ABOUT
I Did Not Wait Until the Uniform Came Off.
Nicholas “Rhino” Rinell | Master Sergeant, USMC | MBA

I enlisted in the Marine Corps because I believed in something larger than myself. Twenty-two years later, that belief has not changed; only the arena has expanded. I have spent my career leading people through complexity, holding standards when it would have been easier not to, and building the kind of culture where excellence is not an event but an expectation.
I came up through Air Traffic Control Maintenance, a discipline that does not tolerate imprecision. When systems fail in that environment, people die. That reality shaped how I think about leadership, accountability, and the cost of cutting corners. It is not abstract for me. It is the foundation on which everything else is built.
Over two decades, I have served across multiple commands, developed hundreds of Marines, and eventually taken on the role of Air Traffic Control Maintenance Chief at MCAS Camp Pendleton. That assignment is not just a title. It is the culmination of a career spent earning the right to be the standard-bearer and the responsibility to build the next generation of people who will hold it after me.
Several years ago, I made a decision that changed my trajectory. I enrolled in college, eventually earning a Bachelor of Science in Cybersecurity Management and Policy from the University of Maryland Global Campus and a Master of Business Administration in Information Technology Management from American Military University, not because I needed a credential, but because I wanted to understand the language of the civilian world I was eventually going to enter. What I found was that the frameworks I had lived inside the military, systems thinking, organizational behavior, and leadership under pressure, had names in the academic world. I had been doing the work. The degree gave me the vocabulary to articulate it.
That realization led to the next one. If I understood this material well enough to apply it under fire, I understood it well enough to teach it. I joined the faculty at the Dr. Wallace E. Boston School of Business at American Military University as an adjunct faculty member, teaching undergraduate students the basics of business. Walking into a classroom, even a virtual one, and watching someone understand something for the first time is one of the most satisfying things I have done in uniform or out of it.
Outside the classroom, I serve where the work is. I am President of the AMU/APU chapter of Student Veterans of America, where Tommy Hendler and I write The Rally Point, the chapter’s monthly newsletter. I serve as Vice-Chair of the APUS Military Advisory Council and as Secretary of the San Diego Military Advisory Council Foundation board, and I am a certified RBLP trainer (RBLP-T). Tommy and I also co-host the Rally Point Actual podcast.
The Keep came next. I started the newsletter because I had things to say that did not fit inside a rank structure. Leadership, standards, transition, identity, the parallel build: the things that matter to people who are serious about what comes after service. The motto is Hold The Standard. That is not a tagline. It is a way of moving through the world.
I have completed my MBA and am currently exploring doctoral programs, with research focused on how resilience frameworks from high-reliability military organizations translate into civilian performance contexts. The work I do in the classroom, in the newsletter, and in the field all points toward the same question: what does it actually take to build people who hold the line when it matters?
I am not waiting for retirement to become who I am going to be. I am building now, in parallel, with the same deliberateness I brought to every assignment the Marine Corps gave me. If you are here because you are curious about that work: welcome! If you are here because you are building something yourself and want to talk: reach out.
