About me
Hi, I’m Mark
Fluent in Tech is my coaching practice. I help people in tech communicate well enough to get hired, get promoted and lead.

Why I do this
I work one-to-one with people in tech when something important is coming up: an interview, a step into a more senior role, working with a team in another country, or a conversation they can’t avoid.
Before coaching, I spent more than ten years in sales operations, revenue operations, program management and consulting, at Caterpillar, Google, KPMG and Tufts University. I also founded a language center, a non-profit and a software agency, and I’ve been teaching and coaching since 2018. I’ve sat in the same interviews, sales calls and executive meetings my clients are preparing for, so I coach from how tech teams, clients and leaders really work. See my full resume ↓
My sessions are practical and personal. I’m not trying to make you sound like everyone else. I want the people you work with to understand your experience and act on it.

How I coach
What to expect from me
Your background is an asset
I won’t try to erase your accent or your style. I’ll help your experience land with the people who need to hear it.
You leave with something
A story, a script, a structure or a decision. Something you’ll use at work, not just notes.
PAR and role-play
Problem, Action, Result gives your answers and updates a clear shape. Role-play makes it second nature.
You try it again
After my feedback, you do it again, better. Changing what you actually do is the whole point.
A little work between sessions
Short, practical tasks between calls keep you moving forward.
How we’ll work
From the free consultation to regular sessions
A free consultation
We talk about your goal, your timeline and whether I’m the right coach for you.
Where you are and a plan
In the first session I see where you are, and we build a plan around your goal.
Regular sessions
One-to-one on Google Meet, ideally the same day and time each week.
A monthly review
Every month we check your progress against the plan and change it if needed.
