Living Well & Eating Well Fueled by Catalyst 4 Fitness

As a certified personal fitness trainer and nutrition coach, I founded Catalyst 4 Fitness because I enjoy working with others who are passionate about their health and fitness.

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. These are a great value add for other trainers and gym owners.

For gym owners, independent trainers, yoga instructors, and health coaches, 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.

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 fitness 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 either aren’t sure which supplements to take or what to eat afterward, or they are making food and supplement choices that aren’t helping them reach their goals.

I looked at what was available on the market and was dismayed at the absorbability of the supplements, and the nutrition of the protein bars and energy bars. 

I knew I could do better. I launched a supplement line that focuses on bioavailability (absorbability) and then created a meal replacement bar that is nutritionally sound, satisfies your hunger, keeps you full for hours yet low enough in calories for those wanting to lose weight. And it tastes good too! 

I know how important it is to be active and eat well.  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.

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!
