I telephoned Dr Jack Singer quite instinctively after finding his name & details at the top of a Google search when our 5 year old son had been poorly with a fever, severe lethargy & vomiting for 12 days. For the most recent 5 of these days he had been an inpatient at our local hospital, on IV fluids & antibiotics being treated for query sepsis & question marks over Coronavirus & Meningitis. During this time he developed slurred speech & lack of concentration. However, at this point , there was no clear diagnosis or treatment plan & frighteningly for us, our little boys’ condition was clearly deteriorating. Dr Singer telephoned me within 2 hours of speaking to his secretary. I spent about 15-20 minutes explaining our son’s presentation & recent history & he immediately diagnosed Encephalitis (of 3 possible origins) & advised on medication to be started immediately & a forward plan to include urgent MRI & Lumbar puncture. Dr Singer telephoned me back within an hour of our first conversation with more advice & made it quite clear we could contact him 24/7 if we had any concerns. In the absence of a clear plan from our hospital, the Paediatric team were very receptive to Doctor Singers input, spoke with him on the telephone & acted on his advice immediately. Within 12 hours of starting the medication our little boy began to demonstrate clear improvements which continued as the days went on. Following more results, our local paediatricians started him on further medications & we were able to discuss the ongoing treatment with Dr Singer regularly. His input, advice & transparency meant that we were able to gain reassurance from him every step of this traumatic journey & it enabled us not only to understand but to plan for the Doctor’s ward rounds at our hospital so that all of our questions & concerns were answered. 2 days after our telephone consultation the team of Paediatricians at the hospital our son was being treated confirmed the diagnosis of Encephalitis! The most Amazing thing about this situation is that Dr Singer did not once see our son, not even by video link yet was still able to make an accurate diagnosis. In our opinion Dr Singer is clearly extremely experienced, demonstrating a mixture of friendly professionalism, with an incredibly confident & straight talking, yet humble manner. We found ourselves in an entirely unexpected & terrifying situation & Dr Singer has given us the most precious gift any parent could ask for. As I wrote earlier, our telephone call to him was instinctive & we did not read any reviews before making the call. Of course, everybody’s personal opinions vary greatly but the sincerity behind this review is unquestionable! Based on our experiences with this incredible gentleman, we will travel (5 hours) to his Jclinic as soon as we are able, to have our son followed up for immunological testing! ‘Thank you’ is simply not enough!
We are totally happy with the treatment my 5year old son gets here. I highly recommend Dr.Singer.
Highly recommend Dr. Singer for my child. Very efficient and helpful in diagnosing all medical issues. Has a lot of patience with us and is kind and courteous with our child. Has the time to answer all questions and goes into in depth detail about all situations. My child actually runs into his office room each time we arrive he’s that excited!
We feel a lot more relieved after visiting, we were taken through everything slowly and understood. Detailed explanation, excellent examination. Would definitely recommend.

Excellent doctor. His diagnosis was very accurate. We went there with our baby, as he was high fever, which was not dropping down, and as soon as doctor prescribed him his medicines, in just one day my baby started to feel better.

Excellent advise we were very sceptical in the beginning but all his advice worked and our baby got much better in the matter of a couple of weeks
Thorough blood tests were done on my son. These returned the results of low iron levels. Will be back to see a specialist doctor to help us with his adenoids.

We have been under Dr Singer since 2017 who instantly diagnosed that our then 4 year old had asthma and some allergies. She has been a different child since having the correct diagnosis and treatment. Thank you Dr Singer
Highly professional, always precise in the diagnoses and very reassuring when he treats your child. Highly recommend him to new parents!
We have complete confidence on Dr Singer.
Always very friendly and a great doctor. Would have no hesitation in recommending him.
Went to see Dr Singer as my daughter as we couldn’t get rid of her worms and he sorted it out straight away. A life saver!!! My daughter loved coming to see him and now refers to him as the toy doctor.
I have visited with my son for an ear infection and he was happy to be visited by the doctor. The pain and the ear infection went away pretty soon and he could play again shortly. I would recommend to visit Dr Singer
Fantastic experience, very professional and vaccines he gave to our baby were very high quality with no side effect at all, including no fever after the vaccination.
Doctor Singer worked miracle with my baby: the baby was born week 38 and she is the small twin, after my c-section I couldn’t breastfeed, and my baby was losing weight, she lost 5.5% by day 3, and lost up to 10% by day 5. NHS told us to feed her ever 3h, and we were worried as she had no energy to feed and we had to wake her up to feed. We saw Dr Singer in day 7, he changed her formula and feeding plan, and in 1 week my baby went back to her birth weight, then kept gaining weight and taking more ml of milk. She now can move, has energy to cry, bottle feed, and even breastfeed. We are over the moon with the fast results.
Thank you Dr for the analytical eye and attention to detail. Makes it look easy.
Lovely doctor. Helped us massively with our son who was a very difficult baby and Dr Singer helped us realise he has reflux and milk intolerance which our local GP didn’t help with at all. Appts always on time and Dr Singer is always contactable by email and telephone. Thank you very much!!
The best and kindest paediatrician. Thank you so much.
Dr Jack Singer was great at putting our mind at rest, suggesting further areas of investigation and quickly referring us to relevant specialists, after months worrying about a recurring pain in our son’s foot - something which no other doctor had been able to do until now.
Dr Jack Singer was amazing to diagnose what our little one had... very professional, and gave all the attention we needed. We definitely recommend Dr. Jack.
Approachable, thorough and extremely knowledgeable. Thank you for taking care of our daughter
Dr. Singer was able to get our daughter in on the same day while we were in town from the US. He was able to get her a prescription that got her ear infection better so we could fly home at the end of the week. Would highly recommend.
Dr Singer was great, we saw him straight away for my daughters skin condition and he recommended us a cream and it worked wonders! Her skin had a dramatic change within the last 3 days we saw him, thank you so much for your help with my daughters skin! I’m so grateful!

Brilliant result. Went from being top to toe with eczema to having clear wonderful skin after one visit and 2 weeks of following Dr Singers directions. We’re delighted
Always reassuring and very efficient! Thank you.
