.  I can adapt my presentation to the needs of your audience, but common topics include case studies of captivating major corruption investigations, contract and fraud investigative techniques, and report writing refresher training.  Contact me to discuss the needs for your next conference.


about me

I retired in 2021 after serving nearly 25 years as a federal criminal investigator.  As a Special Agent, I conducted diverse investigations involving government corruption, contract fraud, health care fraud, counterintelligence matters, and protective security operations. I am a certified adjunct instructor for the Federal Law Enforcement Training Center (FLETC), and regularly teach search warrant affidavit and report writing classes for the federal Inspector General Academy.  Additionally, I present effective report writing techniques and case studies at government and industry conferences.

Prior to becoming a criminal investigator, I taught English composition at the university level.

I have received multiple awards, including the Agent of the Year award in 2013 and the regional Agent of the Year award in 2007. I was the lead investigator on a major public corruption case that received the Significant Fraud Case award from the Financial Crimes Enforcement Network (FinCEN) in 2017. I received an Award for Excellence in 2012 from the Council for the Inspectors General on Integrity and Efficiency (CIGIE) for my work on a case involving defective battlefield munitions, and I received the adjunct instructor of the year award in 2017 from the CIGIE Criminal Investigator Academy.
