Why would a prospective client want you to be their keynote speaker or to support their speaking event? What are some compelling aspects of your background/career/experience that we should know about? 

Speaking from past experience, I am sought after for speaking engagements in large part because of my ability to connect with the audience.  I have been told that I am received well because of a rare combination humility, sincerity, intelligence, and ability to connect with an audience in a meaningful way.   

In terms of background experience, I am a 32 year Marine veteran often times I am asked to speak to groups of any particular rank from colonel down to corporal.  I can speak to culture, leadership, management, and life skills.  I have also given presentations on my combat experiences, mentorship, and even niche topics such as a recent engagement with the Association of Government Accountants as part of their leadership development series.  My biography speaks to my experience.  I would highlight that my last three assignments at the general officer level helped me to not only learn the goings on of large and dynamic organization, but also how executives think and make decisions.  Finally, when I am at my best, it is when I am able to engage with audiences in a Socratic fashion.  I enjoy the banter and helping to shape conversations for the audience to learn as we go. 

What are your primary topics/areas of expertise? Some examples may include: Conflict resolution, International Relations, Leadership, Diversity and Inclusion, Cybersecurity, as well as specific countries or geographical regions. 

My primary areas of expertise are:

  • Leadership
  • Management
  • Training
  • Education
  • Learning

in Central and South America, and the Marine Corps; like others, I have a extensive list of other topics I can speak to.

What are some positions you have held in your career that you would like prospective clients to know about?

The Sergeant Major of Marine Corps Combat Development Command/Combat Development & Integration.  In this role, I was the senior enlisted leader for approximately 40,000 Marines and sailors.  Our command was responsible for the Marine Corps’ Title 10 requirements to organize, train, educate, and equip a force of over 220,000 personnel.  With ties to Congress, industry, and academia, I spent a good deal of this tour (2018-2021) learning how to build a ready and relevant force within budgetary constraints.  During this time, I also spent much of my efforts on updating doctrine and codifying our enlisted education continuum.  

What are some speaking events you’ve supported recently?
