I've always been very particular about my doctors, I prefer a family type of atmosphere that barely exists anymore. However, Diablo family physicians in San Ramon is the next best thing. I was recommended to go there by a friend when I was looking for a new Doctor and they didn't disappoint.. Very friendly and professional at the same time. Would recommend them to anyone

Dr. Mark and his staff are excellent. They all show a true level of caring that is not found today. That is not to say that other Doctors and their staff are not polite, and professional. With Dr. Marc you get the added sincerity, and caring that others seem to be missing. He makes you comfortable, and I trust him unequivocally. He listens, and most of all, hears what you are saying. The Best!!

Diablo Family Physicians is a great office. The facility is bright and clean with easy parking. The staff is friendly and efficient. My provider is Sachie, and she is extremely thorough and helpful. She is the best primary care provider I have seen.

Diablo Family Physicians is wonderful! They have great service and are very easy to work with. Sachie Nguyen-Trung, FNP was amazing, she is very thorough and truly cares. I didn’t feel rushed and I felt heard as a patient. Her goals for me were also very realistic and understanding of my busy schedule as a mom with two little kids. I actually looked forward to making a follow up appointment.

I learned of the Lean MD program recently and scheduled an appointment. I first met with the NP Sachie and she was great at explaining the program. Totally honest about how overwhelming it can be in the beginning, which it was but the staff is always there to answer any questions. They also give you very detailed information to take home and review. She was also really informative about nutrition, dietary needs, reviewing past medical history and we came up with an ideal goal weight for me. I am not one that has ever succeeded with diets or losing weight. I have been in the program for just under

I definitely would recommend this office to anyone that wants to feel cared for. My husband and I have been going to this office for years. No matter what is happening in our lives we feel listened to and that our needs will be met. We also are seen in a timely manner. We moved to Fairfield a little less than a year ago and we continue to go to this office because we are so happy with the care.

Diablo Family Physician is a very patient friendly practice. The office staff are always able to get you in to see a Doctor on a moments notice. Dr. Mark & Tim Sayles are personable and spend as much time needed to explain your health problems.

We love our NP and have seen a few of the doctors in the practice. Always have been thorough with my children and me. Office staff is always trying to help us out as much as they can too. I drive a little out of my way just to go to this office. Finally, a practice I really like!
