Jennifer Bryson

I was born in Greensburg, Pennsylvania.  My family moved “South” to Aiken, South Carolina when I was 15.   I graduated from Clemson University with a degree in Microbiology and went on to the Medical University of South Carolina to pursue my dreams of becoming a Physician Assistant.

Upon Graduation from MUSC, I moved to Charlotte and took my first job working as an Orthopedic PA.  My job responsibilities included diagnosing and treating minor orthopedic injuries as well as assisting in the operating room performing total joint replacements.  I eventually left orthopedics to pursue a job in Internal Medicine.  My interests were preventive medicine and wellness education with a primary emphasis and focus on diabetes education. About a year after the birth of my first son, I left Internal Medicine to work for Presbyterian Urgent Care.  After years of focusing all of my energy on school and my career, I realized that I was neglecting many of the things that I was encouraging my patients to do.  I was struggling with my workouts and with my weight.  I was 35 pounds heavier than I am today!   I did not know how to incorporate exercise into my busy life.  I joined the YMCA and shortly thereafter was introduced to Denise Duffy.  I began running and weight training and have not looked back since!   SmartCore helped transform the quality of my life through structured work outs and the encouragement of active participation in regular fitness activities.   I decided that I wanted to help others in their fitness journey.  So I got my personal training certification!

As a personal trainer and Physician Assistant, I want to share my enthusiasm for fitness, encourage a happier and healthier lifestyle, and help you realize and reach your potential.   I believe that with the right training program such as SmartCore, a bit of determination and support, anyone can achieve their goals.   I hope to create an environment that not only motivates but empowers my clients to continually challenge themselves.   My dream would be to incorporate a medical wellness component to fitness someday.   

Oh yes, last but not least….In my spare time, I enjoy running, biking, and hiking.  I have two boys that keep me constantly on the go! We love the beach and the WWC!   I have participated in several half marathons and a sprint triathlon.   I have been working out with Denise for over 15 years!  I look forward to seeing you in the gym soon!


Dr. Casey Lee Schneible

Dr. Casey Lee Schneible is originally from the town of North Syracuse, New York. He grew up living in Central New York his whole life and loves the beautiful change of seasons that New York promises every year. In school, he played football and tennis. He also played basketball with the Catholic Youth Organization (CYO) through his church.

Furthering his passion for creativity and his skill for working with his hands, Dr. Casey would help his father with building things and remodeling homes. Growing up with a father who was a business owner, Dr. Casey learned a lot about what hard work ethic was and from a young age knew that he wanted to help people.

After a high school project requiring students to look at different career possibilities, Dr. Casey discovered chiropractic. Gaining the opportunity to shadow a local doctor, Dr. Casey knew that chiropractic was what made sense to the passions in his heart. Learning that he could use his hands to “fix the body” (chiropractic, in Greek, literally means practice with the hands) welcomed him to a profession worth pursuing.

Exploring the possibility of studying away from home but remaining in New York is what led Dr. Casey to the University at Albany in 2008. There, he stayed very active playing intramural football, basketball, and softball while focusing on his studies of the human body and anthropology. Four years later, Dr. Casey obtained his Bachelor of Science in Human Biology, graduating with honors, summa cum laude. Upon graduating from Albany in 2012, Dr. Casey studied at New York Chiropractic College located in Seneca Falls, New York. He loved the charm of this small town, beautifully nestled in the region of the Finger Lakes. He takes pride in the fact that he attended this top school and appreciates its factual and evidence-based approach to chiropractic.

Dr. Casey’s love for traveling and adventure led him to Charlotte after graduating with his Doctor of Chiropractic degree in 2015. He appreciates Charlotte’s weather and its centrality to the mountains and the beach. He also likes the economy of the city and how it is filled with younger, growing families. Dr. Casey currently works with Keith Clinic as part of their Chiropractic Team. Dr. Casey is the treating team Sports Chiropractor for the Charlotte Checkers and his team is also the Official Chiropractors for the Charlotte Hornets. 

Dr. Casey lives by the motto, “Movement is life.” He notes that teaching people about biomechanics, proper posture and movement patterns helps improve their quality of life. He emphasizes that staying active does not have to be complicated. “Find those areas that are not moving properly and put motion there. It’s as simple as that.” When it comes to nutrition, Dr. Casey has personally experienced the benefit of food prepping, which allows him to plan out his meals, nutritionally and in correct portions. He encourages the same for his patients and even says that you…” don’t have to be strict all the time. Take a few days to learn the difference between what is a good bread to eat and a not so good bread to eat…or what the difference is between a good carbohydrate versus a bad carbohydrate is…It really can go a long way in your health.”

In his free time Dr. Casey loves to stay active. To maintain his lifestyle of health, Dr. Casey works out and plays a lot of sports like basketball, football, volleyball and tennis. He really enjoys outdoor activities and hiking the mountains. Though his team is the New York Giants, Dr. Casey isn’t ashamed to follow his favorite players from team to team. He loves to watch athletes perform at their best and for any game he watches to be competitive. He likes living in Charlotte because there is always something to do and because it makes going back home to visit friends and family better every time.
