Charles W. Hollen, DPH, MD 11100 Hefner Pointe Drive, Oklahoma City, OK 73120

"I believe this man saved my life. I was diagnosed with Stage 3C triple positive breast cancer. Dr. Hollen knew exactly which chemo drugs I needed and the best treatment plan for me. I believe his background pharmacology makes him the best oncologist, bar none. I am now almost eight years cancer free and I feel fantastic. Dr. Hollen always makes me feel like I am his only patient when I am in his office. He’s very comforting and supportive and I feel safe having him as my doctor. I just love this man."

"He’s been my dr for 24 years. Love him. Great bedside manner and listens. Cancer free for 24 years due to his care. Highly recommend!!!"

"Great oncologist!! He is very knowledgeable about general cancers- He gives personal care to patients. He was a pharmacist before he was a doctor, so he knows more than most doctors about pharmaceutical treatments available."

"My wife and I recently moved to the OKC area and my wife started to go to Dr. Hollen for follow up visits to monitor remission from lymphoma. I have gone with her on a couple of visits and have asked a number of questions. He is very patient and respectful and is willing to discuss our questions. Through our conversations and his follow up, he was able to diagnose a condition that other doctors and specialists had missed for 12 years! He is very knowledgeable and compassionate. I highly recommend him."
