Garrett Serd “Coach g”

Founder of Tandem Nutrition

Garrett Serd, MS, RD – Founder & CEO of Tandem Nutrition My clients and friends know me as Coach g. My passion for nutrition and fitness began in 2004 at the age of 16, during my personal battle with anorexia nervosa. It was a fight I knew I couldn’t win alone, but through relentless determination, I committed myself to learning everything I could about nutrition, fitness, and sustainable health. That passion led me to pursue a Bachelor of Science in Nutrition & Dietetics from Louisiana Tech University and a Master of Science in Nutrition & Exercise from the University of Nebraska-Lincoln, where I also became a Registered Dietitian. Additionally, I hold certifications as a Certified Personal Trainer and Certified Wellness Coach through the American College of Sports Medicine.

In 2012, I founded Tandem Nutrition, driven by a mission far greater than myself—to help women break free from restrictive dieting and finally achieve sustainable fat loss. Over the years, my team and I have helped thousands of women transform their bodies, boost their confidence, and regain control of their health through our unique Metabolic Reset System. Every day, I wake up with excitement and purpose, knowing that I have the opportunity to serve and impact lives. Through the relationships God has placed in my path, I’ve been blessed to build an incredible team that shares this same passion. Together, we are changing the way women eat, think about food, and achieve lasting results—one life at a time.
