I had him as my primary care doctor several years ago and my insurance changed and I did not have him on that plan. Not to underate other doctors but he was my favorite doctor of all time. I miss him he was a very friendly and knowleageable doctor.

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.

My wife saw this doctor for over 10 years and was trusted by my wife. However, on 7/6/2018 Dr. Demonteiro prematurely discharged her from the hospital on to have her die two days later with no heart monitor or heart medication. She died with me attempting CPR. I really question this doctor's qualification to practice medecine.

Dr. De Monteiro is one of the very best doctors in the World. I've been his patient for 15 years. He's always genuinely cheerful and deeply caring towards me-always maintains the highest level of medical skills/knowledge. He's an excellent listener, remembers important details from previous visit(s). I'm so very lucky at age 79 to have such a wonderful doctor to rely on for any medical concerns. He's a truly A Good Doctor. His referrals are right on too. Sincerely, Patient, Jane Ann Rager
