CMP is growing! Meet our New Providers

Our mask policy


As of March 20, 2023, CMP no longer mandates mask-wearing for patients or employees.  However, we do still recommend the wearing of masks to prevent the spread of respiratory diseases while in close indoor settings.


If you have respiratory symptoms, we urge you to consider the health of others around you and wear a mask. If you do not have a mask with you, our staff can provide one.


We also have drive-up respiratory testing available. Call your provider for more information.
