Tom was great with my daughter at explaining exactly what he was doing in a calm and entertaining way.
Tom is an excellent consultant. Warm, extremely knowledgeable and great at explaining medical terms in easy to understand ways. He made our daughter feel comfortable and was always on hand to provide advice. Under his supervision, our daughter’s peanut allergy was diagnosed and treated using peanut immunotherapy. I highly recommend Tom to anyone looking for top Paediatric Allergy diagnosis and treatment.
We went to Dr Marrs for an initial visit to check on our toddler's suspected milk allergy. Dr Marrs was very helpful, thoughtful, reassuring and addressed all our questions while simultaneously keeping our daughter engaged.
Lovely doctor really concerned about patient well being
This appointment was very helpful and Dr. Tom explained everything beforehand very well
He is sooo good 😊 he does the most less painful pinch if it hurts it’ll soon not hurt. He’s smart and talented but he’s also very funny 😁 If you’re here for eczema he’ll just talk make jokes give you the cream and then look 👀 at you’re eczema.
Recently had an appointment for my daughter with Dr Marrs. He built trust and great rapport with both myself and the patient from the onset. I felt heard as a parent, and received sufficient advice of further management. I appreciated his holistic approach - he reviewed more than my initial concerns about a possible allergy, and we agreed on further follow up plans. Genuinely the best experience we’ve had with a paediatrician so far. Would definitely book him again if needed in the future. Also appreciated being seen on time :)
Dr. Tom was very patient, empathetic and above all super helpful. We appreciate his help.
