An event that changes the way you understand your health

I was especially interested in the topic of hormones.
The most important educational event of the year. Barbara O’Neill personally reveals how to understand health and the body on a deeper level
A unique educational event where Barbara O’Neill personally shares her knowledge and reveals the key principles of understanding health
This event does not bring just another list of tips. It helps you understand why the body reacts the way it does.
- For years you have been trying to “do the right thing,” yet the results are missing
- You feel overwhelmed by conflicting information about health
- You feel that you may have damaged or “exhausted” your body
- You are tired of constantly trying to fix symptoms
- Your real problem may not be a symptom, but the loss of understanding your own body
- You may not know how the body truly functions as a whole
- You may have lost trust in authorities, yet still search for reliable guidance
- You carry guilt because of your past choices
This event is intended for women and men who have tried many approaches over the years but still feel they lack a complete understanding of their health.
Ticket presale is open. Seats are limited.
Barbara O’Neill I Zagreb I June 2–4, 2026. Hotel Antunović is not just the venue of the event. It is a modern congress space where knowledge is shared, experience deepens, and the atmosphere allows full concentration and inspiration.
A venue that elevates the experience. Hotel Antunović in Zagreb is one of the best-known congress hotels in the region and an ideal environment for an event that gathers people from across Croatia and beyond.
Spacious conference halls, professional technical equipment, and a carefully designed environment create a space where participants can fully focus on learning and the experience of the lectures.
Hotel Antunović is known for its modern infrastructure and excellent organization of business and educational events.
Located on Zagrebačka Avenue, the hotel is easily accessible for participants from Zagreb, across Croatia, and the wider region.
This event does not offer quick fixes. It restores understanding
Barbara O’Neill does not add more advice to an already overwhelmed mind. She brings back the fundamental understanding of the body — without pressure, without guilt, and without the need to be perfect.
Understanding instead of rules
At this event, restrictions are not handed out.
Instead, you gain a clear understanding of how the body functions as a whole.
Once the root cause is understood, the confusion between contradictory advice disappears.
Working with the body, not fighting it
The focus shifts from exhausting regimes to listening to the signals of the body.
Feelings of guilt disappear, replaced by inner calm and confidence in your own decisions.
The feeling that it is not too late
Understanding the regenerative abilities of the body restores psychological safety —
the realization that change is not reserved only for those who started earlier.

You might be wondering … these are the most common questions people have before deciding to attend
If you recognize yourself in some of these thoughts, it does not mean you are skeptical. It simply means you are careful and responsible toward yourself.
Will this experience bring real change or just a short moment of inspiration?
The fear that we will listen and understand, but not know how to apply it.
Sensitivity to messages that sound like guarantees or “solutions for everything”.
The fear that without radical changes nothing will make sense.
What the Barbara O’Neill event in Belgrade looked like. This is an experience that cannot be explained with words.
“Many things were already familiar to me, but it is always valuable to hear them first-hand. She spoke about hormones, which was the topic that interested me the most. She clarified many doubts for me.”
This is the atmosphere we are creating. Come and feel what it will be like in Zagreb.
If you feel this resonates with you, the next step is simple.
Seats are limited, and the Early Bird price is available only for the first registrations.

FAQ – The most common questions before attending. A few more answers that may help you make your decision.
Is this event for me if I am just beginning to explore this topic?
Yes.
The event is designed to guide you from the basics toward a deeper understanding, without pressure, without unnecessary complexity, and without the assumption that you “already need to know.”
Will this be another lecture offering quick fixes?
No.
This is not an event that offers shortcuts.
Instead, it restores understanding, connection, and clarity — the things that last in the long run.
Is the content the same on all three days?
No.
Each day focuses on a different topic and builds on the previous one, allowing for a deeper understanding and connection between the themes.
That is why the three-day ticket offers the most complete experience of the event.
Can I ask questions during the event?
Yes.
Time is reserved for questions and for integrating the content, and the VIP experience also includes the opportunity to ask a personal question.
Is the event suitable if I come alone?
Absolutely.
Many people attend on their own, and this is often when the most meaningful personal shifts happen.
The atmosphere is safe, calm, and welcoming.
Is there a limited number of seats?
Yes.
The number of participants is limited in order to maintain the quality of the experience, especially for VIP tickets.
Will there be breaks and time for conversation?
Yes.
The rhythm of the event is designed to give you time to listen, reflect, and integrate the content — not just receive information.
What if I change my mind after purchasing a ticket?
The terms for refunds and exchanges are clearly stated during the ticket purchase process, so you can make your decision calmly and with confidence.
Why do ticket prices differ?
All tickets grant access to the same event.
The difference lies in the depth of the experience, the level of proximity, and the space you have during the event.
How do I know which ticket is right for me?
If you would like a basic experience and attend only part of the program – 1 day.
If you want a deeper and more complete understanding – 2 days.
If you want the full journey through all topics – 3 days.
If you are looking for closeness, exclusivity, and a special experience – VIP.
Is this an event that changes your life or just leaves a good impression?
It does not promise overnight change.
But it often changes the way people think — and that is what truly lasts in the long run.
Will I know what to do next after the event?
The goal is not to create confusion, but to bring clarity. Most participants leave with a sense of direction and inner peace.
