Chris Knight

General Manager


I grew up in Youngstown, Ohio where I attended college and worked in the hospitality industry throughout. After 2 years of managing the fitness, recreation, and aquatics facilities for a group of country clubs I left the business to pursue a career with the State Police. I completed the process but did not accept a position and instead I moved to the Lowcountry and found Pulseology where I worked my way up into my current role as General Manager. Being involved in fitness through boxing, powerlifting, and bodybuilding I have always preferred to spend my free time at the gym.

Dee John

SGPT Owner/ Group Fitness Coordinator


My Name is Dee John. I am originally from Cape Town, South Africa but have lived in the Lowcountry for the last 23 years. My love for fitness and nutrition started at a young age. My career in fitness began as a Certified Tennis Professional at the age of 16 which inspired me to eventually become a full-time trainer for the last 5 years. I am a certified Personal Trainer, Group Trainer, and Nutritionist. As owner and head trainer of SGPT, I am able to share my passion and help others achieve their goals.

Fitness Director / Personal Trainer / ETC Instructor

  • Exercise Science Degree
  • ACSM Certification
  • CPR/AED Certified


I am originally from Northern Virginia where I worked at Gold’s Gym for almost 10 years. Prior to that, I attended Coastal Carolina University where I received a degree in Exercise Science and fell in love with the idea of someday living near the beach. I enjoy working out and staying in shape, but my favorite activities are playing sports and being active with my dog. My mission is to motivate our members to work hard towards achieving their fitness goals as well as educate them to do so efficiently.


John Duberley

Personal Trainer


I am from Phenix City, Alabama. I joined the U.S. Navy after high school and enjoyed traveling the world while obtaining my electrical mechanical engineering degree. I was the command fitness leader during my time in the Navy, which helped me develop skills to keep 1,800 soldiers in military shape. Now I enjoy focusing on personal goals whether it is to lose fat, get stronger, or run your first 5K. For my biggest passion, I work with youth runners, swimmers, and triathletes, to get them opportunities I did not have growing up. I started a local run club as another way to get the community together for a healthy and fun time!

Brooke M

Personal Trainer / SGPT Trainer


I grew up in the Lowcountry but didn’t get excited about fitness until college in Chapel Hill, NC. Two marathons, multiple shorter races, and thousands of group fitness classes later, I decided to become certified to teach Spinning, later adding multiple Les Mills certifications and a Personal Training certification from NASM. I love the energy in group fitness classes, and get so excited to help participants use the camaraderie and healthy competition of group exercise to accomplish even more than they might on their own! I currently teach BodyPump, cycling, and HIIT Strength at PULSEology. Come join me!
