Front Desk Receptionist
Kiana L.
Location: Tempe
Where You Are From: Born in Page, AZ. Raised in Las Vegas, NV
Outside of work, I'm all about pushing my limits-whether it's hitting the trails for a run, diving into the intensity of MMA, or leveling up my strength with weightlifting.
Trail running challenges my endurance while giving me a deep sense of freedom and connection with nature, allowing me to clear my mind and stay focused. MMA, on the other hand, helps me embrace both mental and physical toughness. The discipline and strategy involved in training and competing keep me constantly evolving, pushing me to be stronger, faster, and more resilient. I'm also an avid reader, always seeking new knowledge, and my faith in Jesus Christ provides a strong foundation that keeps me grounded and inspired. Additionally, I love volunteering at my church, where I can give back to the community and strengthen my sense of purpose. I'm also committed to furthering my education, always looking for opportunities to learn and grow both personally and professionally.
What I Love About My Job at Axis Spine and Sport: What excites me most about working at Axis is the incredible opportunity to witness firsthand the transformation in each patient's health and well-being. Every day, I'm amazed by the positive impact our team has in helping people overcome pain and unlock their full potential. It's truly a privilege to be part of a team that not only improves lives but empowers patients to achieve their best health. Every moment spent here reminds me of the profound difference we make in others' lives, and I'm deeply honored to be part of that journey.
