george lockhart

Co-founder and Nutritionist

Growing up overweight, George became interested in athletics and nutrition to improve his personal health. Little did he know at the time, but George would eventually become influential in the nutrition field. George’s background in nutrition and its application ranges from his firsthand experience as a professional fighter handling his own cuts, to leading the Marine Corps in nutrition, and finally to handling weight cuts for hundreds of UFC fighters worldwide.

George completed 10 years in the United States Marine Corps in the Radio Reconnaissance community. During his time in the Marine Corps George deployed to multiple combat zones and became an impactful piece to the Martial Arts Center of Excellence and the Marine Corps Martial Arts Program. George spent four years as a Martial Arts instructor and Combat Conditioning Instructor Trainer for the Martial Arts Center of Excellence. While in that position of leadership George’s passion for nutrition and hydration set him up to become a nutrition and hydration expert. He completed the requirements to become a Tactical Strength and Conditioning instructor in hydration and went on to lead the development of nutrition and hydration curriculum taught throughout the Marine Corps. George completed his tour at the MACE with a Navy Achievement Medal for implementation of the Marine Corp nutrition curriculum.

Throughout his Marine Corps career George competed as a professional fighter in 4 different weight classes. Finishing with an overall record of 11-7 across the 4 weight classes George realized his expertise was more in the nutrition and weight cut realms and adjusted his focus accordingly; however, not before becoming the American Fight League World Champion.

George has worked with hundreds of professional and amateur fighters, bodybuilders, Olympic athletes, and several Hollywood celebrities; helping clients achieve every type of goal underneath the health and wellness umbrella. Over the past year, George and cofounder Dan Leith have created a Lockhart and Leith team that share the unrelenting passion and drive for pushing clients to be the best they possibly can be. Whether its professional fighters, young athletes with the dream to one day represent their country, celebrities, or people with the desire to improve their own quality of life, the Lockhart and Leith team has the experience and passion to bring the champion out in everyone.


Dan Leith

Cofounder and Nutritionist

Dan’s passion for nutrition and the development of safer weight-cut practices came about early in his life. Dan experienced, firsthand, the very real danger involved in the nutrition and weight-cut procedures for weight class related sports. As a young man Dan, nearly died from renal failure while cutting weight for a wrestling tournament. Since that moment he has made it a personal mission to ensure others don’t make the same nearly fatal mistakes he did.

Dan is a United States Marine Corps infantry veteran and Bronze Star recipient with Combat “V”.  During his time in the Marine Corps, he became the subject matter expert in nutrition. Dan instructed thousands of Marines, Officer and Enlisted, at the Martial Arts Center of Excellence in Quantico, Virginia as part of the Marine Corps Martial Arts Program. Dan is a Certified Combat Conditioning and Nutrition Specialist and has trained under some of the best minds in Nutrition and Strength and Conditioning.

Dan began his work with UFC athletes with clients including Light Heavyweight champion Daniel Cormier, two-time Heavyweight champion Cain Velasquez and Middleweight champion Luke Rockhold. Most recently, Dan spent a year working as a nutritionist full-time for Grammy nominated recording artist Demi Lovato.

While his roles as a cofounder have changed from the weekly fight week grind, Dan continues to push the Lockhart and Leith team to ensure the highest quality service, and most up to date scientific information, is provided to our clients. Together with his partner, George Lockhart, his goal is to pass on the knowledge and experience they have gained during their time with combat sport athletes to all of the aspiring trainers, nutritionists, and coaches across the globe.
