"Mike Markiewicz is an outstanding paediatrician and he has looked after my children (two of them from birth) ever since we moved to London six years ago. I trust his judgement completely and he has proven time and time again how accurate he is in his diagnoses. In addition when my children have been seriously ill or in hospital, his medical expertise, talent, his meticulous thoroughness and care, have been invaluable. He is always available and responsive and it is very comforting to know that my children are in such proficient hands. I would not hesitate to recommend him to anyone and have already sent a handful of my friends to him, and will continue to do so."

"Dr Markiewicz is an outstanding doctor, but also an extremely kind and compassionate human being.  He is extraordinarily generous with his time and care: picking up the phone and answering numerous texts day and night no matter how serious the problem.  He goes over and above the call of duty on a daily basis, and we feel very lucky and grateful that our children are able to see him.  
When one of our children was born with several unexpected problems, Dr Markiewicz immediately came across to a hospital he doesn’t practice at and gave us both advice and a great deal of support at a time we were in crisis.  Furthermore, he arranged for the leading Paediatric Cardiologist (who also doesn’t normally work at the hospital) to visit us the following day and conduct a complete and thorough examination.  As one of our children has disabilities, Dr Markiewicz has supported us wholeheartedly through both good and bad times, recording our child’s progress in a thorough manner so that experts have taken us very seriously when investigating any deterioration.  He a quality that can be rare in doctors – an open mind – and is happy to investigate new areas of research that might help a sick child and point us in the right direction: through Dr Markiewicz we have gained access to a host of specialists in paediatric care that we have needed on many occasions.  
Dr Markiewicz is undoubtedly an amazing diagnostician.  For example, on one occasion I texted him a picture of my toddler’s eye as we were in the English countryside. The local GP had told us to go to A&E, but when we arrived at the local hospital the A&E team told us to come back in a few days if things got a lot worse.  Dr Markiewicz spoke to the A&E doctor (who wasn’t a paediatrician) at length and explained that our daughter needed to be on an IV drip immediately, otherwise her eyesight was seriously at risk (and, as we later found out, that she was at risk of infectious meningitis from the illness).  Eventually, he asked to speak to us and told us to leave the hospital and drive back to London, where he would have a room and medication waiting for us (this was on New Year’s Eve).  We arrived a few hours later to find doctors and nurses waiting for us: they were shocked that she had not been treated immediately. Subsequently, Dr Markiewicz came to see her daily and monitored her progress.  
I would add that this dedication and support extends to all our children: he has helped us navigate the typical and atypical childhood hurdles with a great deal of care and attention."

"Dr Markiewicz has been my children’s paediatrician for 6 years. His passion for helping children, dealing with health related challenges and wider experience is, in my view, incomparable.
He was instrumental in helping get my youngest son diagnosed with autism spectrum disorder (ASD), for which I am forever indebted. Thanks to the early diagnosis, my son has the best chance of reaching his full potential, as I was able to accept and deal with the challenges associated with ASD. I sincerely admire Dr Markieiwcz both as a person and paediatrician."

"We have been seeing Dr Markiewicz regularly for the past few years. Dr Markiewicz is brilliant with our three children. He responsiveness is second to none. He is always available, be it day or night, and he has been there for us during both the good and the difficult times - we had premature twins and Dr Markiewicz was there for us every step of the way. 
When our son was hospitalised with what appeared to be a chest infection, Dr Markiewicz was instrumental in accurately diagnosing his condition. In fact, he was the only doctor who got to the bottom of the problem.
Having Dr Markiewicz as our paediatrician has been a huge source of comfort to our family. We feel we can rely on him 100% for anything to do with our children’s health and well-being."

"I am so grateful to Dr Markiewicz for taking such good care of my two boys. He is unbelievably responsive and thorough in everything he does, leaving no stone unturned. Truly an amazing paediatrician who I know I can trust in any situation. He gives me total peace of mind!"

Mr. and Mrs. Herrmann

"We have gone to Dr. Markiewicz for the last 7 years (since our eldest was born). We have 4 children and have relied on his expert care throughout.  Dr. Markiewicz's excellence with regards to interaction with both the children and their parents is best in class.  His knowledge and ability to clearly articulate the care needed when one of our children has been ill, has been a truly fantastic.  I cannot say enough good things about Dr. Markiewicz and his care as a physician.”

Emma Pliner

"Dr Markiewicz has looked after my two teenage boys since birth. His calm, unflappable manner together with his amazing house visits have been a constant source of reassurance when parenthood gets tough. He is always keen for the boys to be ‘fixed’ as soon as possible and back to playing sport or at school no matter what the complaint of the day or drama he is presented with. I recommend him to any parent who wants resilient kids whilst still being conscious of any health concerns."

Sayoko Teitelbaum

"Dr Mike Markiewicz is, in my view, London's pre-eminent paediatrician. He is incredibly knowledgeable, thoughtful, resourceful and responsive when it comes to my children's health needs."

Natalie Ljungberg

"Dr Markiewicz has been amazing to me as a young (and neurotic) mum of two. He is extremely supportive and always answers the phone no matter whatever time of day, however small the problem may seem. He does home visits for me that have been invaluable, as I don't often have the time to get out. He never sugar coats issues: when it comes to your kids you need someone to tell it how it is. I feel very grateful to have a doctor as responsive and hands on as him; I would definitely recommend him to anyone."

Miriam Cooper

"Over the years Dr Markiewicz has acted as paediatrician to both my youngest sister and now to my daughter. I always turn to Dr Markiewicz for advice and guidance on any health-related matter regarding my daughter as he has been, and continues to be, an invaluable source of support as I watch her develop and grow."
