How likely are you to recommend Dorothy McGrath?

(Select your rating)
Dorothy McGrath has been spot on with everything in taking care of my father. Her knowledge is phenomenal and I would not want him in the care/oversight of anyone else. Her prior cardiac and cardiothoracic experience is indispensable. Dorothy has caught serious medical issues teams of doctors in Boston did not, we truly believe she has saved his life. Dorothy takes the time until the patient understands exactly what is happening and makes sure they feel as comfortable as possible.
