The Team
Marc and Marielle Pitts
Owner & Founder
Marc and Marielle met….and then “went out” (were “steady?” “Rizz?” I don’t even know what it’s called these days) way back in middle school. After a tragic dumping (Marielle “just wanted to be friends”) they were able to focus on what they loved- anything athletic. Marc competitively played baseball and soccer and Marielle track, volleyball and basketball. Marielle’s senior year she qualified for states in track. Marc “just so happened” to go to that meet and that middle school spark ignited again. They dated throughout college and were married the summer of Marielle’s graduating year. Although competitive sports started to get further into the rearview mirror their passion for health and fitness did not. Marielle became a registered nurse and then a nurse practitioner and Marc worked his way into training and coaching others. After Marc had been coaching and training kids, teens, sports teams and adults for 10+ years he asked Marielle, “What if we bought the gym I am working at?” The owners at the time had started to discuss the option with him and in 2018, Marc and Marielle bought CrossFit Never Doubt. A vision started to formulate of creating a place where they would prescribe health and fitness over the course of one’s life (RxFitness and Health). Instead of just prescribing exercise, they started to talk about how the clients are sleeping, what their stress levels are, how they are moving (even outside of the gym) and what their nutrition looked like. Add in Marielle’s study of functional medicine (getting to the root cause of medical issues) and RxFitness and Health was born! When outside of the gym, Marc and Marielle spend their time playing zone defense getting their 3 kids to their sports and arts activities.
Amanda Zacchilli
Coach
Always an avid runner, Amanda came the Never Doubt looking for something different. Always the competitor, not just with others but with herself, she embraced the group classes as a place “to toss out energy and clear the mind.” The fun and variety of the movement patterns continued to challenge her, feeding her desire for continual improvement. Three years into being a part of Never Doubt as a member her urge to help others improve and grow kept tugging at her. She began to study on her own and in 2021 she joined the staff as a coach. She currently runs the kids program, coaches adult classes and works individually with clients on mobility with the goal of helping awesome people live healthier, happier and higher quality lives! When not spending time in the gym you will find her immersed in family life with her husband and two kids.
John Iannitelli
Coach
John raced sprint cars for 10 years, swam competitively at a national level, and played 4 years of semi pro football. Clearly, fitness has always been in his blood. After years spent in the gym, John moved into passing along his love of fitness to others. He really enjoys seeing the athletes he coaches succeed after working hard to achieve new athletic goals. He is married to his high school sweetheart and has two daughters. When he’s not in the gym, he enjoys golfing, skating, skiing, and playing football.
Jess Tucker
Coach
After having her third child Jess wanted to find a fitness program that she could stick with. She knew about CrossFit but was pretty intimidated at even the thought of it. After deciding to take the step and walk into Never Doubt she met another mom who was part of the class and that eased the nerves. She hasn’t stopped since. Jess loves the balance of fitness in the gym, exploring the outdoors with her family and helping others reach their nutrition goals. Her favorite CrossFit movements are cleans and burpees. When she’s not in the gym she loves being on the track watching her husband race motocross.
Joanie Mitchell
Coach
Joanie has an athletic background, having participated in everything from kenpo karate to yoga and volleyball over the years. She was tired of her same gym routine and hadn’t been seeing results, so she let her nieces talk her into trying Crossfit. The coaching and variety in workouts were what sold Joanie. After 3+ years of Crossfitting, Joanie is still excited and motivated to learn new things. Joanie has owned a business with her husband for over 30 years and is mother to three daughters. Her favorite PeakFitness class is one with multiple varied movements that hit all body parts and give her a cardio kick. Joanie’s favorite part of coaching is seeing the accomplishment and excitement in athletes when they push past their comfort zone. When she’s not in the gym, Joanie enjoys time with her grandson and sitting on the dock of her lake home.
Sue Bouvier
Coach
After working the front desk at Gold’s Gym for many years, Sue was looking for a new challenge. Her husband at the time had started CrossFit and the curiosity of “why does he go to this place so much” kept roaming in her head. Sue stepped foot in the CrossFit gym herself and, since 2013, hasn’t looked back! Having always had a foot in sports from soccer to gymnastics to cheerleading, she loved the feeling of accomplishing something and the workouts she experienced gave her that same feeling. Being a teacher for the past 18 years, Sue has always had a passion in helping her students finally get a skill or help them see success. That certainly carries over as a coach where she gets to help, teach, correct and encourage athletes to have those “ah ha” moments. When she’s not at the gym or classroom she spends most of her time with her two kids watching them participate in ALL of the sports that they enjoy and spending time with friends at her beach house in Narragansett.
