Kristen Anne O'Brien, MD 3001 Express Drive North, Islandia, NY 11749

"Went to Dr O’Brien on recommendation from my wife Judy. After 15 minutes she looked at her watch and said “Your time is up”. I stated that I had more issues to discuss with her. She said I have to make another appointment and walked out. Any doctor that I told that story to told me that she was guilty of malpractice for leaving me an I should file a formal complaint with the AMA. I just moved on."

"Dr. O'Brien is great and gets 5 stars. My husband had a stroke and was released end of May. Called Dr. O'Briens office and he was suppose to see her within 10 days. Dr. O'Brien called me on 6/10 to find out what happened and she would go over everything when I see her. I spoke with Gail who couldn't get me in with an appointment and put me on a waiting list. Today is 6/28 still no call from Gail or any apt. He has a routine scheduled apt 7/12 with no help from Gail. Sadly if I didn't like Dr. O'Brien I would be gone Excuses for not calling me back was the number was wrong. Pathetic for a team leader who gets 1 star"

"I have been a patient there for many years. Now I am leaving the practice. Was a good in the past, but horrible service now. The front office staff are rude and incompetent. Hate northwell health. When you call its a service and you can't get anyone in the office. Showed up when I made an appointment and the office said that I didn't have an appointment. I refused to leave until I saw someone. I made a well visit a year in advance for April. They called me last week and said Dr. O'Brien needs to cancel. She won't be in the office. Decided to leave the practice. Then I filled out the forms to get my records sent to me. I actually went in the talk to the receptionist and fill out the forms. They never sent it out to the company. Horrible place. So upset because dr. O'Brien was a good doctor, but northwell took over and it has been a nightmare. The receptionists have no idea what they are doing. Find another doctor. Now I am going to catholic health service. Sad that the entire health care system is broken."

"Professional, compassionate care. I never feel rushed, no matter how crowded the waiting room is. The office also has daily walk-in availability for times when you don't have an appointment. Entire staff has same high standards set by Dr. O'Brien. Highly recommend!!"

"Excellent office. Professional, caring and on time. Dr. O'Brien and her staff are a pleasure to deal with. They make you feel very welcome and at ease. Dr. O'Brien offers subtle lifestyle changes that can improve your overall health and well being. Recommended highly."
