Feel strong, calm
and energised again.

You’re exhausted. Overwhelmed. Done waiting to feel like yourself again. Let’s rebuild.

My approach is simple. We work on the foundations - sleep, nervous system, movement, nourishment - and build from there.

Welcome. I’m Cristíona, an Irish-born holistic health coach, longevity mentor, certified personal trainer, and meditation teacher. I studied holistic health with the College of Naturopathic Medicine in London and  nutrition with Cornell University.

For over 20 years I’ve immersed myself in wellness – from bodywork and movement to nourishment and mindful living. I now bring that experience into personalised coaching that creates calm, strength, energy and lasting change.

Testimonials

Results I have helped create

Cristíona helped me understand my nervous system and how to support my body in a much deeper way. She is incredibly compassionate, knowledgeable, and genuinely cares about seeing people thrive. What I appreciate most is that she lives what she teaches and understands it from real experience. I highly recommend working with her if you want to feel more grounded, calm, and supported in your life. Her guidance truly creates lasting change, not just temporary fixes.

I did a one-month health coaching package with Cristíona, and what I liked most was her approach to meeting me exactly where I was at. I had a lot of ideas and big goals, but Cristíona helped me get the basics right first — for me that was building a sleep routine. We slowly built a plan to bring in new healthy habits every week, and she always found alternatives if something didn't work for my lifestyle. I'd highly recommend Cristíona for anyone who needs a kickstart or support in creating and living a healthier life.

Cristíona gave me the confidence and courage to reconnect with my true self. She held the space, looked at my entire life holistically, and turned my wounds and traumas into motivation. The steps were simple but powerful. She didn't miss a thing. Looking back, I can see transformation from the very first session. She is deeply dedicated and will not rest until you reach where you want to be. I couldn't recommend her enough.

I did the 21-day re-set with Cristiona at a time when I was going through a difficult set of challenges in my life. Her course and her guidance helped me to re-balance emotionally and physically and gave me an incredible amount of energy and strength at a time when I needed it most.

I’ve been lucky enough to train with Cristíona on and off over several years, and she is by far the best trainer and mentor I’ve ever had. She genuinely cares about your progress and health, always going above and beyond to support you. I now join her daily Zoom workouts with a small group of lovely people. Her classes are varied, challenging, and fun—you always finish feeling fantastic. We’re all seeing real results.

Cristíona is absolutely the best coach in Ireland if not in the world! She knows very well how to turn a regular training session into a workout you would be proud of yourself and, which would set up your mood for the day ahead!

How it works

The Approach

Nutrition & Energy

2
Movement & Strength
Whether you're rebuilding fitness or starting fresh, we'll find a movement practice that suits your body and builds lasting strength.

Simple, grounding practices - breathwork, meditation, & journaling - to deepen self-awareness, regulate emotions, and feel more connected.
