Hassan A. Hassan, MD, is board-certified in medical oncology, internal medicine, and hematology, and practices at Cancer Specialists of North Florida's (CSNF) St. Augustine and Murabella locations. Originally from Illinois, Dr. Hassan obtained his Bachelor of Arts in psychology from the University of Chicago before earning his Doctor of Medicine from Southern Illinois University School of Medicine.

Following in his mother’s footsteps, Dr. Hassan chose oncology with the hopes of bringing comfort and hope to patients facing the unknown. Several years ago, cancer affected his life in a different way when his father-in-law passed away from the disease, despite his otherwise good health and receiving the best care available. Dr. Hassan learned from him that life and death are not in our hands, but living and dying with dignity and integrity are.

As a way to experience a new city and state, Dr. Hassan moved to Florida for what he thought would be a few years. He ended up falling in love with the area and the people, and has been convincing the rest of his family to move here ever since. A former high school basketball star, Dr. Hassan enjoys playing the game with his son and daughter, scuba diving, and “doing whatever my wife and kids tell him to do.”
