About Me
Brittany Bettingen, MS RDN LN
My name is Brittany Bettingen, I am a registered dietitian nutritionist who completed a masters of science in Nutrition, Healthspan and Longevity from the University of Southern California (USC).
My passion is in integrative and functional medicine. I am a Functional Medicine trained Dietitian through The Institute for Functional Medicine. I approach patients using these principles and individualize my plan based on each patient’s needs. I love helping my patients move from a place of confusion and frustration to a place of empowerment and confidence as they learn to make the best health focused decisions for their body.
My journey to become a registered dietitian has been a long time coming and officially started in 2015 when I began transitioning from a career in marketing to my true calling of helping others lead a healthier lifestyle through preventative health and nutrition. Like most people in this profession, I have had a history of personal health challenges that ignited my fire to practice nutrition. These health challenges have led to my deep conviction in the power of food as medicine.
Fortunately, my experience has allowed me the ability to understand what it is like to be in the shoes of my patients with health challenges, and what it takes to recover. With the skills I have learned by becoming my own health detective, I hope to help you decode your medical history. I will help you connect the dots to your health symptoms and try my absolute best to get to the root of your health concerns through evidence based science, the latest research, the right functional testing and my intuitive ability to piece the puzzle together.
My process is about personalizing what works for your body! I help you implement purposeful dietary and lifestyle modifications that will continue to provide you lifelong health benefits long past your initial health crisis has been healed.
If you aspire to get to the root of your health concerns and would like to work with someone who has been through it, came out on the other side and has the credentials to back it up, then I am your girl!
