Dr Kuhan has been excellent throughout the time i have been with Lucio Health. I cannot speak of him highly enough. Dr Kuhan has guided me through the treatment adjusting the dosages when required due to my condition. He is passionate and very knowledgeable, I feel completely safe with any discissions Dr Kuhan makes.

I cannot praise Hari enough for his knowledge and understanding when considering my case. He took great care to understand my particular scenario and to listen to all my concerns. I was fortunate to get the Exacta testing, and from there, Hari was able to give me a protocol I was comfortable with. I've always been able to message Hari with any questions, and his response has always been immediate and detailed, with a rationale behind it. Hari always makes you feel at ease when speaking with him. He's always ready to listen and is never dismissive of any question or concern you may have. I would highly recommend Hari to anyone looking for an integrative oncologist.

Recently I had a blood test result that was concerning. He outlined the possible issues, in an non-alarmist manner, and advised how I should proceed with my GP. After the subsequent tests, Dr Kuhan provided me with a lengthy explanation of the results, and recommendations for intervention. It was all above and beyond the care I received from my GP, and very helpful.

Dr Hari has been life changing, I wish he was my oncologist full time. Not only does he make himself available via email anytime, the level of service is like nothing I have experienced before. His recommendations and opinions are science led. He makes you feel reassured that any advice has been thoroughly checked, researched to make sure he does not put your health at risk. Also the detailed explanation but written in a way a non medical professional can understand makes you feel more in control of your health journey.

My comments in the review above are also relevant to this section. Dr Kuhan is a very easy person to work with and he has been a bedrock in my ongoing treatment and support for nearly 6 years. I have total confidence in both him and the advice he gives.

Dr Hari has been an invaluable source of support throughout my mother's ovarian cancer journey. Having access to a doctor who is available, responsive and genuinely cares about his patients makes an enormous difference during this stressful time. He is extremely knowledgeable and consistently helps us make sense of complex medical information, explains things clearly and provides practical guidance when difficult decisions need to be made. He takes the time to explain the reasoning behind his recommendations, allowing us to make informed decisions. His prompt responses and reassuring manner have helped make a very overwhelming situation far more manageable. I am extremely grateful for his support and would highly recommend him to others facing similar challenges and have already done so on several occasions.
