About Me

Katherine Martin grew up in Atlanta, Georgia. She attended Woodward Academy and was a five-year starter for the Varsity softball team, which included 8th grade. After breaking and setting numerous offensive and defensive records, Woodward Academy retired her jersey her senior year. Her travel ball team, the Atlanta Travelers, earned a berth to nationals the summer before her senior year where they placed 5th in the nation.

Katherine continued her softball prowess by attending the University of North Georgia (UNG) on a softball scholarship. She served as team captain her junior and senior year and made three consecutive trips to the Women’s College World Series. She received numerous accolades, including but not limited to, Female Athlete of the year for the UNG Athletic Department and All-American for the NCAA.

After graduation, Katherine followed her love for softball across the continent to coach in British Columbia, Canada. There, she spent her time coaching various teams and coaches along with giving private lessons. Her fondest moment was when her softball team, Team British Columbia U16, won the gold medal at the North American Indigenous Games and won the John Fletcher Spirit Award, which is given to the team who possesses exemplary character. This marked the first time in history a team at the North American Indigenous Games brought home the most gold medals and the John Fletcher Award.

After returning home from Canada, Katherine spent three years teaching and coaching in Atlanta, Georgia. She prepared student-athletes to compete by training them in her personal fitness classes. She moved to Middle Tennessee in the summer of 2017 to take over as a Wellness Instructor and Head Softball Coach at Battle Ground Academy. During her time there she developed and implemented strength programs for students and student-athletes in classes along with the summer workout program. She was awarded Coach of the Year for the 2019 softball season leading her team to the elite eight. Outside of the classroom and off the field she served on numerous campus committees including but not limited to the Strategic Planning Committee and the Interviewing Committee. She is passionate about health and wellness and has a heart to serve those around her. If she is not in the weight room, you can find her on a local trail or kayaking. She is eager to start this new journey with TOA and is excited to serve the Murfreesboro community.

About Me

Malcolm Manier is a former basketball player from Lebanon, Tennessee. "I’ve played ball for over half of my life, but decided to take another route after injury. Early on in my high school career I started loving working out. I then took up boxing my sophomore year of college and my life changed. My love for fitness grew to passion. I graduated from Georgia State in 2006 with a BA in Psychology and a minor in exercise science. After playing professional basketball, I got my CPT in 2010 from ACE. In 2014, I got my Sports Nutrition certification and TRX certificate. Now I work with four high schools and do Strength and Conditioning for their basketball and baseball teams. To date, I work with 120 athletes on a monthly basis. I'm very thankful for TOA bringing me in to help!"

About Me

Marci Beck, MS, CSCS

Marci is a NSCA (National Strength & Conditioning Association) Certified Strength & Conditioning Specialist (CSCS) with a dual master’s degree in sports science and rehabilitation. She is a former high school multi-sport letterman in both Canada and the United States, and a collegiate basketball athlete. Her lifelong athletic affiliation drove her to becoming a NASM (National Academy of Sports Medicine) certified personal trainer, which later transitioned into her CSCS certification. Marci founded and operated a private sports performance and fitness facility in Detroit, MI, working with athletes from high school and collegiate sports to retired professional athletes and general population clients.

Her approach for both athletes and general population is holistic in nature, operating under the principles of sound mechanics and the highest possible movement quality. She believes the whole person needs to be progressed for optimal and sustainable results. After launching her facility, Marci had the opportunity to move into the collegiate arena where she completed internships at Middle Tennessee State and Vanderbilt University, working with football, basketball, and all Olympic sports programs including soccer, volleyball, golf, tennis, swimming, track (sprints & throws), lacrosse, and cross country. She later assumed the role of strength and conditioning coach for women’s soccer and softball while assisting with football at Northwestern State University. Due to her interdisciplinary experience, Marci also assumed the role of return to play strength coach, working most closely with football and athletes from across the Olympic spectrum.

Marci believes in a multimodal and vertically integrated program that provides the proper dosage of each element of performance. She makes sure to incorporate movement diversity as a significant consideration to prevent and mitigate potential chronic injury and acute injury regression. Her athletes and clients will experience an innovative program that incorporates things like functional range conditioning, Pilates, and yoga to ensure all angles of movement are tested and progressed. Her goal is to create an environment where people can learn to push beyond thresholds to gain a new perspective of their true abilities. She believes this is done by building a specifically tailored program for each athlete and client that provides a STRESS accompanied by the right RECOVERY to gain the desired ADAPTATION.
