We are a 3-part community of care dedicated to treating the whole patient – mind, body and spirit – using anthroposophic and integrated treatments. Humanizing Medicine is a direct primary care clinic, which means you pay a low, monthly subscription fee, and you get access to the Dr. whenever you need it, with no co-pays or visit fees. We offer additional healing services such as foot baths, herbal compresses and more – at no additional cost. And our services are available for free to low-income individuals through the Martin Clinic. We also offer integrated cancer treatments, including Mistletoe Cancer Therapy, which can enhance the efficacy of conventional cancer treatment, improving the patient’s outcome and quality of life. Our office feels like a home, and we go out of our way to make sure every patient feels comfortable and respected. We’ll listen for as long as it takes, and refuse to simply  treat the symptoms. Instead, we believe in healing the underlying problem, no matter how simple or complex it may be.

Dr. Hancock vert
Dr. Mark Hancock

Mark Hancock, MD MPH, founded the Martin Clinic in Atlanta together with his wife Enid in 2015. The clinic is strongly rooted in the couple’s belief that everyone, regardless of income level, should have access to quality, integrative healthcare. This philosophy is the driving force behind the donation-based policy that finances the continued development of the clinic to this day.

Dr. Hancock’s  journey through life has been full and varied, and has taken him through art, philosophy, science and even some farmwork before ultimately landing in medicine and at the Martin Clinic. Read about his journey below.

I’ve always loved being in the wilderness and pushing my endurance. The Appalachian Trail became pivotal to me as a teenager, and remains so even to this day. Through my experiences  in the wilderness I learned early on of nature’s amazing potential to nurture the heart and soul.

During my first undergraduate experience I absorbed myself with the thinking process behind science and the assumptions therein. In 1999, I graduated from the University of the South in Sewanee, Tennessee with a B.A. in Philosophy. I wrote my thesis on Immanuel Kant’s dualistic epistemology and how Rudolf Steiner’s Philosophy of Freedom overcame this duality and solved many issues inherent in it.

Upon graduating I left Tennessee and  went to Europe. I worked for the summer on a biodynamic farm and then went to Switzerland where I studied painting at the neueKUNSTschule . I cannot emphasize how important this time painting was for me and my future development as a physician. I feel the absolute focus on receiving sense impressions in an awake, open, and scientific state of mind that occurs when painting a still life, portrait or landscape is also essential in medicine. It also related intrinsically to my earlier philosophical work.

My experiences in Europe formed a significant and solid base for further personal and professional development. As a young boy I’d felt a calling to go into medicine  and these experiences inspired me to pursue that field once again.

I completed a second undergraduate course in 2002 at the University of the South with a B.S. in Biology, making the Dean’s List. Shortly after my wife,daughter and I embarked on a long medical journey together which took us first  to Saint George’s University in Grenada, West Indies. I later completed my Masters in Public Health in 2003 Summa Cum Laude, and threw myself into medical studies. In2008, I graduated Summa Cum Laude with my medical degree, and off we went to England for two years of clinical rotations.

During this time I had the fortunate opportunity to work with Dr Maurice Orange at the Park Atwood Clinic who was treating cancer patients with mistletoe therapy. I found him to be a brilliant and inspiring Anthroposophical physician who became a great source of inspiration to me.We traveled onwards to New Mexico where I completed my family medicine residency as chief resident in 2011.

I am board certified in Family Medicine and have worked extensively in hospital settings caring for patients.  Serious illness that requires hospitalization is usually a life changing event for a person. I am honored to be the agent of that change.

In early 2015 I felt a need to bring the benefits of Anthroposophical medicine to more people. Since then I see patients at our office in Atlanta, as well as during occasional home visits. I am a member of PAAM Physicians’ Association for Anthroposophical Medicine and am working towards certification in Anthroposophical Medicine.

I live in Decatur with my wife Enid, and our six daughters where we have a developing urban homestead with chickens, goats, a food forest and biodynamic-permaculture gardens.

Realizing this was an opportunity to provide cancer patients with truly integrated cancer therapy, she agreed to join his team. Dr. Ketterl will provide information and recommendations for the optimal blend of conventional and alternative cancer treatments, so each patient can make an educated decision on the treatment plan that is best for them. She believes the best outcomes are achieved with an integrated treatment plan, and has seen first-hand how for example mistletoe therapy can improve results and quality of life for cancer patients. She is committed to providing excellent support to each of her patients, spending time to answer all of their questions during the initial consultation, and continuing to support and answer questions over email and during follow up appointments, which can be scheduled by phone or in person.

Lorena can help with many symptoms created by trauma, and can also work well children with developmental disorders.

I have been treating kids and adults locally, out of state, and out of country. The experiences have been enjoyable for both myself and my clients with excellent improvement. The intense treatments have customized timelines for each client but sometimes we can see improvement the same day! In front of the parents and the therapist.It is amazing what we can achieve using the  Padovan Method intensively to positively affect their walking, sensibility of touch, chewing, behavior, verbalizing more sounds, etc. This intense treatment has been used with Autism, Selective Mutism, Neurological  Disease, SABT2, seizures and can be done with any difficulty that the client has presented.
