About John

Former McKinsey Engagement Manager and U.S. Marine Corps Captain with a track record of leading teams and solving complex challenges in high-stakes environments. I specialize in resume development, interview preparation, and career strategy, helping professionals clearly articulate their value, navigate competitive hiring processes, and accelerate their career trajectory. Living in Pittsburgh with my Wife, son and cat :) Go Steelers, Go Blue!

Why do I coach?

I coach because career moves can feel surprisingly hard to navigate alone. Sometimes you need someone who can help you see your strengths more clearly, sharpen your story, and approach big opportunities with more confidence. I genuinely enjoy helping people make sense of their experience and take the next step with clarity.
