he throws drugs at you and makes you come back for any possible thing he can just to bill you again, regardless of how long it’ll take for you to get the treatment you need. even if you need a referral to a specialist for something you’ve already discussed with him that he couldnt solve, he will make you come back to get it so he can bill. can’t help but feel he’s just in it for the money.

I have been with Dr. O'Brien for over twenty years. He has been a great doctor and when I need a specialist he sends me to some of the best.

Great doctor, been seeing him for 15 plus years, love the personal care I get from his office staff and medical staff. Hope he’s practicing for years to come!

I have never been to a more rude doctor ever. Not only was OBrien dismissive and curt to me, but he even argued Family History (brother’s proven diagnosis through biopsy) - just because my brother outlived the prognosis of death in his teens and he is almost 50. He has never met my brother, nor, evidently, the hand of God or quality medical care! I’m not sure what ailed him the day I went for my visit, but goodness, I sure hope he has better days now!! I won’t be back to find out...

I have been visiting Dr O’Brien most of my adult life. He is both friendly and professional, and frankly I wouldn’t trust anyone else with my health.
