Katie McKersie


Katie works with women all around the world specializing in healing acne & other skin conditions. Through her business, Holistico, she has helped many women address their underlying hormone & gut issues to become acne free. She has a great deal of experience working with conditions such as; Polycystic Ovarian Syndrome, Post Birth Control Syndrome and Small Intestinal Bacterial Overgrowth (commonly diagnosed as IBS). Her clients not only see drastic improvements in their skin but also an improvement in other symptoms like hair loss, hirsutism, excessive gas/bloat, weight gain and fatigue. Katie knows first hand how demoralizing acne can be as she suffered from both hormonal cystic acne and digestive fungal acne after coming off the birth control pill in 2018. She tried every topical and medication out there only to discover improvements when she balanced her body internally using nutritional strategies. Katie also studied functional medicine and now experiences great success running functional lab tests to find her clients root cause(s) so achieving clear skin is no longer stressful.


I chose CSNN to study holistic nutrition due to the positive feedback I got from past alumni. As I was new to the natural wellness space, I wanted a community to support and uplift me. CSNN was exactly that. I found the teachers to be very informative while maintaining a more hands-on and discussion-based learning approach which I greatly appreciated. I couldn’t be happier with the practical knowledge gained from CSNN and the lifelong friendships built.
