We have only seen this doctor one other time while going to this practice, but he is definitely very good with kids (I know, he is a ped!). He has a very special way of getting the right information to treat his patients.

Every year, my daughter comes to Dr. Grella, and she's always looking forward to come to see her doctor. He is an amazing doctor. The staff are outstanding, very supportive. Because of Dr. Grella, my [redacted]-year-old has been saying that she wants to be a pediatrician. Till this day, she wants to be a doctor because of him. We're very lucky to have a doctor like Dr. Grella. Thank you.

Marc Grella has been my family's pediatrician since my oldest 12 years ago to my youngest who is six. He is amazing in responding messages and explaining everything in detail. And anything that I've ever needed for my children, he is the best. I recommend Dr. Grella and the MGH department to anyone and everyone who will listen.
