Living Well & Eating Well Fueled by Catalyst 4 Fitness

I founded Catalyst 4 Fitness because as a nutrition and fitness coach, I love the fitness industry and enjoy working with passionate entrepreneurs, business owners, managers, and members concerned about health and fitness.

For gym owners, independent trainers, yoga instructors, health coaches, or franchisees, I created Fit Biz in a Box to fuel your potential to generate revenue and create a better lifestyle for you and your families. Do you want to start or grow a fitness-related business, have no idea where to begin, or need new, fresh ideas? Good news! You’ve come to the right place.

I created high-quality supplements and Catalyst Bars to help health-conscious consumers fuel their bodies with nutrition that far exceeds the run-of-the-mill supplement or ordinary protein bar. Our products are great as an upsell for gym owners, too!

My Journey

During my 20 years in the corporate world, my days consisted of meetings, phone calls, and being on call 24/7. I didn’t have time for healthy, balanced meals. I would wake early to work out at 5 a.m. before work started and be in bed at 9:30 p.m., and would meal-prep on weekends.

Deciding I wanted to focus on my health and wellness and help others do the same, in 2012, I jumped into the health and fitness world by becoming a certified personal trainer and nutrition coach and opening a fitness studio. 

Since then, I’ve successfully helped hundreds of women and men get healthier, lose weight, feel better, and like what they see in the mirror. I listen to their daily struggles about trying to eat better while balancing the demands of life, not having time to make healthy meals, and cringing at fast-food drive-thru windows. If they somehow make it to the gym, they aren’t sure which supplements to take or what to eat afterward!

I looked at what was available on the market and was dismayed at the absorbability of the supplements. The protein bars, energy bars, and snack bars all lacked proper nutrition, and an hour after you ate them, you were hungry again.

I knew I could do better. I launched a supplement line that focuses on bioavailability (absorbability) and then created a meal replacement bar for buy people that is nutritionally sound, satisfying to keep you full for hours yet low enough in calories for those who want to lose weight, and it tastes good too! 

In 2021, I was a quarterfinalist in the international Ms. Health and Fitness contest sponsored by Muscle & Fitness Hers, putting me in the top 1% of all competitors. I know how important it is to be active and eat well.

As the owner of Catalyst 4 Fitness, I have years of both fitness and business-related experience so I can help you make your business and your body fit!
