If it weren't for Dr.Devlin's care, I might not be alive today. He has a very calming bedside manner. He really listens closely to your concerns, takes the time to answer all of your questions, and does whatever he can to help you.He truly cares about his patients and wants the absolute best possible outcome for you. I have never met a kinder, more competent doctor! I have the utmost respect for him. I can't even begin to cover all of the ways in which he has helped me. I would recommend him to anybody in need of a hematology/oncology specialist. He is the best doctor in his field!

When my brother was diagnosed with pancreatic cancer, Dr. Devlin was the ER doctor. We are very thankful he was the one on duty. Dr. Devlin is dedicated to caring for his patients, both medically and emotionally. He is knowledgeable, works cooperatively with a team to plot the best course of action for a patient, and he listens to patient input during treatment. He is a doctor my brother was willing to trust, and trust in the medical field did not come easily to him. As a family member, we were always welcomed to discuss anything and encouraged to call anytime we had a concern. Dr. Devlin's staff is courteous, efficient, and kind. If someone is seeking an oncologist, I recommend him as one of the best.

Absolutely the most positive, encouraging and amazing doctor I have ever met. He took the time to sit, listen and explain. He valued my opinion and included me into the decision making for the treatment. He made dealing with a diagnosis of cancer tolerable. Five stars in not enough to rate him. He is truly God sent....
