About

Clinical Depth. Academic Rigor. Courtroom-Ready Opinions.

I am a licensed physical therapist with a Doctor of Science degree in rehabilitation sciences and 16 years of clinical experience spanning outpatient orthopedics, acute care, and musculoskeletal specialty practice. My clinical background is grounded in differential diagnosis, evidence-based intervention, and defensible documentation — the same competencies that underpin effective expert testimony.

Since 2024, I have served as an Assistant Professor of Practice in the Doctor of Physical Therapy program at the University of Arizona, where I teach clinical reasoning, musculoskeletal examination, and CAPTE-aligned curriculum design. This academic role keeps me current with evolving practice standards and the professional expectations against which clinician conduct is measured.

I work with plaintiff and defense counsel on cases where the standard of care for physical therapy is at issue. My opinions are grounded in published evidence, applicable guidelines, and professional norms — not advocacy.
