How our team works
One diagnosis, made with ultrasound
Every new problem starts with an exam and, when useful, in-office ultrasound, so the plan is built on what is actually injured.
Physicians and PAs, one plan
Physicians lead each plan and perform procedures. Physician assistants help you get seen sooner, handle follow-ups and shockwave sessions, and keep your rehab on track.
Specialists under one roof
Sports medicine, pain medicine, and rehabilitation expertise work together, so tendon, joint, nerve, and spine problems are treated by one team.
