I am a board-certified physician assistant with over 27 years of experience in both clinical and surgical settings.
I began working with Dr. Stewart in 2005 and have been his primary surgical assistant for most of that time. I am known for a patient-first approach and specialize in assisting in hip and knee arthroplasty, arthroscopic surgery and fracture management.
In 2015, I underwent specialized training in ultrasound guided hip injections. The injections are done for diagnostic and therapeutic purposes. They are done in the office, which is both efficient and cost effective. I administer hundreds of these injections per year.
Outside of work, I enjoy spending time with my wife and four children.
Miranda Madrid

I've been with Chippewa Valley Orthopedics since 2014. During that time, I have enjoyed supporting Dr. Stewart, patients and other healthcare providers by helping to ensure quality care while assisting with clinical and administrative responsibilities. I am committed to professionalism, teamwork and continuous learning. I take pride in making a positive difference in the lives of those I serve every day.

As a Medical Assistant with Chippewa Valley Orthopedics for the past six years, I work closely alongside our orthopedic surgery team to ensure seamless, compassionate care.
From preparing detailed charts and clinical scribing to assisting directly in the OR, I thrive on the dynamic nature of orthopedic medicine. Above all, I am dedicated to delivering a smooth, reassuring clinic experience and helping every patient navigate their journey back to mobility.

I joined Chippewa Valley Orthopedics in 2025 as a medical assistant and have enjoyed being part of such a compassionate team.
I am committed to helping patients feel welcomed, comfortable, and supported from the moment they arrive. I strive to make each visit a positive experience, and I believe even small acts of kindness and a genuine smile can make a meaningful difference in someone's healthcare journey.
One of the most rewarding parts of my role is helping patients on their path to healing and back to the activities they love. Supporting them through that process is incredibly meaningful to me.
Outside of work, I enjoy spending time with my family, staying active, and being outdoors.
