Kelsie Mazur PT, DPT
Born and raised on Chicago’s Southside, Kelsie is a distinguished Doctor of Physical Therapy, bringing a wealth of experience and passion to Wattage’s Physical Therapy clinic. With an athletic background as a competitive gymnast and collegiate cheerleader, Kelsie has always been deeply invested in fitness and the mechanics of the human body. Her journey into physical therapy was inspired by personal experiences—navigating her own rehabilitation from a significant neck injury during college and witnessing her own father’s recovery with the help of physical therapy after a severe accident. These events fueled her determination to pursue a career where she could make a meaningful impact on individuals’ lives. Kelsie holds a doctorate degree in physical therapy and a Master’s in Kinesiology, complementing her extensive clinical experience gained across various settings before joining Wattage. Known for her patient-centered approach, Kelsie emphasizes the importance of improving quality of life beyond the conventional business model, aiming to deliver compassionate and personalized care for all. Her life mission is to empower her patients, helping them achieve their health and fitness goals through a blend of expert knowledge and genuine care. Whether it’s a nagging injury, pelvic floor issues, vestibular, or neurological injuries through persistence and consistency, Kelsie loves helping people achieve things they didn’t think they were capable of and treat the whole-person to optimize movement.
When she’s not treating her patients, you can find Kelsie grinding through a CrossFit Metcon, hanging out with her identical twin sister Karlie, listening to Morgan Wallen or Tay Tay Swift, and watching anything on Bravo.

Calvin Thai
Born and raised in Houston, Texas, Calvin Thai is a Doctor of Physical Therapy who brings both athletic experience and a deeply patient-centered philosophy to his clinical practice. After moving to Chicago in April 2024, Calvin continues to pursue his passion for helping individuals better understand their bodies and take ownership of their health. With a background as a competitive tennis player in high school and a collegiate volleyball athlete, fitness and movement have always been central to his life.
Calvin’s journey into physical therapy was shaped by personal experience. After enduring multiple shoulder injuries and ultimately surgery, he was introduced firsthand to the impact that skilled physical therapy can have—not just in recovery, but in restoring confidence and long-term performance. This experience, paired with his lifelong involvement in sports, sparked his decision to pursue a career in physical therapy.
He earned his Bachelor’s degree in Hospitality before completing his Doctor of Physical Therapy degree at Baylor University, a path that uniquely shaped his approach to care. Calvin places a strong emphasis on patient education and empowerment, believing that long-term success comes from equipping patients with the tools and understanding needed to manage their conditions independently—not just resolving symptoms in the moment. Known for his thoughtful, collaborative approach, he strives to help patients feel confident, informed, and capable throughout their rehabilitation journey.
When he’s not in the clinic, Calvin enjoys hosting café pop-ups, playing volleyball, and spending time with his fiancé and two cats. Whether working with athletes or individuals navigating everyday aches and injuries, his goal is to help patients return to the activities they love while building resilience and confidence in their bodies for the long term.
