My mom and I have worked with Kim for over 6 months now and she has helped us reach our health goals and beyond. It was important to us that we found a nutritionist that was knowledgeable on naturalistic methods alongside traditional and she has created such a balance between the two. We could not recommend her more and as individuals with many sensitivities and in the process of recovering from cancer we trust her entirely. Thank you so much for everything Kim!!

Kim has been the biggest help to me on my journey of recovery from gastritis and a slew of other difficult to manage gastro issues. She is very knowledgeable and attentive, and always looking out for my best interests. We have been working together for around 2 months and I went from feeling the worst I ever had to feeling the best I ever have. I highly recommend her service to anyone looking to heal and get your gut right!

On Ki Chan a.k.a Kim is just an amazing nutritionist. She is so accommodating and pays attention to every detail of your diet and explains everything scientifically on how things can affect your body. She is very sweet and understanding and is very patient. I have lost more than 80lbs after being with her. Will highly recommend Kim to be your nutritionist and make your life healthy.

I’ve been working with Kim for a while now, and she’s truly amazing at what she does! She’s taught me so much about food, nutrition, and how it really impacts overall health — especially gut health. Kim has been incredibly consistent and supportive throughout my journey. She’s always positive, easy to talk to, and genuinely cares about helping you reach your goals. What I really appreciate is that she stays up to date with the latest research and gives information that’s not just helpful but also backed by science. Her explanations are clear and practical, which makes it so much easier to understand and apply what she teaches. Overall, Kim is a pleasure to work with and has made a big difference in how I approach food and my health. Highly recommend her!
