John Hanlon, M.D.

President of Little Company of Mary Hospital

John Hanlon, MD, is a comprehensive ophthalmologist who, prior to merging with Arbor Centers for EyeCare in 2016, operated a solo practice in ophthalmology for 29 years in Evergreen Park and Oak Lawn. Dr. Hanlon believes in the importance of listening to his patients, and takes an active interest in his patients’ other medical problems because of the effect those problems can have on vision.

Dr. Hanlon grew up in the Beverly neighborhood of Chicago and attended the University of Illinois College Of Medicine. He completed his ophthalmology residency at Loyola University in Maywood, and immediately opened his ophthalmology practice in Oak Lawn, moving to Evergreen Park in 1993.

Dr. Hanlon believes that patient education is a key to good patient care, and enlists his patients as active participants in their care. He is also active in the education of other medical providers, teaching medical students from the Rosalind Franklin School of Medicine at The Chicago Medical School, as well as lecturing to physicians and nurses at Little Company of Mary Hospital.

He completed a Master’s degree in medical management at Carnegie Mellon University in 2015, and has served in several leadership roles at his hospital and in his professional society. In 2018 he became President of Little Company of Mary Hospital in Evergreen Park, where he is charged with helping to improve the quality of patient care and ensure patient safety, subjects about which he is passionate. He believes that the future of high quality medical care depends on the active leadership of compassionate physicians.

Dr. Hanlon enjoys spending time with his 5 children and (especially) his 2 grandchildren. He and his wife enjoy traveling, exercising and reading.
