Meet Momenta

Thanks to the success of our treatments, the dedication of our providers and the loyalty of our patients, Piperis Interventional Pain Care grew exponentially over the past nine years; so much so that we added a new physician to accommodate our growing patient base. In that time, we also realized that a new name was in order – something that speaks to our services and our mission. We chose Momenta Pain Care.

Simple and meaningful, Momenta is the plural form of “momentum,” a word that entails moving forward and gaining energy. It brings to mind encouragement, health and a series of steps in a positive direction. When you choose to work with Momenta, you’ll gain the energy and positive outlook that comes with being pain free.

We’re excited about this change, and we’re looking forward to continuing to serve you in the years ahead, delivering the expert pain care and advanced therapies you need to feel better and move forward.
