I've been going to see Dr. DiFazio for years and he is always been concerned for my well-being well beyond the specific condition that he's treating me for. He's very knowledgeable and takes the time to listen and understand what's going on with me.

After my child endured a concussion, the ER doctors referred us to Dr. DiFazio for a follow-up appointment the next day. My child had fallen, hit their head, blacked out, threw up three times, had an extreme headache, was disoriented for two days, and was extremely fatigued for several days. Point being, their concussion was significant. Dr. DiFazio recommended the opposite of the ER docs. In fact, the medical community consensus is that children should abstain from physical activity - and some

Bad experience. Save your child life and don’t go to this doctor. Why is he a doctor he has no ideea about neurology. He is not getting back to your emails, no emergency phone number to call. His appointments are less than 2 min. You wait months to schedule an appointment with him and he is trying waking you to the exit after 2 min in his office. No follow up with any blood work or concerns. He is not just invisible there he is very incompetent, not the required training to be a neurologist.

I strongly recommend Dr. DiFazio to family, friends, any everyone in need of a neurologist. He has been my primary neurologist for the past 5 years and has always provided the best and most helpful care. Dr. DiFazio, staff, and the other physicians are all very friendly and welcoming. Scheduling appointments and/or requesting prescription refills could not be easier, you have the option of scheduling/requesting via online patient portal or phone.

We just got back from our first visit with Dr. Difazio and had a very positive experience. Dr. Difazio is the medical director of the outpatient facility in Rockville, MD. He was very thorough in his examination, calm in his demeanor and very receptive to all our questions and concerns. He explained everything both to us and to our child. We appreciated how he was very perceptive to our heightened state of anxiety and spent a while addressing our concerns. Overall very good doctor.

It's impossible to get a hold of Dr. Difazio or to be called back by him. The nurses that I've dealt with have not been very sympathetic, understanding, or too helpful when it comes to questions I've had about my son's care. It's been very frustrating!

My daughter had suffered a head injury four days prior to our visit. Dr Difazio spent ample time examining her and giving us feedback. He answered all of our question and provided us with the background research to put our mind at ease. He was very thorough and created an atmosphere in which my daughter could comfortably ask questions and be involved in her own health care.

Dr. Difazio came in the room right away, no waiting, and explained in detail about my daughters conditions, ensured completely we did not have any further questions and took the time to explain how we would communicate through the online portal all in record time without feeling in any way rushed. Great bedside manner, lovely.

Dr. Difazio was fantastic. He was thoughtful, professional and friendly. He made our son feel comfortable and did the same for my wife and myself. I would recommend him to anyone who has to deal with neurological challenges & concerns for their child, especially as most are unexpected and worrisome. His staff was courteous and the facility was well designed (with keeping little people occupied) well thought out and executed.

I first meet Dr.Difazio, MD on 9/18/17. Very pleasant and child friendly. He greeted us and instantly made a connection with my daughter. Took his time while we were in the examination room doing his assessment and evaluation. The front desk staff was very friendly. The only negative is that there is some type of repairs being done at the entrance of their lobby/waiting area which made it noisy and clustered. Also the availability of appointments are too long of a wait.

Dr. DiFazio runs a tight ship. Most importantly he is a highly regarded Pediatric Neurologist and for good reason. It puts my mind at ease to know he's on our team! We were seen in a timely fashion with very little waiting. He goes above and beyond to provide patients with valuable, pertinent information about resources available to people with special needs. There are multiple ways to reach him or his office which makes communicating with them easier.

He was more positive, than others doctors that I have seen about my health. He was good at explaining things to me, and asked me ignore I understood him. Even if he wasn't able to give a definitive answer, he was still able to help by prescribing medications that would help me.

Had a wonderful appointment today with Dr. DeFazio. He was prompt, courteous, and took his time talking to us and answering all our questions. I also have to commend his support staff. The administrative team and Nicki (the nurse) are awesome. Nicki was extremely helpful to me this summer when we needed to get short term Rx filled for my son who went away to two different summer programs.

Dr. Difazio was wonderful. He spent time listening to not only me but also my sons, one of whom is on the spectrum and has extreme anxiety talking to people. Dr. Difazio was great at relating to them and his answers were direct but not condescending. If I could give more stars I would!
