    Melissa grew up in Michigan but has also lived in Missouri, Illinois and Virginia. She is a graduate of George Mason University (GMU) where she studied Exercise Science and Business. At GMU Melissa was a two-sport athlete in Volleyball and Track & Field.  During her four years at GMU she researched injury correlation to gender and sport, as well as how to reduce specific injury rates through proper training and instruction.

    She currently competes in CrossFit and Olympic Weightlifting, and has competed nationally in weightlifting since 2010, holding several records in the Maryland & Potomac Valley area and has finished as high as 5th at the USA Weightlifting National Championships.

    Previously, she was general manager at BREAKAWAY Fitness and Sport in Virginia. While working as the general manager she also trained all types of individuals and athletes – injury clients, elderly population, and athletes from an array of sports including high-school athletes, Olympic weightlifters, CrossFit athletes and athletes at the collegiate level (working with athletes from every sport at Georgetown University).

    After visiting her family in Tucson she quickly grew to love it and decided to take the leap across the country where she can enjoy the sun and wonderful people while she helps others change their lives through healthy choices, fitness, education and a new way to look at health care.

    She joined Rejuv Medical Southwest in March of 2014 to head up the Medical Fitness division of the company as Medical Fitness Director and Head Personal Trainer.

     In January of 2015, Melissa and Matt decided to follow their dreams and open a gym of their own. “I have always wanted to really help people, inspire them and encourage them to make changes in their life so they can enjoy all life has to offer them and so much more. This is a journey that will last a lifetime and I want to be there to help.” CrossFit 646 is where she found this opportunity. She is very excited to be a gym owner, which will allow her to be a key player in changing the lives of the people who entrust their health to her. .

    When Melissa is not working at CrossFit 646 to change lives, she is training hard as a competitive Olympic Weightlifter, spending time with her husband Matt, and their two dogs Georgia and Kasey. She also loves being outside, cooking, writing, hiking and taking pictures.

    CrossFit Level 1
    Registered Nurse

    Courtney was born and raised in Tucson Arizona. Before starting CrossFit, Courtney had never competed in sports. She worked out and did some yoga as well, but never worked too hard when it came to physical and nutritional endeavors. Her life changed forever when she found CrossFit. She began taking CrossFit classes at 646 and found that she picked up the movements very well, even though she couldn’t back squat the 45 pound bar in the beginning. She took a liking to the Olympic lifts and after some training, she did her first weightlifting competition in 2015 where she went 6 for 6. Since then, Courtney has won a few local competitions and even competed at the 2016 University National Championships! Even though her qualifying total was ranked 38th in the 63 kg weight class, Courtney exceeded expectations by finishing 7th at University Nationals and 5th for the Under 25 National Championships and her total of 165kg qualified her for the 2016 American Open! Courtney is looking forward to helping other people meet their fitness and health goals as she has done. Courtney truly is living proof that every person can meet their goals with consistency, determination and a little fun! In addition to coaching, and working out every day, Courtney is also a full time Nurse in Tucson.

Rachel-Carramusa

  • Rachel Carramusa

    Bachelor of Science in Physiology - University of Arizona (in progress)
    CrossFit Level 1
    CPR/AED

    Rachel was born in northern California and moved to Arizona with her parents in 2001. Rachel began soccer at the age of 6 in California and played competitively when she moved to Tucson for Tucson Soccer Academy and Rush Soccer Academy until she graduated high school from Catalina Foothills. In her last years of competitive soccer, Rachel had to get shoulder surgery twice causing her to have to take time away from the sport she loved. After starting her undergraduate schooling at the University of Arizona, as a proud Wildcat, she soon found herself bored and extremely out of shape and none of the intramural activities on campus caught her eye. Then one of her friends brought her to 646 to try out a class. She fell in love with the friendly competitiveness that CrossFit entailed and jumped right into it. In the midst of her start at 646, Rachel realized it was time to focus on her health and nutrition and lost over 25 pounds in just a few months. She saw how CrossFit had changed her life physically as well as mentally and loved everything about it. Rachel began interning and coaching at CrossFit 646 because she wanted to help give others the opportunity to learn to love CrossFit and believe in the methods of community based functional fitness as well. Rachel is currently finishing up her last credits at the University of Arizona to receive a Bachelor’s of Science in Physiology.

After two months of personal training, she participated in her very first CrossFit class; a moment Nikki references as “life changing”. Her enthusiasm for the Sport of Fitness, along with her instructing experience caught the eye of Matt and Mel, who suggested she pursue a CrossFit Trainer Certificate and instructing at 646. Nikki loves CrossFit because it’s allowed her to discover capabilities she never knew she had. She loves the friendly competition, the community, and most of all the excitement of finishing a really tough workout.

This opportune time was the beginning of his exciting and challenging relationship with CrossFit. Immediately he enjoyed the gymnastic and Olympic lifting aspects of CrossFit and only recently has learned to love the cardio aspect. He believes CrossFit is not only an effective and fun way to train but also an avenue for friendships that will last a lifetime.

  • Samantha Mowbray (intern)

    Sam is a Learning Specialist with Intuit. Her daily focus is on coaching and developing facilitators around the world to perfect their craft and deliver the best possible experience to those who support Intuit customers. Sam tried her first Crossfit class in late 2015, but didn’t commit daily until June 2016 while traveling for work and visiting various boxes around the US. A coach once quoted James Fitzgerald, “There are few places on earth where we are asked to make that very real connection with our body and our spirit. CrossFit is one of those places. Dig deep, don’t quit, and discover why you are here.” This message inspired and drove a focus inside her. Her passion for Crossfit comes from seeing people improve every day. It’s so exciting to see someone do something they couldn’t do yesterday. Combining a love of Crossfit and a love to see others grow… Sam is driven to fulfil a dream of coaching. Sam tries to remind anyone she speaks with to not compare yourself to others. Everyone has their own strengths and weaknesses. Spend time improving both and enjoy the journey.
