We Love Pets

PMAH is a family owned, state of the art full-service veterinary hospital focused on providing exceptional care to the animals in the communities of Acton, Concord, Maynard, Sudbury, Stow, and surrounding towns. Our practice is made up of highly talented veterinary professionals who are passionate about animals and will take care of each pet as if it were their own. 


The PMAH founders started this hospital with a goal to improve the status quo of quality care for animals as well as the full client experience that pet owners demand for their loving pet.
