Dr Lyon, Is really kind and thoroughly investigates the issues. My issue was complex and he kept digging until he got to the root cause of all of them. I would highly recommend him.
I found Dr Lyon's approach to the appointment to be professional, sensitive and down to earth. He took the time to explain my diagnosis and treatment options in detail so I could make an informed decision as to the way forward.
I thought Dr Lyon was really excellent. Very pleased to have been referred to him. I find hospital settings and appointments incredibly stressful due to having been an immunotherapy cancer patient for many years at the Marsden. Dr Lyon however quickly put me at ease and I liked his calm, thoughtful, gently humorous and kind manner - he quickly created a sense of trust for me. On the medical front his clear communication and considered guidance was much valued by me. I feel like I'm in very good hands with him. Thank you.
Dr Lyon has been very thorough in investigating the reason behind my recent symptoms which resulted in an MRI showing that I had had a small heart attack. He provided very clear explanations regarding my condition. He was also very fast to react when I had a problem with a reaction to the medication prescribed and has communicated quickly a plan for further investigations. This altogether has given me reassurance that my problem is being dealt with efficiently and professionally.
Thank you. So helpful. And gave us the time and results very quickly. Feel safe with him.
Dr Lyon gave Philip great encouragement that he could make him feel better. He listened to the symptoms and quickly got further tests and scans sorted which were all done the same day. He kindly telephoned that same evening with the results and a further plan of treatment.
This was a 6 monthly follow-up with Dr Lyon. He talked me through the results of tests I had had a few days before. As a result he altered the drugs I take and asked me to have blood tests in 2 weeks time. Dr Lyon is a superb professional and I have every faith in him.
This was my first time of meeting him. He instantly put me at ease. He was very amiable, seemed genuinely interested in my journey. I liked him
