    We've all met really good doctors. They're good, they know it, and they act like it. Dr. Merguerian is on a different level. He's SO good, that he doesn't need to show it. You can tell how brilliant he is very quickly just from the way that he talks and carries himself. For such a good doctor to show the compassion he has shown for both our son and our family throughout the process has made a lasting impression. He has taken the time to thoroughly explain the procedures and answer all of the questions that we have. We feel incredibly fortunate and thankful that we happen to live in the city where he works.

  • Erin Manchester, NH 08.20.13

    Dr. Merguerian is a highly skilled, compassionate doctor who was able to take our child from a "scary place" following several urethral reconstructions with complications and poor outcomes, which were performed at a top rated hospital by a different surgeon, and "fix" the problems. Dr. Merguerian allowed us (parents) to ask questions without getting defensive or frustrated and gently reassured us throughout the years he cared for our child. We were deeply saddened to learn that Dr. Merguerian was moving out of our area and would not be able to follow our child further, however we continue to be thankful for the highly skilled and caring service he provided while he was in the Northeast region.

  • Harvest Newbury, Vermont 11.20.11

    Dr. Merguerian is a fantastic Doctor who has saved our daughter's life from when she was born August 29, 2005 to current. He has performed many surgeries and reconstructions on our daughter from her cloaca anomaly, repairing of her fistula to bladder surgery and many more. He worked hard to get Rylie to a state were she could function and be as independent as possible. He is very caring and takes pride in his work. We highly recommend Dr. Merguerian. Your child will be in good hands. If Rylie needed another major surgery we would travel across county just to have him perform the surgery on our daughter.

  • Megan Winchester, NH 10.19.11

    Dr. Merguerian is an amazing surgeon with a very steady hand. He has performed 3 surgeries on my son while he in practice in Lebanon, NH at DHMC. These surgeries were for my son's epispadias fix, initial closure for BLADDER EXSTROPHY, and hernia repairs. Your child will be in good hands with Dr. Merguerian. :)
