“I attended two public speaking workshops with Diana Bukowska, and I am truly grateful for this experience. What I appreciate most about Diana is her approach to students and teaching. She has a rare ability to make difficult things feel simple, almost like magic. One of my biggest challenges was presenting my project in English.

I thought I would not be able to do it until my English became perfect, without an accent, with perfect vocabulary, and with full confidence. But by the fourth class, I was already pitching freely in front of an audience, holding a microphone, and feeling comfortable.

I honestly do not even remember what I was so afraid of before. For me, it was a life-changing experience.

Diana’s workshops are helpful not only for non-native English speakers. She teaches many important details about how to present yourself on stage, how to hold your body during a pitch, how to use posture, presence, and confidence to create a stronger impression.

And if you can attract and hold the audience’s attention, that can become one of the key parts of your product’s success. On top of that, Diana is a wonderful and warm person. I always left her classes in a great mood, no matter how my day had been before.

I highly recommend Diana to anyone who wants to improve their public speaking, pitching, stage presence, and confidence.”

“I came in convinced my problem was nerves. It turned out my problem was structure — I was hiding behind a memorised script because I had never learned how to hold a message.

I used to script every investor call word for word. Diana taught me how to speak from a structure instead of a script — the pitch finally sounds like me, and the room feels it.

We worked on how I open, how I handle a question I do not like, and how to stop apologising with my body before I even start speaking.

Three months later I closed our seed round, and two of the investors mentioned the clarity of the story as the reason they took the second meeting.”

“In health tech, every presentation carries weight: clinicians, regulators, patients. I had the substance, but I was burying it under forty slides.

I lead a team of twelve and I still dreaded the quarterly review. Now I walk in with a point of view, not a deck — and people actually remember what I said.

The sessions were practical from the first minute. We recorded, we replayed, and I saw exactly where I was losing the room.

What surprised me most is how much of it is the body, not the words. Posture, pace, and where I put my eyes changed more than any rewrite could.”

“Our managers are engineers by training. They know the detail cold, but they were losing the room every single time they had to stand in front of it.

We brought the workshop in-house for our leads. A month on, our all-hands is shorter, clearer, and nobody reads slides out loud any more.

The team format worked because everyone practised in front of each other. It built a shared vocabulary we still use in reviews.

I would run it again for every new cohort of managers.”

“I have been a writer my whole career, which meant I kept trying to solve a delivery problem with better sentences. It never worked.

I can write a keynote in a day. Saying it out loud was the part that broke me. The Voice Lab gave me a room to fail in — safely, and on purpose.

Practising in a small group with people at the same stage removed the shame from it. That alone was worth the price.

I have now spoken at two conferences without a single note card.”

“I avoided conference talks and left the speaking to my co-founder. I told myself it was a language problem.

English is my third language and I let that be my excuse for years. Four sessions in, the accent stopped being the story — the idea did.

What changed was pace and pausing. I used to rush to get the sentence over with. Now I let the room catch up with me.

Last month I gave the opening talk at our user conference. My co-founder sat in the audience.”
