O Fallon, MO |
Dr. O'Brien has been my doctor for 20+ years, as well as my husband's. He takes time to listen and explain medical issues thoroughly. He never rushes you and I feel confident in the answers he gives me. I trust his knowledge and opinions completely. His long time nurse Becky is awesome also!

Never got to meet the man; never even got an appointment; I was curtly told that it would be a month before they had any openings and then the conversation was abruptly ended and they hung up.

Since I have not been taking new patients for the past 1-2 yrs, it is impossible that this individual could have received the response that "it would be a month before they had any openings" in October 2016.

I have been seeing Dr. O'Brien since I was born. I love that the staff are friendly and make you feel as at home as one can feel at the doctors office. It is that familiarity that eases nerves and makes going to the doctor easy to do and not a complicated process.
