David Nash, Owner
Lead Trainer, Lead Nutritionist
Hi everyone, Welcome to Pinnacle Fitness Center. My name is David Nash and I am the founder and owner of Pinnacle Fitness Center. I am a native of Atlanta, and I love to assist people in reaching their fitness goals. I started my journey as a health and fitness expert in my early college years.
In 2000, I joined the Army Reserves, and served in 427th Medical Logistics Battalion as a medical supply specialist. Our unit was deployed to Afghanistan from 2003-2004 and our warehouse provided medical supplies for the front line medics and Bagram Hospital. Soon after our deployment, I met my wife Faith in 2004 at Kennesaw State University.


In 2001, I became a certified personal trainer & furthered my education earning a degree in Health & Physical Education from Kennesaw State University.
After years of successful training I decided to fulfill my vision by opening Pinnacle Fitness Center, Decatur in March of 2008.
Since our inception we’ve pushed to lead from the front. I have picked up multiple certifications in fitness, stretch therapy and nutrition. I have also competed in natural bodybuilding shows.
I have experience in helping individuals from all walks of life transform their bodies and improve their lifestyle. I’ve also written for a variety of publications and have spoken on various health related topics.
Each one of our staff members have been trained under my guidance and has the credentials to help you on your journey.
When I’m not at work I spend quality time with my wife and 4 children.
