About Me

My Story

 WHY Marissa's Fit Boutique you ask...?

It all began my freshmen year in college when I landed my first personal training and group exercise job at a local gym. I was intimidated, nervous but super eager to apply what I had learned in Health and Fitness Vocational School.

My very first class was called MegaMotion (you may laugh), I choreographed it and created it from scratch. I remember standing in front of 6 women who paid for a “MEGA” workout… knowing very little about instructing. I let my enthusiasm shine and jumped into it anyway.

Looking back, this would be the foreshadowing of the next few years of my life.

After that, I went on to personal train at other gyms and created more classes with amusing names including SandSLAM (workouts using sand bags) and IRONhour (informative weight lifting class, hosted in the weight room, aka “man cave” {exaggerated eye roll} at our Universities Rec Center)

As the co- founder of IRON babes LLC, an online training business my best friend and I created in college, I would NEVER EVER call a weight room a man cave!

The weight room became my home away from home. I competed in 4 NPC Bikini shows and a powerlifting competition while going to college. All the fat loss, fat gain, muscle gain, show dieting, post-show dieting, training on 800 calories, training on 2000 calories etc.… gave me experience, knowledge and lead me to some of best mentors.

After college, “real life” (I hate that phrase) kicked in and my college debt pressured me to get yet another, personal training job but this time I would be referred to as a “Fitness Specialist” (fancy, I know).


I loved what I did, the people I helped and the employees I worked with but my spirit wasn’t fulfilled. I knew in my bones the cap off pay, cookie cutter “employee” life was not for me and I was 100% settling.

I told myself over and over “If was an owner, I am 100% confident I could do it better.”

That one decision freed my mind of the “what if”, “you can’t”, “too soon”, “not ready” brain molasses that has bogged me down and held me back from going after my God Given Gift.

Since I was 13, I’ve been telling people “Confidence is key to the lock of success.” A phrase I totally made up but I honestly never believed in anything more.
I’m ready to share my gift and I know Marissa’s Fit Boutique is my calling.

I hope you enjoy following my journey from flipping a bare brick building to an uplifting, sparkling (probably pink) training studio.


  • B.S. Exercise Science
  • 7+ years of experience in health & fitness
  • Clients ranged from High School competitive athletes to older active adults.
  • Former sponsored Athlete for Maximum Human Performance supplements
  • Former NPC Bikini Competitor
  • Studied strictly science based long term weight management techniques


Many personal trainers will try to sell you on short term weight loss solutions or programs that do not match your physique goals.  I am MUCH different.

I believe in approaching fitness from a holistic level.  Nutrition, mind, body and spirit are all connected. 

I am committed to using the most updated scientific research to bring the most advanced fitness techniques to your programs.

I seek highly studied nutrition methods to implement into my clients diet recommendations. 

There is a lot of research that goes into calculating proper diet and exercise plans based on blood work, hormones, and genetic predispositions.  

Fortunately, I believe in customizing a well rounded, enjoyable program based on all of those factors previously discussed!
