John Marshall
MS, PCC, NBC-HWC
Integrative Leadership & Executive Coach

"Calm, candid, systems-informed coaching for leaders who want sustainable success amidst rapid change."

I work with self-aware leaders who carry real responsibility and want to lead with more clarity, steadiness, and impact.

Many of my clients are directors, senior managers, and rising executives navigating growth, organizational complexity, transition, or greater visibility. They are already capable and committed. What they need is a thoughtful space to think clearly, uncover the patterns shaping their leadership, and strengthen how they communicate, decide, and show up under pressure.

Before coaching full-time, I built my business background in strategic accounts and business development at ExxonMobil, where I led both national and global accounts, complex negotiations, and cross-functional collaboration in high-stakes environments.

My coaching is calm, candid, and structured. We do not just work on surface-level tactics. We look at the patterns beneath performance, including how you relate to stress, conflict, expectations, boundaries, confidence, and self-trust. The goal is not just stronger performance, but a more grounded, sustainable way of leading that does not require sacrificing your values, well-being, or relationships.

We enjoyed our Team Building session with John. He made our session easy, fun, and comfortable. It was nice to be able to get together and share on a personal level which our staff rarely have time or the will to do. Our Team is actually looking forward to our next Team Building...sounds like a plan to me!

John quickly became one of my key sources of support and guidance as I moved from the most challenging and painful chapter of my life into what I now consider to be the happiest and most successful just a year later. John is a highly gifted coach, with the ability to continuously adapt his approach as he learns which parts of me need to be protected and accommodated and which parts are ready to be challenged and reshaped. For anyone looking to make a change in their life who is even remotely curious about the benefits of having a coach, do yourself the biggest favor and reach out to John.

Working with John is a pleasure as his work is both experiential and academic. We collaborated on a training project and John designed, developed and delivered the mindfulness module. He not only delivered an impactful and engaging program that met our specifications, he did so through a virtual platform with global participants. No small feat. I also learned from him as his teachings are simple, profound and memorable.
