Patient Reviews Request Appointment
Mark E. Johns, MD, is a medical oncologist and hematologist who has a special interest in breast cancer, colon cancer, lung cancer and multiple myeloma. He is a member of the American Society of Clinical Oncology and serves as a principal investigator for gastrointestinal and genitourinary clinical trials at OHC, always encouraging his patients to enroll in clinical trials to gain early access to the latest treatments available.
“Cancer never rests, and neither does our team of researchers who are devoting their lives to finding new ways to battle this disease. There are so many exciting new findings being discovered every day in cancer clinical trials and I want my patients to have the opportunity to use these promising new treatments to fight their cancer,” said Dr. Johns.
It’s also important to Dr. Johns that his patients receive the same attention and treatment he would give his family. “I chose to specialize in oncology because of the fulfillment that comes from treating patients who are dealing with such a critical illness. I stay abreast of new and emerging treatments so I can give each patient up-to-date options in treating their cancer.”
In his free time, Dr. Johns likes to spend time with his family and golf.

I totally trust Dr. Johns. I value his opinions and am very glad he is my doctor. He has taken care of me ever since Dr. Ruelman left. He is very knowledgeable and helps me understand everything. And, he never forgets to ask me if I have any questions. – Anonymous, May 2022
I highly recommend Dr. Johns. He takes the time to listen to you and your concerns, not making you feel rushed or crazy for asking a question. Very nice and kind. Actually, the whole staff at OHC is AWESOME!!! – T., April 2022
