About Sarah

Sarah is a certified holistic nutritionist & practitioner. She is currently living in Dallas, Texas.


She is currently obtaining her Master of Science in Human Nutrition and Functional Medicine at the University of Western States. The human nutrition and functional medicine (HNFM) program at the University of Western States (UWS) is the only fully accredited master’s program in functional medicine and is a collaborative endeavor between UWS and the Institute for Functional Medicine (IFM).

Sarah graduated with honors with a Bachelor of Arts in communication and integrated marketing from Canisius College. It was during her undergraduate studies that she identified her strong passion for health and wellness through her human anatomy and physiology, and kinesiology courses.


Soon after graduating from college, she began the Institute for Integrative Nutrition's program. Upon completion, she created NTG to share her knowledge and passion for healthy eating and nutrition. From there, she enrolled in the Nutrition Therapy Institute (NTI) in Denver, Colorado to become a Master Certified Nutrition Therapy Practitioner. 


Sarah is the founder of Nourish Thrive Glow, Inc. an integrative nutrition consulting business and private practice focusing on healthy,  nutrient-dense, practical recipes, all while leading a clean, holistic lifestyle.  When she isn’t working with her clients, you can find her working out, experimenting with new recipes, or traveling with her husband and German shorthaired pointer, Sydney.

Her Philosophy


Sarah's strong passion for nutrition and wellness grew out of her own health problems - bloating, acne, fatigue, low energy levels, and weight fluctuation (weight loss and gain).  She went to countless doctors who overprescribed medications to treat her symptoms with little to no relief. Exhausted and fed up, she turned to food. Yes, food!

It was through the addition of real nutrient-dense foods as well as crowding out the deficient ones that she was able to address the root cause as opposed to treating only the symptoms. 

Her philosophy is all about nourishment - not deprivation. She focuses on creating a livable regimen that allows her to enjoy life while still feeding her cells and nourishing her body, and does the same with each one of her clients. 


Sarah challenges her clients to stop viewing food as the enemy, and instead to see it as energy, the building blocks to our life – as one of the most essential parts of our lives. She believes health is not a one-size-fits-all approach and should be customized to one’s bio-individuality.


She works with clients from all walks of life and all over the world to help them create and sustain a routine that works for them. Sarah works with clients to not only help them build their meals but to better understand the power of food and its impacts on our entire body. When her clients begin to understand how food works, it provides them with a roadmap and the tools necessary to support their lifelong health journey.
