Cynthia Brown

Founder / Co-owner / Head Coach

Cynthia Carse Brown is a living example of how a combination of lifestyle, nutrition, and mindset changes can transform your life. In 1997, Cynthia was labeled morbidly obese. A high-stress job, a hectic schedule, and three young children still in diapers, led to a life of emotional and compulsive eating. She had tried various diet fads, programs, and pills only to continue gaining more weight after each attempt. At the end of 1999, Cynthia hit bottom. Tipping the scales at over 300 pounds, she was depressed, frustrated, and desperate. She was fed up and tired of simply existing. She wanted more out of life – for herself and her family.

Cynthia completed a 12 week food and exercise program and her life would never be the same. This accomplishment fueled her passion to learn more about the science behind her success. She realized that it wasn’t diet alone, but the blending of fitness and motivation that helped propel her towards many more successes to come.

Her transformation inspired others and she began delivering small workshops to share the information she had to help others accomplish their goals. She became a certified life coach in 2003 and continues to motivate and inspire everyone around her.

Cynthia is actively involved in the operations and provides programming for Cynergy CrossFit as well as individual clients. She has adapted programs for teens, youth sports teams, seniors, paraplegic and individuals with other disabilities. She continues to coach CrossFit group classes as well as provide life coaching for individuals and groups, develop trainers, and lead nutritional and goal-setting workshops.

She organizes and hosts annual events and has devoted her life to helping others achieve their own personal goals. Her extraordinary blend of knowledge, drive, and encouragement is an inspiration to everyone she meets.

Cynthia also provides personal training, remote coaching and nutritional coaching services. You can contact Cynthia at cynthia@cynergytraining.com.

Level 1 Coach
Cynergy Training Coach since 2025

Growing up, team sports never really resonated with me—I often felt uncoordinated and lacked the passion to pursue them seriously. Instead, I gravitated toward recreational gymnastics, which I enjoyed throughout my childhood. It wasn’t until I met my husband that I was introduced to the world of barbells and functional fitness. In 2014, I stepped into my first CrossFit box, Cynergy, and that’s where my fitness journey truly began.

I’ve been doing CrossFit for about 12 years (in a box or two and from home!), with a few years off in between to focus on raising my family. I’ve been back full-time for the past three years, and it feels amazing to be back in the groove. Coaching has always been something I’ve thought about, and in June of 2025, I earned my CrossFit Level 1 certification and officially stepped into the coaching role.

What I love most about CrossFit is the strong sense of community and the constant positive energy—it’s something truly special. I’m excited to share my passion for the sport and help athletes, whether you’re brand new or a seasoned veteran, continue to grow, challenge yourself, and have fun doing it.

Let’s lift heavy, move well, and support each other every step of the way!

Testimonials

Patty Stewart
Cynergy has changed my life.

The community that I walked into was warm and welcoming. I was intimidated at first but that didn’t last long. I have transformed myself during the last months in large part due to the education, support, information and guidance I’ve received. I push because I’m encouraged and guided to push. I smile because everyone there smiles at me. If you want the experience of a superior motivated hard working community YOU MUST give Cynergy a try. I promise you will be welcomed with the embrace of a talented pool of athletes and coaches alike. 5 stars simply isn’t enough.

Gregory Reed
Cynergy has become a family affair for us.

My wife, my son, and my daughter all participate. Everyone has been so supportive of me and my family and it’s been really fun to experience this together. I truly believe it has brought us closer together as a family. The support my family and I get on a daily basis has been a key factor in my 50 pound weight loss journey over this past year.

This is a place where you will meet great people ... and become a better person both physically and mentally.

Shaun O'Hearn
Everything about this place is top notch.

I suffer from sciatica and the best thing for me is functional movement. I have truly found my perfect match! Honestly I can’t imagine my life going forward without Cynergy Training and all of the wonderful people involved!

Julia Wright
How every gym should be!

Cindy has created something special here these past 14+ years. It’s a great place for beginners, long time athletes and everyone in between. We’re lucky to have this gem so close to home!

I’ve never felt more welcomed.

The few trainers I’ve worked with have been nothing shy of great… And the most impressive was a personal email from the owner of Cynergy when I signed up… That speaks volumes. Thanks again.

Paula Hagerty
A welcoming atmosphere with something for everyone.

I am a 72 y.o. retired nurse and former Marathon runner. buMy daughter talked me into trying it and I must say I am hooked. My three grandsons are Cynergy Kids. It is truly a family affair.
