About Me

Hi, my name is Marissa. It all began my freshmen year in college (2011) 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)

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. It gave me experience, knowledge and led 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 haven honestly never believed in anything more.
I’m ready to share my gift and I know Marissa’s Fit Boutique LLC is my calling.

What to Expect

Each training session is very customized to the clients specific goals and needs. I do not create a program until I have met with the client. The client can expect to be challenged and educated throughout the process.

Client Success Story

"Where do I begin. I came across Marissa's Fit Boutique LLC from working with Marissa. I was at a point in life where I needed to change my lifestyle, and I just wasn’t sure how to go about it. I would try to train on my own but nothing worked for me. Marissa was such a great inspiration, she trained like a champion and had the results to show for it. I one day decided to talk to her about some of my goals to get some advice and she informed me about her program. What sold me was that I could eat whatever I want as long as I fit it in with my macro nutrients. Dedication and consistency was what I needed on my part to get the best results.

I’m proud to say that in the end I got the results I worked for. At the end of my six week macro nutrient session I was amazed at how much my body had changed that I signed up for an additional 6 weeks and another 6 weeks after that one. My program was made specifically for me and whatever results I was told I was going to get I got every time. I also liked that within the six weeks the exercises would change after three weeks, just when I was ready to switch things up.

Whenever I had any questions or concerns I was always helped, Marissa would always take the time out of her busy day to make sure I was satisfied, I could tell that this was something she was passionate about. Marissa's Fit Boutique LLC completely changed my lifestyle because of it I am a much healthier and confident about my body. I would highly recommend this program to anyone who wishes to start a successful fitness journey." - Shanice
