Our Founder / Chief Executive Officer

Kara Stewart-Mullens is one of the founders and Chief Executive Officer of Neurobiologix and Dr Neurobiologix. Although her past work history and experience lies mostly in the consumer goods management sector, her drive to market and sell products comes very natural to her. Her intense interest and education in psychology led her to choose the field of advertising and sales so that she could understand how the human mind works and makes choices. “If you put yourself in the shoes of the consumer and not as the seller then you will achieve much more success in sales and building relationships.” - Kara Stewart

With over 25+ years of experience, her expertise in sales management, marketing and brand development speaks for itself. Guiding Neurobiologix for 12+ years to be a recognizable and national nutrition brand has been a joy and blessing. With her own family who suffers from moderate Neuro-Immune Syndromes, genetic testing and clean nutritional formulas allows her to give her family and others the gift of quality nutrition with genetic validation that can help someone be their best and improve their health. This is what warms her heart the most. “If I can touch one person with the gift of finding our products then I have done my job.” Now with the validation of nutrigenomic testing and the development of GX Sciences, the thrill of helping people with scientific backing through DNA analysis is the icing on the cake that allows both companies to succeed.

She also shares her passion in faith, health and wellness with her older brother, Dr. Kendal Stewart, by hosting a podcast 'Coffee with Dr.Stewart'. With over 500,000+ downloads the siblings share their stories and Dr. Stewart shares his medical expertise to bring people hope and knowledge to health challenges they may face. She is also a member of the American Academy of Anti-Aging Medicine.
