I've seen a few psychologists prior to working with Doc. O'Brien. He is by far the best. Always helpful and professional .

Dr. O'Brien was recommended to me by a friend. Truly, without a doubt he has saved my life. The man is a wealth of understanding and knowledge. A leader in his field and I'm very thankful I have access to him. I only wish everyone experiencing the same difficulties could have access to someone so professional and understanding.

Dr. Sean has been an unbelievable help in dealing with occupational stress. I cannot emphasize how he has helped me and others in my line of work.

I experienced a life threatening trauma that took several days before resolution. I then went to Dr. O'Brien, knowing I was in a high risk group for PTSD or other problems. He was referred to me through some police who had experience in handling these difficulties. Immediately he won my confidence and trust. He laid out a detailed plan on learning about the structure of what happens in trauma and how we can manage or treat its aftereffects. He was very insightful and tailored his explanations to my way of learning. Through my therapy with him, he has been available for appointments off schedule when little 'bumps' arise. As well, he has helped me in the numerous documents needed for insurance claims. I would recommend him for anyone interested in learning about trauma and recovery, prior to or after a trauma. For me, the results I've gained by working with him on my recovery have enabled me to get much normality of life back. It's not over for me yet, but I do see great results.

He is a doctor who understands military culture - not many do. He helped me turn my life around. My family and I are glad we found someone who could help us move forward.
