Read all 20 reviews"I enrolled in a 3-month program with Juan, and his expertise has been truly remarkable. He's been instrumental in clarifying my nutritional requirements and guiding me towards my goals. My aim was to achieve a leaner, stronger physique while shedding weight, and Juan crafted a comprehensive plan for me. He's been with me every step of the way, even offering advice when I dined out by sending him the menu for optimal food choices. Beyond the dietary aspect, Juan has also been a fantastic mentor for my goal visualizations. His positivity and inspiration have made a significant impact. He regularly provides me with valuable information and resources that continuously fuel my motivation and help me stay on the right track."
"The best thing I've ever done for myself is invested in myself by doing a course with Juan, the health coach. I was 70kg unhappy with my weight and fat. Joined the programme and within 2 and half months I lost 10kg. Juan is amazing, he knows what he is doing, easy communication and he is best at what he does. Highly recommended!!"

"Working with Juan was a pleasant experience all around and I recommend his services to anyone looking to take their wellness up a notch. Being new to Chiang Mai, and needing help navigating eating out (because I don't have too much space to cook at home), Juan was filled with great recommendations to eat balanced meals on the go, at my workplace cafeteria, ordering in, and simple ideas for cooking in limited space. He took the time to answer questions, provide motivational content and useful templates, accountability checks and advice. He was attentive to my goals and responsive to feedback, making new suggestions to the meal plan. The app Juan uses with his clients makes following the plan really simple! We met up several times to check in on my progress which ultimately helped to address any ongoing challenges or refocus. Lastly, the skills Juan reminded me to implement and knowledge he shared are implementable on my own moving forward. I think that's the beauty of a good coach! Thanks Juan 😊"
