About me
I am a dietitian (Bachelor's and Master's degree in Dietetics from a Polish university; my degree is currently going through recognition in Spain), a personal trainer, and I work from a holistic approach based on Psychoneuroimmunology (PNI).
For over 15 years, I have been helping people improve their health, body composition, and overall well-being. I have studied and worked in Poland, the United Kingdom, the United States, and Spain, where I currently live and practice.
I believe that good health is about much more than food. That's why I consider nutrition, physical activity, sleep, stress, gut health, and hormonal balance to create a truly personalised plan.
As a wife and mother, I understand how challenging it can be to take care of yourself while balancing family and work.
If you're looking for a professional, personalised, and supportive approach with lasting results, I'd be happy to help you.
My full storyHow we work together
-
A free 15-minute chat
You tell me where you're at, what you've tried, and what you want to change. I tell you honestly whether and how I can help. If I can't, I'll tell you that too.
-
I design your plan
Nutrition and training based on your schedule, your budget, what you know how to cook, and what you enjoy eating. Not a generic template.
-
We adjust as we go
This is where diets fail: at the first unexpected event. We review, correct, and keep going. You write to me when you need to, not just on appointment day.
-
You stop needing me
The goal isn't for you to depend on me, it's for you to know how to decide on your own. When you get there, we're done.
Does this way of working sound right for you?
Book a free 15-min callHow the online consultation works
Working remotely raises specific questions. Here are the answers, no fine print.
- Where do we do the session?
- By video call, from wherever you are. You just need a connection and a quiet half hour.
- What if your schedule doesn't fit mine?
- We arrange the video call for a time slot that works for you. The rest of the support doesn't depend on us being available at the same moment: you write to me when you can and I respond with your adjusted plan or a video explaining it.
- What exactly do I get?
- Your nutrition and training plan in writing, the agreed check-ins, and a direct channel with me for everyday questions.
- What languages do you work in?
- We do the consultation in Spanish or Polish, my native language. I also speak English, so if it's more comfortable for you we can use it in sessions — though written materials are delivered in Spanish or Polish.
