Services
We are dedicated to providing the highest quality of care to our patients with respect and compassion. The relationship between patient and healthcare provider requires mutual cooperation and trust. We are committed to that principle. We ask that you participate in this effort to the best of your ability.
As the practice of medicine become more complex, the process of delivering high quality and coordinated medical care has been severely challenged. Face to face time with physician/provider and access to care have also become compromised. At Diablo Valley Primary Care, we strive to provide you with the care as we would for our family members.
Here at Diablo Valley Primary Care, we are dedicated to providing you with superior and highly coordinated care for your complex and chronic medical problems. Dr De Monteiro is an internist and is an expert in managing complex cases in our geriatric patients. He is knowledgeable about all the specialists in the community and work very closely with them.
Please follow our office policy regarding prescription refills. You may request refills of your medications by either contacting us online through MyJohnMuirHealth or contacting your pharmacy. Requests for refills will be sent via fax from your pharmacist to our fax at 925-687-5091. Please request your refills one week prior to running out of your medications.
Although Dr. De Monteiro is on the medical staff of both John Muir Concord Campus and John Muir Walnut Creek Campus, he admits and cares for our patients only at the Concord Campus. The hospitalists care for all our patients at the Walnut Creek Campus. Once you have registered online as a new user, you can use MyJohnMuirHealth to request your next appointment, get your lab/test results, request prescription refills, or request referrals.

Dr. De Monteiro has a nice practice; however, while conferring with him about given the wrong medication, he would not listen and continued to advise taking the medication. Just a word of advice, always watch out for the side effects of medication (specially Wellbutrin XL) , even when your doctor keeps on telling you it is okay. It was the wrong medication!

Great experience the first time with Dr de Monteiro the second time I was expected to wait over 45 minutes which was a complete pain. They informed me that this was typical and that I should usually expect a 30 to 60 minute delay. Which seems like a joke so when I mentioned to then that I will then plan to arrive 30 to 60 minutes late and they didn't like my sarcasm

No doctoring at all. I brought my mom here who has multiple health issues. We were never able to get an appointment with Dr D but instead saw a PA who said she was consulting with the Dr. They put no thought into my mom's health and didn't even put her much needed prescriptions in. If left up to them she would be dead. The office is gross and they have limited hours. If you value your health find a practice that actually practices medicine. This group is a waste of money and I believe will actually endanger your health by complete lack of care.

Dr. De Monteiro is kind, patient, & knowledgeable in the treatment of the elderly with Dementia/Alzheimers Disease. The Front Desk also a pleasure to work with, & they are always willing to go the extra 110 yards to help you out, especially when your elderly parent has an issue. I would highly recommend Doctor D to anyone who wants a caring Doctor.

I found the doctor to be quite narcissistic and un able to collaborate. I have a comprehensive knowledge of my illnesses and my medications.
He seemed to feel that he should challenge what specialists have recommended and prescribed. I stayed a short time and was very wary until I could find another primary care physician. 87% of primary care physicians prescribe anti depressant medication. He was WRONG about side effects and usages and unable to hear why or another opinion.
This colored every meeting and my inability to develop any trust in his medical ability. Buyer beware.

Dr. DeMonteiro is a wonderful, knowledgeable, caring physician. My only complaint is that others have figured that out, so the time to schedule an appointment with him is longer than I'd prefer. However, he has two excellent Physician Assistants who are much more available (and, I think, are a sort of back door to Dr. DeMonteiro because if you have something they aren't sure of, they can just pop into his office to check with him). I didn't want to give him a good review and have even more people go see him. But, it just made me mad to see him getting a low rating, mostly based

This is the best doctor in the Bay Area by far. I must have 6 different doctors I see and Doctor D is my primary doctor. He is so compassionate and always in a good mood. You are never rushed in your appointment. He will explain things on a level that regular patients understand. The staff is top notch. Always smiling and helpful. A total 5 star experience. I would highly recommend this doctor to everyone.

Dr. De Monteiro is a rare find! He took care of my aging mother for years before she passed away. He was always right with his diagnosis when we weren't sure what was going on with her. My mother had dementia and he was always so kind and attentive to her. He handled delicate conversations with grace. We never had to wait long in his office to be seen. Near the end of her life, I had trouble transferring her from the car to the wheel chair and his staff came down to my car to help me. When we had to have her blood checked to adjust her blood thinner, the staff arranged for a service to

Just wanted to acknowledge Tabitha for her help and amazing service. I made a mistake and let a prescription lapse. Tabitha helped by supplying me with samples until my prescription arrived and also helped set up my mail order prescriptions. She was very accommodating and helped me out of what I thought was going to be a stressful situation. She also took the time to update some missing info in my records. Thank you so much Tabitha, you are a true asset to the office.

They deserve no stars. Office staff is very unfriendly, unhelpful, will not let you talk to a doctor or nurse. They can't even fill out a disability form correctly which cause my Mom to be denied!!! Told my Mom we are finding her a new doctor. One who treats their patients as people not as a number. They don't even say hello when you come in for an appointment. Always felt that we were burdening them. Isn't their job to help people? I'd u hate your job that much find a new profession!!

I had a short appointment in this office and my review is in regard to the front office and staff. I have not been treated by Dr. Monteiro.

I arrived at the exact time I was supposed to be in the office so I was happy to find plenty of guest (patient) parking out front. The two-story building had a clear index on the first floor that told me Dr. Monteiro's office was on the second floor. I took the stairs up and easily found Suite 800.

The front office reception and waiting area has a few seats and a large glass window to the smiling receptionist. She promptly acknowledged me and was very

LOVE Dr. De Monteiro...... Not so much his staff! They NEVER follow up, follow thru or call me back. The doctor is so kind, patient and very understanding and actually takes his time with you. He's knowledgeable and up to date on the latest practices and he is very proactive if he thinks something is amiss with me ie: never hesitates to order lab work or xrays etc. I feel lucky to have him as a physician... I do think he needs an office staff over-haul though.

It is unacceptable how this office treats their old patients. Dr. De Monteiro now moved to High School Ave and it continues even worse! I needed clarification for how much antibiotic I was supposed to take per day, because my condition was rapidly changing, and I called the office 4 (four!) times in three days. Basically, twice the first day and every day after that. I even drove down there in person on top of calling and each time was promised to be called back, which never ever happened. If you do not have an appointment, there is no way to communicate with the doctor. UNACCEPTABLE. Problems
