Learn More About MMA

As a growing practice comprised of physicians and certified registered nurse anesthetists (CRNAs), Midwest Anesthesia Associates strives to remain independent. We think that having the ability to make local decisions results in better outcomes for our patients and a more enriching environment for our professionals, and it fosters personal accountability that benefits the healthcare industry as a whole.

Why Patients Choose USAP-Indiana

Our emphasis is on caring for YOU. That’s why we work just as hard to find the right medical professionals as you do. USAP-Indiana has assembled a first class team of northeast Indiana’s most trusted physicians and certified registered nurse anesthetists (CRNAs) to offer comprehensive anesthesia services.

Our Purpose

We can trace our roots back to 1947 when two local physicians, Dr. Hamilton and Dr. Havens established a practice to provide anesthesia services. We incorporated in 1978, and we’ve been on the move ever since. Even after all these years, our purpose remains the same:


To provide quality medical care—care, not just services—that results in satisfied patients.


To foster a collaborative environment which attracts skilled professionals who are also great people.


To deliver top-notch, hassle-free service to the facilities where we work.
