Introducing JEM

JEM is a mindset.
It's not waiting til tomorrow or next year or 5 years from now to take control of your life.

My father passed away from brain cancer in 2011. He was 58 years old. When he was diagnosed in 2007 I had just started my career in fitness and I had no idea at that time how much my world was about to change. I was your typical daddy's girl who adored her father and was just starting to enjoy the next phase of our father/daughter relationship - friendship. JEM are the initials that he and I share, his request at my birth. They have always been special to me. So when creating my brand and company I wanted to keep that special bond alive. 

As difficult as it was to lose him at such a young age, it taught me a very valuable lesson. Tomorrow is not always promised. My goal when it comes to my clients is to help them take control of their health. This could include fitness, wellness or accountability. Or all 3. So many people put their loved ones first and their own health takes a toll. This changes now. Together, I can help you live your life. 

What I Do

All of my programs are customized to you.



I offer one on one, duet and semi private personal training sessions. These appointments are offered at my home gym. I work with all types of people with all different types of goals - weight loss, increase strength, functional training, beginners, injury rehab, etc.


The definition of wellness is specific to you and your goals. Whether you want to improve your nutrition, increase your energy, eliminate toxic products in your home or find natural solutions to help any of your health concerns, I am here to support, educate and guide you to better wellness.



Each accountability program is customized to you, your goals and your needs. These programs include fitness, nutrition, and/or wellness. I keep you accountable in a positive, inspiring and uplifting way. Even when you lose your way, I help you find your way back without taking big steps backwards.

About Me


My name is Joan Campbell and I am the owner & founder of JEM. When I think back to my childhood, my fondest memories include sports. I started playing soccer at 5, fell in love with softball at 8 and decided to do competitive cheerleading my freshman year of high school. So when I decided to major in Kinesiology in college, it was just fitting. It came naturally and for the first time I enjoyed learning. I graduated in 2006 and I started my career in fitness the following year after a friend recommended me for a position. Throughout the years I have spent additional hours getting certified in kettlebell, pre/post natal and precision nutrition on top of my CPT from National Academy of Sports Medicine. I have held many positions with the different companies I have worked for: trainer, coach, manager, & regional. However creating my own brand is what I am most excited about. I am also the proud mother of 2 children and a huge supporter of my law enforcement husband. 

I feel so blessed to have found something that I am truly passionate about and love doing. Nothing brings me more joy than watching a client achieve success, overcome challenges and build confidence. This is an amazing life we live and it can be really difficult at times.  No matter what program suits you, I am your partner and we are in this together.
