Turning technical expertise into compelling communication
How Andrei Dragomir grew confidence and credibility through public speaking coaching
Client overview
Andrei Dragomir is the founder of a deep-tech start-up, spun out of the University of Southampton’s Integrated Atom Chip research group. His company, Aquark Technologies, develops miniaturised quantum systems for position, navigation and timing (PNT) in GPS-denied environments. The team is focused on making advanced sensing technology smaller, more accessible and commercially scalable.
The challenge
With a background in physics, nanotechnology and quantum research, Andrei is an expert in his field—but public speaking didn’t come naturally. As CEO of a growing company, he found himself increasingly required to:
- Present his vision clearly and confidently
- Speak at high-level industry events and conferences
- Represent the company to investors, partners and policymakers
- Communicate complex ideas to non-technical audiences
- Lead his team with clarity and presence
He recognised the need to build his confidence and accelerate his development as a communicator.
The solution – action taken
Over the course of around 12 one-to-one, mostly face-to-face sessions, Andrei worked with Sarina Mann to improve his speaking and leadership communication. The program included:
- Techniques to manage nerves and reduce anxiety before speaking
- Strategies to build stage presence and carry himself with confidence
- Practical preparation tips—understanding the space, audience, and tech
- Tools to structure and deliver clear, engaging messages
- Coaching on leadership communication and giving feedback to his team
- Emphasis on self-acceptance and leaning into his strengths
Results – outcomes and benefits
The transformation was both practical and personal:
- Andrei now speaks confidently at industry panels, investor pitches, and scientific forums
- He’s more comfortable presenting impromptu and adapting to different formats
- He stands out by interacting naturally with audiences—moving around the space, stepping away from podiums, and creating connection
- He’s reduced physical signs of anxiety and learned to accept silence and pauses in speech
- He’s more effective not only on stage but also in day-to-day leadership communication
Client testimonial
“Before I worked with Sarina, my instinct was to avoid public speaking. Now, I’m far more comfortable on stage—and more importantly, I’m confident in who I am while doing it. The sessions helped me understand how I carry myself, manage my nerves, and accept that what I have to say matters. It wasn’t just about public speaking—it was about communication, leadership, and presence. That’s had a huge impact.”
Conclusion – summary and future outlook
Andrei now regularly represents Aquark Technologies at global conferences, investor events, and high-level panels. His improved communication skills have helped him make stronger connections, attract collaboration opportunities, and build credibility for both himself and the business. From struggling with stage fright to thriving in the spotlight, his journey shows how the right support can unlock real growth—both personally and professionally.
