Great doctors and staff, although some employees are rude and arrogant. That alone does not represent the entire hospital. Unless it is an emergency, I strongly recommend avoiding busy times. I once waited 4 hours in the emergency room.

Dr. Husseini is an excellent cardiac surgeon. She is professional, very thorough, easy to communicate with, and most importantly, compassionate toward patients and their families. I would recommend her. Thank you for everything you have done, and thank you to your medical team. Well done, Dr. Husseini, and God bless you!

I would leave 0 stars if I could. This hospital failed my mother and put her in danger. Any healthcare professional would have recognized that she was a danger to herself and should have been sectioned. The hospital should have called us if she left. We spoke with several nurses who assured us they would call if she did. She was under their care in room Bigelow 1422A from May 14 to 15, 2023. She was supposed to remain at MGH for several days but was unfortunately discharged on the morning of May 15. There was no call or notification. The next day, May 16, 2023, she was found dead outside Wellington train station; it was also her birthday. Thank you, MGH, for your negligence. I can do nothing about it unless I go to probate court. This organization should be ashamed of itself and how it treats patients. It does not have their best interests at heart and simply rushes them out the door. I will tell everyone I know to avoid this hospital and its affiliates. Horrible, unforgivable, and inhumane.

I just had surgery for kidney cancer and was amazed by the level of service and kindness I received. From the helpful person at the information desk when I first arrived to all the doctors, nurses, and attendants, everyone provided compassionate care, understanding, and assistance before, during, and after my surgery.
Thank you to my surgeon, Dr. Wang, and all the other doctors, nurses, nutrition staff, and attendants.
Thank you.

I visited this hospital's spine department with Dr. Şençak. Unfortunately, I do not recommend him at all. His diagnostic skills were poor, he was uncooperative, and he did not understand the case. He made an incorrect diagnosis. I ask hospital management to replace this physician with a highly skilled doctor because this is considered an international hospital.

Sept 1st 2018, I had a brain aneurysm rupture and was med flighted from Laconia NH. I had collapsed twice walking out of my bathroom so my 12 year old daughter called 911. Thank God she was still awake at 1:30 am or I wouldn't be here. Laconia EMTS treated me terribly and thought I overdosed. The two men kept telling me multiple times that I need to "stand up" as I was crying on my kitchen floor curled up in a ball holding my head. Laconia EMTs kept asking me how much heroin I took and told me we weren't leaving till I told them how much. My son said "My mom doesn't do drugs". The EMTs snickered and said "yeah ok". I knew I was going to die in front of my children so I used every single ounce of strength that I had to get on the gourney. Yes, two men that easily had well over 50 pounds on me if not more, wouldn't place me on the gurney to get moving.
My whole stay at Mass General (all 17 days) was great. I was brought ice cream at 1 am when I couldn't sleep. Since I was bedridden, one nurse "Grace" even washed my hair while I was laying in the bed.
She even tried to get the knots out of my hair. She was incredible and such a sweet, caring girl.
I was moved up from the ICU to the floor above after 15 days, I was told I'd have more freedom without being hooked up to all the machines. I thought that meant I could go get a soda. I was stopped at the elevators and told I couldn't go off the floor. The woman at the desk who stopped me went out of her way and brought a soda to my room. This hospital and its staff are incredible. They saved my life as most people die before reaching the hospital. I'm incredibly grateful to be alive and the hospital staff made my ENTIRE stay more comfortable. I can't thank you all enough for all you have done for me.
Only complaint is one of the social workers. Not the one with the short curly hair..but the other one. She was so rude to my dad.
Dr. Mazwi and Dorothy Booth are the most incredible people out there. Much love to you both! Because of you two...I'm still around for my children who need me.

It is already 2025, and Mass General is still conducting inhumane experiments on animals—drilling into monkeys' brains. If your research is so necessary and justified to save human lives, do it on actual humans. Would you find 100 people every day and drill into their brains? No? Not even to supposedly save humanity? You are only doing this to advance your careers. How do you sleep at night?

This happened in 2020 and still affects me every day. I saw a gynecologist after a life-threatening pregnancy. They refused to let my husband hold my hand until I fought back. They never told me how painful it would be, offered no pain relief, and did not even ask whether about 10 students could attend. It was only a uterine biopsy. It was the most painful experience of my life, and I still break down from the psychological trauma. At my most painful moment, 13 people stared as I fell apart and sobbed. If I had known how deeply this would traumatize me even five years later, I would not have let the pregnancy take my life from me. I hate this nightmare and how much it torments me, and all I can do is write this. If you need a gynecologist, do not go here. Heed this warning and protect yourself, because I could not protect myself 💔

They made me wait 5 months for an appointment, then another 5 months, and when I arrived, they had canceled it without notifying me! I would give zero stars if I could. The staff are extremely unprofessional.

If I could give zero stars, I would. Even with a referral, they repeatedly lose the referral records. It took a year to get an appointment, which was supposed to be today. MyChart showed that I had prepaid over $1,000. They knew the doctor would be away from the clinic for at least a week, yet waited until the Friday before my Monday morning appointment to call and cancel it. I live out of state. The hotel was booked, time off work was arranged, and everything was planned. Another specialist familiar with my condition was also unavailable, but I could see a new doctor in 2026. Now they have to investigate whether the prepayment can be refunded, but no one seems to know how. After not answering the phone today, Patient Relations replied to a message saying it usually takes at least 7 business days, even though I was shown no courtesy throughout this process. Patients should be cautious. I will update or change this review if the situation is resolved more appropriately.

This is a five-star hospital. Our entire family cannot express enough gratitude to the staff, nurses, and doctors for treating our mother with exceptional care and respect. Within minutes of each arrival, nurses and doctors greeted us warmly. Whether or not we were there, they cared for her attentively. We believe their compassionate care and professionalism helped our mother recover so quickly. We will always be grateful to Massachusetts General Hospital. Angels work there.

I went there because of a knee injury. They said I had walked too much and could rest in the ER because I had nowhere else to go until the next day. Security then kept harassing me until the security supervisor assaulted me. He pushed me against the door and then forced me outside. I decided to let it go, found somewhere to sit, and zipped my bag. I then discovered that another bag inside it had been searched. Arthur's hospital will only scam you, steal from you, or hurt you.

If I could, I would give zero stars.
I received care at Massachusetts General Hospital (MGH) throughout my pregnancy and was considered high risk for several reasons. I had early signs of preeclampsia and signs of preterm labor at 36 weeks and 4 days. Although they knew I was high risk, they sent me home when I was already 5 centimeters dilated! I live 50 minutes from the hospital, and the staff knew this. This was also my second child, so labor would typically progress faster. The nurses were extremely rude and arrogant. Because I did not appear to be in much pain and my labor had slowed for 2.5 hours, they forced me to leave. It was absurd. I ultimately had to deliver at a hospital near my home, where I had not wanted to go. I gave birth 13 hours after they discharged me. I was told my baby might not have survived if I had delivered at home or if anything else had gone wrong. I had a placental abruption. Mothers, you know your body better than these doctors do!

My husband, Joe Serrao, has Crohn’s disease and went to the emergency department with a bowel obstruction. He was in severe pain while nurses walked past as though nothing was wrong. I cried and pleaded for help, but they did not respond for two hours. His physician performed surgery and repeated procedures, requiring continual follow-up. After the last procedure, which was supposed to close his stoma, he was not told that he would still have an ostomy bag and pass stool rectally. The emergency department was frightening, with people moved into hallways. I cannot tolerate that place.

I was shocked by this experience. My son was supposed to be transferred to another hospital, but they could not provide any information about the new facility and seemed surprised by my questions. They then canceled the transfer entirely even though I had explicitly asked them not to, delaying my son's treatment. This hospital is dirty, disorganized, and poorly managed. I absolutely do not recommend it.

I was told my bill was under review and on hold after I canceled my payment plan and stopped making payments. Yet only one or two weeks later, a collection agency called me about it! My insurer also denied several claims because the hospital failed to submit the required documents, and the hospital then billed me. My daughter's bill was not identified as hers but as mine. A few days after canceling the payment plan, I suddenly received a bill for my daughter's examination, already in collections. They had previously said the bill would not go to collections because it was on hold. This hospital is extortionate!

Where do I begin?
First, I must honestly say that I consider this one of the best hospitals in the country.
However, my experience tonight was bizarre and disappointing.
Here is what happened.
My daughter was in a car accident.
Boston police called my wife and me, explained the accident, and said she was at Massachusetts General Hospital (MGH).
The officer could not provide many details.
We rushed from Providence to Boston to see her.
On arrival, we were told only one person could accompany her.
In such a critical situation, they allowed only one parent to receive information.
The room was easily large enough for two people.
While my wife had to process everything the doctor said alone, I could only pace anxiously in the waiting room, worried about my daughter.
When the doctor entered to give an update, was one parent really expected to bear that stress alone?
Truly sad and disappointing.

I previously saw Dr. Foreman at the metabolic clinic. From the beginning, I had unpleasant interactions with her administrative staff. Nearly all my blood test results were lost, and I had to track them down myself. The staff were inefficient and rude. I complained to both the doctor and the patient advocacy office. The final straw was a carotid ultrasound ordered by Dr. Foreman; I did not receive the results for nearly six months, and the doctor had not reviewed them. This nearly led to a serious problem. They told me there was an issue with my pituitary gland. I was very disappointed and left the clinic to seek a second opinion at a pituitary specialty clinic. That doctor completely rejected Dr. Foreman's diagnosis. After reviewing my blood test results, he told me that a medication Dr. Foreman had said was ineffective was actually working. Ultimately, I lost trust in both doctors. I now receive care elsewhere. I would not return even for a hangnail!

Just want to take a moment to review our experience at MGH labor and delivery. We were visiting Boston from out of town. My daughter was advised, from her OB/GYN, to go to the nearest ED after describing symptoms that were out of the norm. We were immediately received with kindness and compassion. She was quickly seen and monitored. The women in the labor and delivery unit were lovely. Jen, Mary, and Suzanne went above and beyond to make my daughter feel safe and comfortable throughout her time there. Kudos to these three individuals as well as everyone else we encountered. We are grateful!

I have been coming to this hospital for more than thirty years and highly recommend it. There is no need to go elsewhere for tests because everything is available here. The restaurant offers a wide variety of food, and the cafeteria is open 24 hours, making it convenient to eat while in the emergency room. The service is first-rate, and all the staff are very kind.

This hospital has zero respect for court orders or fathers' rights, and the patient and family advocates are a joke. They completely disregarded my rights as a father, then investigated and handled it ‘administratively,’ i.e., personal apologies from the director and manager of the Saugus branch. Idgaf, I will leave a review for every MGH location.

There are 3 Massachusetts General Hospitals here, and every day they send doctors with lethal-injection syringes to the other two hospitals, which do the same. Their blood feud has continued for at least 20 years and is ongoing. I had to hide under the bed constantly because the attending doctors were so incompetent that, for reasons unknown, they mistook a rival doctor for someone who would kill me. I will never return. This is 3 stars rather than 1 because they still removed a 15-inch circumferential obstruction from my rectal cavity.

Tell me this: now that the vaccine has been shown not only to lack benefit but to be extremely harmful, should we sue the hospital for forcing us to get the shot? Or were we simply supposed to go without surgery? Massachusetts General Hospital told me I could not have surgery unless I got the shot. Healthcare in Massachusetts has completely deteriorated.

I want to express my heartfelt gratitude to everyone at the Massachusetts General Hospital Burn Center, Preoperative Center, and Department of Surgery for the outstanding care they provided during my daughter Haley's recent visit.
Although her scheduled surgery could not proceed as planned because of an unforeseen medical issue that arose that morning, the entire experience was seamless, calm, and compassionate from the moment we checked in at 5:30 a.m.
Haley's preoperative nurse was outstanding: reassuring, attentive, and kind. I was also included in the process and prepared to accompany Haley into the surgical area, which meant a great deal to both of us.
When we reached the surgical unit, we received a truly exceptional level of care. Our surgical nurse was wonderful. Haley's anesthesiologist was excellent, and we trusted that she was receiving the best care. My daughter's surgeon, Dr. Hickey, was outstanding. His bedside manner was calm, confident, and kind. He made us feel as though Haley was his only patient that day, which meant the world to us.
Every other member of the team, including the residents and surgical staff, was equally amazing. Everyone we encountered demonstrated the highest level of expertise and patient care.
Their kindness and professionalism helped turn a highly emotional and uncertain day into one in which I felt embraced, supported, and cared for—not only as a parent, but as a person navigating a complex and stressful situation.
Although we left without the outcome we expected, we were deeply grateful to everyone who stood beside us at every step. The care my daughter received and the compassion shown to me were extraordinary. I thank the MGH team for the warmth, clarity, and calm they demonstrated at such a difficult time.
Honestly, it made me wonder why anyone in this area would go elsewhere. Your team is exceptional. We thank you from the bottom of our hearts.
With sincere gratitude,
Tonya Lucas, Haley's mother

"A great platform for health and wellness enthusiasts!" I recently discovered StrongBodyAI and have to say it is an excellent platform for anyone interested in health and wellness. The website is clean, user-friendly, and easy to navigate, making it simple to find what you need. I especially like how easily sellers can upload and showcase products. As a user, I can find a wide variety of health products, supplements, and fitness equipment in one place. The team behind StrongBodyAI clearly cares about creating a trusted platform focused on health and wellness. Highly recommended for buyers and sellers in the healthcare industry!

Massachusetts General Hospital is the worst medical facility. Getting any information about my treatment or results is a nightmare. I had an MRI nearly a week ago and still have no results. It is shocking that review takes this long and feels like medical negligence. If they cannot provide test results or inform patients about their condition, perhaps they should not provide medical care.

I brought my mother here after she had a stroke in early May. Her case was complex and required collaboration between neurology and cardiology. She was hospitalized for about 9 days, and I stayed with her all day, every day. We also spent about 15 hours in the emergency department before she was admitted to neurology. Everyone was wonderful. The medical staff's expertise, kindness, and teamwork impressed me repeatedly. I am confident she recovered, and she has continued doing well since discharge. People travel from across the country to Massachusetts General Hospital, and now I understand why. This place is outstanding. They saved my mother, and I will always be grateful. Many thanks to everyone on Lunder 7.

Terrible experience. The evaluation was incomplete and the treatment inappropriate. After leaving the Massachusetts General Hospital emergency department, I had to see another doctor for proper treatment. They also tried to fraudulently bill a routine emergency visit as an observation admission. This is not the best hospital in the world. Beware!!!

Christina is a registered nurse in the emergency department. It is astonishing that management allows employees to behave this way. It reflects very poorly on the hospital, especially when your registered nurses cannot be trusted to care for everyone who needs it, regardless of their beliefs.

Twenty years ago, while I was at Hanscom Air Force Base, I was sent to this hospital for emergency heart surgery. I have continued coming here ever since, driving two hours each time. Over the years, I have seen the quality of service decline. At each cardiology follow-up, a nurse records all updates, then the doctor comes in and leaves after two minutes. There is no opportunity to ask questions unless they affect the next month’s treatment. It is ridiculous. However, my last visit was completely different. Someone was staffing the reception area, and only the doctor was present. It was much better. Your billing department is also terrible. They repeatedly use the wrong codes and submit incorrect information to insurance. My last visit was a follow-up and echocardiogram. Your billing department told my insurer that I had been admitted and discharged. After every visit, I have to spend time working with insurance to correct these errors. Someone needs to determine why the billing department keeps making mistakes.
