My name is Katarzyna Booss-Cortez. I am a Certified Functional Medicine Practitioner and Certified Transformational Nutrition Coach. I am dedicated to helping people living better and healthier lives by balancing their biochemical imbalances, taking care of nutritional deficiencies and supporting their immune systems. I support my clients by using certified herbs, high-quality supplements, dietary modifications, and most importantly, addressing the root cause of the problems in the most natural way possible.

My path towards becoming a nutritional coach and Functional Medicine consultant began, like many others, with my own personal adverse health issues.  For many years, I suffered from Hashimoto, an autoimmune condition. After receiving this diagnosis, I visited many doctors, but my chronic pain and fatigue never improved. I decided to research and educate myself in hope of finding ways to feel better. This led me to the field of Holistic Nutrition and Functional Medicine and found many answers for my health issues.  With time, my condition improved; I started to feel much better and living happy again. I found myself fascinated with this approach and it became my passion to learn as much as I could so I could further help myself, family and friends.  Now, I want to share my knowledge and experience to help others.

We provide professional and highly advanced laboratory testing and work with top laboratories in the USA and Europe. We work with many Functional Medicine laboratories and supplement companies to provide the best service.
