Why Work With Me?

“Immense thanks to Santiago Rosin who helped me get back on track with nutrition, by reminding me of important factors I seem to have forgotten (or never knew!). Such as the importance of consuming more protein, factors that impact iron absorption, and, my favourite, the role energy density plays in managing weight and appetite. I've been reading about healthy eating for some time, trying to shift weight that just wouldn't budge, but it was our conversations that did the trick. Thank you, Santiago, for your generous advice, support, and expertise.”
— Jeanne H.

“I cannot recommend my nutritionist, Santiago, highly enough! He is truly the best. I had been struggling with stomach issues for a long time, and nothing seemed to help. However, after working with him, I have seen incredible improvements. He took the time to understand my specific needs and created a personalized plan that has made a world of difference. His expertise and dedication are unmatched. If you're looking for someone who genuinely cares about your health and well-being, look no further!”

More About Me

Outside of my work as a dietitian, I’m an active and curious person. I love all kinds of sports—from gym workouts to combat sports and soccer—because movement is key to my personal balance. I’m a big coffee enthusiast; it’s a daily pleasure I never tire of. I also love to travel, especially when I can discover new cultures through their cuisine. Reading is another favourite pastime, whether to relax or deepen my professional knowledge. I enjoy being outside in the sun and am always excited to try new foods or supplements, often to better guide my clients.
