How likely are you to recommend Dr. Demonteiro?

(Select your rating)
Dr. DeMonteiro was our primary care physician for many, many years until we moved out of state. I don’t know if we’ll ever find a doctor as caring, trustworthy, dedicated, and willing to do whatever it takes to ensure that we are well taken care of. We were confident that if we had an illness or condition to treat, he would address our concerns. He was always willing to run the necessary tests, rule out life-threatening illnesses early, prescribe necessary medications, apply or recommend viable solutions, answer questions, explain his reasoning, describe pros and cons, provide much-appreciated coaching and refer us to high-quality specialists to get us needed care so we were as healthy as we could be. Yes, there might be a bit of a wait in the office on occasion, but for the sake of good health, a few minutes in the office is a small price to pay. His PAs are top notch, too, if you’re unable to wait. He is a true, rare gem. I recommend Dr. DeMonteiro without hesitation.
