    "I believe that good physical therapy is one of the most powerful tools in the medical field - as the biomechanical experts we bring a level of unmatched understanding and perspective to injuries, pain or performance issues. We bridge orthopedic medicine with physical activity in a way that is truly amazing."

    My gift and passion as a physical therapist is seeing patterns and dysfunction that others often miss—and clearly explaining the “why” behind your pain. I’m committed to empowering you to become resilient, strong, and confident in your body so you can take on all that life has to offer.

    As a woman, to other women - our bodies change so many times throughout our life - from puberty, to pregnancy, to perimenopause. My love and expertise is to help you continue to feel like you, and perform like you, during any stage of life.

    PT, DPT, CSCS

    I value blending a sharp eye for biomechanics, a deep understanding of anatomy, and strong clinical expertise to uncover the true root of orthopedic and running-related injuries. I pair that precision with genuine connection, clear communication, and positive energy so every patient at Aretas feels understood, empowered, and equipped for lifelong recovery, performance, and lasting physical resilience.

    To me, physical therapy is about empowerment and education; I strive to instill control and confidence in their recovery or performance. I focus on understanding, education, and high-quality movement so my patients can move, perform, and live better - not just temporarily, but for life.

    I love blending the science and art of physical therapy, especially the personal connections that can genuinely change someone’s everyday life. I’m driven to uncover the true root cause of your injury so you can clearly understand what’s happening and move forward with confidence.
