Charles J. Meakin, MD, MHA

Dr. Charles Meakin
Charles J. Meakin, MD, MHA

My name is Charles Meakin, and I am honored to serve as the Chief Medical Officer of Care Oncology.  I believe this dynamic company is helping shape the fourth field of cancer care of Metabolic Oncology.  My path toward this current role started well before medical school or residency at Stanford University.  My grandfather was a successful businessman and lectured me as an eager 8-10-year-old the importance of diet, exercise, determination, and discipline in a person’s life. He lived vigorously till 94, and I had the honor to be the one of his 26 grandchildren to give his eulogy. My father was an athlete and entrepreneur and when I was 12 gave me the Napoleon Hill book “Think and Grow Rich”. This book ignited the insight of the power of the mind and intention to further couple with my Catholic upbringing and daily prayer.  Although I played many standard sports, my curiosity with eastern thought towards health led me to find the inner-city YMCA Karate program, where I spent the years till college training.  Master Robinson was a 6 foot 4, muscular African American Vietnam veteran who preached vegetarianism, non-violence, respect, and discipline to his large teenage class.  I was one of two white kids, leaned so much and never wanted to miss a class.

After some discernment and consideration of the Glenmary Missionaries, I decided to marry and have a family ultimately and thus went forward and matriculated with the University of Notre Dame and studied economics and premedical curriculum.  I followed college with the University of Cincinnati Medical College back home.  I felt pulled to work with severe medical conditions where the body, mind and spirit interacts to impact the outcome. I liked math and physics and ultimately chose Radiation Oncology rather than the other surgical or medical oncology.  Stanford University was a great training opportunity as they were top in this field. Simultaneously, there were side courses available in San Francisco nearby in hypnosis, nutrition, eastern philosophy, and more.

I started the practice of oncology in 1989, and the 31 years have flown by quickly.   As a physician and clinic director, my goals were always to bring more holistic adjuvants to the standard care and assess their input on outcomes.  These things varied from simple balance training programs, nutrition strategies, supplements additive, portable 02, exercise bands, sleep hacks, and more. All these interventions had four things in common; their purpose was to improve treatment outcomes, they helped other health conditions, they were inexpensive and safe, and they were easy to access.  I became the strange guy in our large oncology group who focused on all these complimentary issues, but they tolerated me as I was always one of the busiest years after year.  Care Oncology continues to provide these four core objectives mentioned above and which is why I joined their genuine mission.

When I am not seeing a virtual consult now or reading a new metabolic strategy with a repurposed drug, I enjoy all things in nature.  My wife Lindsay and I love to hike the North Carolina Mountains trails near our home, stand up paddle boards on nearby lakes and rivers, and come winter heading to Montana to ski and snowboard with our two kids and friends.  Most of my charity work aims to get people outdoors, preserve nature, cancer services, and inspire human potential.  I am a career biohacker with many of the classic tools at home to test theories on myself and offer first-hand information to patients and families.

Dr Samir Agrawal MRCP FRCPath PhD

Barts Health NHS Trust and Barts Cancer Institute, Queen Mary University of London, London, UK

Samir Agrawal is a Senior Lecturer in Haematology at the Queen Mary University of London and a Consultant Haemato-Oncologist at St Bartholomew’s Hospitals and The Barts Health NHS Trust, London UK.

Dr Agrawal qualified at the University of Bristol, UK, trained at The Royal Marsden Cancer Hospital, London, UK, and was awarded his PhD in Tumour Immunology from the University of Paris, France. He is Director of the Stem Cell Laboratory of the Barts Health NHS Trust, and has an interest in diagnostic immunophenotyping. He was a winner of the NHS Innovator Award in 2006 for the introduction of new diagnostic tests for the diagnosis of human leukaemias.

Dr Agrawal’s clinical activities stretch across all areas of haematological cancers, ranging from intensive chemotherapy for acute leukaemia to outpatient non-intensive chemo-immunotherapy for lymphoid diseases, particularly chronic lymphocytic leukaemia (CLL) and other lymphoid malignancies. Dr Agrawal has designed, funded, and implemented studies on myelodysplastic syndromes, invasive aspergillosis and CLL. A former member of the UK CLL Trials Committee, he is a trustee for CLLSA (the patient-led support organisation for patients in the UK with CLL), as well as a NICE reviewer and the haemato-oncology representative on the UK IVIg initiative.

His current activities in the field of invasive fungal disease include a diagnostic study of high-risk haematology patients looking at improved and earlier diagnosis. He is also working to develop clinical guidelines and integrated care pathways for managing infection in the high-risk haemato-oncology setting and to promote best practice and highlight new developments through educational meetings.

Dr Agrawal has published over 70 papers in journals such as the Journal of Clinical Investigation, Journal of Immunology, Blood, the British Medical Journal, and the Journal of Clinical Oncology.
