I needed a new primary doctor because I was fed up dealing with my last doctor and his staff for 17 years. My friend that is a nurse practitioner recommended Dr. Kristen O'Brien and I am so thankful I switched to her. She is professional, knowledgeable and gives me the time I need . I never feel rushed when I'm with her. The Office is clean and the staff is wonderful.

My insurance changed and I had to find a nrw PCP. I chose to see Dr. O 'Brien based on reviews. I cant say enough about her. I am so glad I chose to go here. The reviews I read were great. She was even better than I had expected. She's bright and well versed on many areas. Other Dr's often send you another doctor. She was able to address every one of my questions as well as recommend remedies. She is extremely nice, bright and listens. I'm grateful. The staff was very pleasant as well.

Dr. O'Brien treats both myself and my husband who has had some serious health issues. She has always been on top of addressing his problems, and on one instance would not let us leave until she consulted with his cardiologist who was not taking us as serious as he should have been. She is a great doctor and we are so happy my neighbor recommended her. We feel like we struck gold with her and her staff.

Dr. O'Brien is a great doctor, she was recommended by a friend when I moved back from Florida and now I'm a regular patient. The wait time is never long and I never feel like I'm being rushed out. I highly recommend her.

I've been a patient of Dr. O'Brien's since 2009, she is an excellent doctor, very knowledgeable and always very informative. I recently suffered from a shingles attack and she was very quick in diagnosing it and help treat it. I have recommended her to several friends who are now her regular patients.
