I enjoy serving the doctors and patients in the Central Texas area. I take pride in working with challenging orthopedic cases involving the spine, shoulder, hips, knees, and ankles using an evidenced based approach supported by research. My forte is identifying and working at restoration of normal joint movements to decrease localized pain, reduce muscle spasms to improve circulation, improve movement impairments, and calm irritable nervous tissue to restore function in the individual patient with one on one customized therapy programs. Often, we can centralize spinal radicular symptoms in patients in order to delay or eliminate the need for surgery. In patients that still require surgery, improved tissue vascularization from exercises typically improve post-operative outcomes. I rely on support from my referring physicians to allow for time to work on the biomechanical dysfunctions that lead to pain and functional deficits.
As a previous sufferer of vertigo myself, I understand the helplessness and fear associated with vertigo dysfunction. Disorientation associated with this mechanical dysfunction is totally debilitating and has known to effect individuals of all ages. I have taken additional coursework on helping others restore normal vestibular function associated with Vertigo and enable them to discontinue the medications primarily used to treat the nausea symptoms.

Michelle had been searching for a career path that would allow her to be active while also sharpening her mind. Fatefully, she suffered an injury as a hurdler on her high school track team, made a recovery after attending physical therapy as a patient herself, and the rest is history. She has also overcome countless other injuries from cross-country and obstacle course racing. She uses these experiences to empathize with patients and to collaborate with them to balance the healing process while finding modifications for the activities they love. Since starting her career at Allied, she has grown to have a love of treating Pelvic Floor in addition to her first love Ortho. She has a passion for treating conditions that society often dismisses or shames; it’s one of her most common soapboxes she’ll happily stand on. She has completed extensive advanced training for addressing pelvic floor conditions for all genders.
