Krissy Mae Cagney

Owner & Head Nutritionist, GLUTEN FREE GODDESS

Krissy was born in Hawaii, but raised in Reno, NV, where she attended high school and college, graduating from the University of Nevada, Reno. Fitness was a part of her life from a young age as her parents were both competitive triathletes who encouraged physical activity and participation in team sports. Krissy became a personal trainer at 18, expecting it only to be a college job, but soon developed a passion for helping others, and decided to pursue a career in fitness after graduating.

Krissy relocated to Southern California in 2012, where she was exposed to powerlifting and CrossFit, furthering her growth as a coach and athlete. Soon after, in 2013, Krissy overcame her decade-long battle with drug and alcohol addiction. Her newfound sobriety prompted Krissy to put herself in a new, even more challenging environment: New York City. Relocating to New York gave Krissy the opportunity to work with all manner of athletes, including NFL professionals. While living in Manhattan, Krissy wrote and published numerous books on her nutrition philosophies, and created a lifestyle brand, Doughnuts & Deadlifts, that is representative of those philosophies.

Krissy relocated back to Reno in October of 2015 to open Black Iron Gym and launch Black Iron Nutrition. Through Black Iron Gym and Black Iron Nutrition, Krissy hopes to provide the fitness community with an empowering environment where people can learn, and become both mentally and physically stronger.

In September of 2017, Krissy was diagnosed with the auto-immune disorder, Celiac Disease. Krissy is eager to help others with her GI condition achieve gut health through proper nutrition.
