Dr. Difazio is everything anyone could want in a pediatric neurologist. He is excellent on all counts: communication, making you feel that he is totally focused on you, expertise, patience, kindness. You name it, he personifies what a caring, dedicated, personable doctor should be. The staff is excellent as well--making us feel welcome and always helpful and easy to reach. Keep up the good work. You have been great with my daughter and I will always be grateful for your care.
Silver Spring, MD |
I have to say even though I am giving Dr. Difazio an overall good review because he seems like a great doctor, I am extraordinarily disappointed with my experience at Children's; mainly due to cost. It took two months to get my daughter an appointment, which lasted no more than 20 minutes. With insurance already applied, I now owe them $400 for an office visit. I won't go there again unless absolutely necessary.
Gaithersburg, MD |
Dr. Difazio has provided excellent care for our child. He has provided a wealth of information about our child's condition and has patiently and respectfully answered our questions, concerns, and provided assurances that spoke to our fears over the course of treatment. We know our child is in excellent hands and would recommend Dr. Difazio without hesitation.

in Rockville, MD |
We met Dr. Difazio for a follow up afternoon my toddler's seizure. My husband and I felt that Dr. Difazio reassured us on our daughter's health but was not flippant concerning her episode, which we truly appreciated. All of his staff in the Children's neurology department were kind and attentive, and made our 3 year old felt at ease!
in Silver Spring, MD |
Dr Difazio is a great doctor who came in very kind and patient while assessing my child, who was moving everywhere and touching everything. He also listened very well to my concerns and worked out a plan for my child's needs to adjust his social skills for the better. Thank you for all the help we received and the guidance.

in Frederick, MD |
He's very easy to talk to and is extremely responsive to emails and messages. We always feel at ease as we talk through options for our daughter's care and we leave with a plan of action in place every time. The office temperature could be improved, however. It was stiflingly hot in the waiting/reception area but uncomfortably cold in the exam room.
in Gaithersburg, Md |
Great experience. He explained any concerns well. Put me at ease.
in Montgomery Village, MD |
He is very insightful of the family needs in the treatment of our child. He is comprehensive and humane.

Dr. Difazio was excellent with my 8 yr old. He spoke directly to him, not just about him, and made him feel like he was part of the conversation. He also took the time to make sure we understood the situation/diagnosis and gave some detailed advice for next steps. I would definitely recommend him.
in Rockville, MD |
I take my son, Eugene, who is autistic to see Dr. Difazio every 6 month for medication check-up. I am very satisfied with Dr. Difazio each visit. Dr. Difazio understands patients like Eugene and work with us to manage Eugene's medical issues. Eugene used to have seizures a couple of times each year. Dr. Difazio prescribed Keppra and closely observed his seizure occurrence. Eugene has not have a seizure for two years. Dr. Difazio also asks and listens Eugene's progress very carefully.

in Rockville, MD |
our experience with Dr. Difazio is good . My daughter suffers from mild autism and has partial seizure. Dr. Difazio did not jump immediately to medication unless he was sure that my daughter needs it. We keep our visit with Dr. Difazion to make sure that our decision regarding the type of medication was right. We highly recommend him to any body who seeks his specialty.

Chicago, IL |
We had a wonderful experience with Dr. Difazio. He was very respectful, kind, and made my daughter feel comfortable. He gave me every reason to trust his expertise. In addition, everyone in the office was friendly and competent. The whole process was extremely efficient (which is a relief when you are worried about your kid) -- from calling and getting an appointment for just a few days later -- to the appointment itself. I recommend Dr. Difazio and this Children's clinic highly.
Potomac, MD |
Dr. Difazio is great with my children. He is soft-spoken and honest. He listens to parents' feedback and concerns, and provides information clearly.

He's always been a very caring and supportive doctor for my child. He has helped point us to resources and knowledge with my child's complex condition and given what aid was needed to get needed treatments. Very knowledgeable and personable.
in Gaithersburg, MD |
What makes Dr. DiFazio an excellent pediatric neurologist is his genuine concern about my daughter. He asks questions not only about her health, but her lifestyle to ensure she has a good balance at home, school, and in extracurricular activities. He takes the time to express the importance of conditions, so that my daughter can understand. He also mentions teen topics to make her at ease and put a smile on her face; leaving a lasting impression that she is more than just another patient.
in Rockville, MD |
Extremely friendly, professional and genuine. When talking, you know he giving you an honest and knowledgeable diagnosis, while taking time to clarify for the patient's understanding. His care and patient manner is also exceptional.
in Washington, DC |
Dr. DiFazio came highly recommended by several friends, none of whom know one another and many of whom work in healthcare. He has a wonderful bedside manner, takes the time to explain his observations in layman's terms and follows up immediately on labs, referrals, etc. He also gave us multiple ways to contact him directly so as to avoid the hassle of automated systems, and that accessibility is something I very much appreciate! He's the best!!
Bethesda, MD |
Dr. Difazio is very thorough, yet also very welcoming. He listens intently to his patients and their family members.

1. Got an appointment on the next day after contacting the office for my cousin visiting us for the summer. 2. Took adequate time to listen and examine. 3. Explained the situation and made sure we understood. 4. Answered all our questions and concerns. 5. We left the office with clear understanding of the condition, and the next steps we need to take.

Dr. Marc Difazio is a gentleman and a scholar! He is kind, compassionate exceedingly talented physician. He has an excellent bedside manner and truly cares about his patients He also has a wonderful sense of humor. His nurses are wonderful particularly Alia Fink.
Rockville, MD |
Dr. Difazio was amazing diagnosing my daughter. He gave her an appointment at the end of the day when she was declining and arranged for someone at the hospital to do a spinal tap. When we arrived at the hospital they were expecting us and did the test to diagnose her condition. He communicated with the doctor that did the test to learn of the result late in the day. He is accessible by email, explains very well, answers questions, and treats my daughter respectfully. He is an excellent doctor.
in Gaithersburg, MD |
I would recommend Dr. Difazio to family and friends if for nothing other than his promptness to appointment, thoroughness of discussions and his willingness to write and hand deliver his appointment notes. Regardless of practice area, all doctors could learn a thing or many from how to be on time for appointment which must stem from how he manages his practice, schedule and support staff.
Poolesville, MD |
I've been taking my son to see Dr. Difazio since early 2008. He always takes his time and talks with both my son and me. We have never felt rushed through an appointment. On the extremely rare occasion we have had to wait, Dr. Difazio has always apologized and never made us feel like he had to rush through our appointment so he could get back on schedule. We have complete confidence in Dr. Difazio. His bed side manner with both my son and me is impeccable.
in Frederick, MD |
Great experience with Dr. Difazio. He always takes all of the time needed to listen to anything that is going on with my son. And he takes the time to listen to what my son is telling him. The staff is also wonderful. They have been following my son for many years, and they talk to and encourage my son. One of the best Dr. experiences that I have, and there have been many.
in Olney, MD |
Amazing doctor and guy! Highly recommend him!!
in Rockville, MD |
We sought out Dr. Difazio after a recommendation by our sons Pediatrician; our son had an early diagnosis of ADHD and Tourettes and many of the associated significant issues. We had to wait several months to get a new patient appointment but my wife and I agree that working with him was one of the best decisions we've ever made for our son. Dr. Difazio works from the point of view of medical expert, parent and patient himself-cannot recommend him highly enough. His staff is also outstanding.
in Bethesda, MD |
Dr. DiFazio cares - he knows my kid and me. He asks how we are both doing. He takes an interest in our family well being. He shares personal experiences. He is thoughtful.
in Silver Spring, MD |
I very much liked that Dr. Difazio began the visit by talking to my son directly for information before he asking me, as the parent.He was very thorough in his explanation to my son and made sure that we both had a chance to ask questions. I also appreciated that he made recommendations based on an integrated perspective looking at both physical and behavioral health factors, which made me feel that he really listened and took into account everything that we told him in a short amount of time.
