Dr. O'Brien's Experience

Patient Feedback

I saw Dr. O'Brien for Primary hyperparathyroidism and he performed surgery on my neck to remove the tumor in my parathyroid gland. He is terrific. Dr. O'Brien is kind, explains things really well and gave me great confidence going into a surgery where he was going to cut into my neck. I recommend him wholeheartedly...he is a terrific surgeon and just a really nice person.
