Who we are

Michelle Powell founded MASA in 2010 to solve the shortage of skilled assistants in the surgical suite. Our surgical assistants have filled this gap for over 5,000 surgeries in over 10 different facilities in the St. Louis area.

Our team of 15 surgical assistants is very experienced across a wide variety of specialties, including robotics. We coordinate staffing needs on a daily basis through the facilities operating room director.

With the shortage of skilled help in the surgical suite, having an outside source you can count on can be invaluable in keeping your operating room running efficiently.

Our Mission

To enhance surgical room efficiency in St. Louis-area facilities through excellent surgical staffing.
