A native of Arizona, Nicks interests in health + performance stem from his own experiences, playing sports and then going through and rehabilitating a back injury. Nick attended Arizona State University, receiving a B.S. in Kinesiology (Exercise Science) and a B.S. in Biology with an emphasis in history and neuroscience. While in school, Nick completed internships at Fischer Sports Physical Therapy & Conditioning as well as The Neuro Institute, where he worked with a broad range of clientele from Sports Performance to rehabilitation programs for TBI's and Spinal Cord injuries. This gave him both a lot of respect for the human body and also insight into the potential the human body has to come back and perform. Upon graduating in 2013, he opened up After it Training, a training facility that advocates for community, quality movement, and everyday human performance.
Nick strives to train for performance in both body and mind. To be able to function daily and work at your greatest capacity is a huge asset and that's what training should be about, whether you're playing a sport or you have a 9-5

Carrie Markham - Personal Trainer, Pitching Coach, TribeFit Trainer
BS Sports Management – Belmont Abbey College
MS Leadership and Organizational Change – Pfeiffer University
National Academy Sports Medicine (NASM) – Certified Personal Trainer
Carrie Markham is a 5th generation Phoenician who decided upon high school graduation to accept a two sport collegiate athletics scholarship in Charlotte, NC. Upon graduation from Belmont Abbey College in 2009 with a BS in Sports Management, she continued her education at Pfeiffer University receiving a Masters in Leadership and Organizational Change. After receiving her Masters, she stayed in the south another few years working an internship in the NBA and began her softball coaching career. In 2012, Carrie decided to make her trek back across the country to her hometown of Phoenix where her love for softball led her to start her own softball pitching coach career which transformed to personal training. After spending countless hours with female athletes who struggled to perform specific motions with their pitching form, Carrie became more interested in biomechanics and focusing on the differences in the male vs female bodies. Her experience in working with softball pitchers has not only tested her patience but grown her knowledge in the way the body moves naturally and efficiently. Increasing body strength and flexibility is the key to softball pitchers success, and I believe it is just as pertinent to the aver women’s body. Efficiently structured workouts by Carrie will not only help you reach your fitness goals, but will help you manage your personal obligations while taking care of your own health needs.

Katie Rapkoch - PT Assistant, Personal Trainer, TribeFit Trainer, Registered Yoga Teacher
AS Physical Therapist Assistant - Bay State College
NASM CPT - National Academy of Sports Medicine
RYT200 - Aimfree Yoga Teacher Training
As a practicing Physical Therapist Assistant for over seven years, Katie decided to branch out into the fitness world in order to address some of the issues that she feels are all too common in the general population. In the past, many of Katie’s clients have demonstrated limited insight into the importance of health and wellness, both physically and emotionally. Katie hopes to bring awareness to the benefits of physical fitness on one’s emotional well-being.
Katie’s fitness journey began six years ago when she began training for a half marathon. While Katie reached her goal, and has since finished many road races, the repetition of distance running took a toll on her body. Katie has since found that a combination of weightlifting, yoga, and hiking are much more beneficial for her body. Katie believes that balance is the key to all things, and she strives to bring balance into her clients’ lives with a combination of functional movement training and yoga. As a Certified Personal Trainer, Register Yoga Teacher, and with her background in Physical Therapy, Katie is driven to educate and motivate her clients to see the power of mindfulness in movement.
