I keep trying to write Dr Jacoub the most glowingest review ever written and I keep getting flagged and removed so I’m just going to keep it simple this time and say I absolutely LOVE Dr Jacoub. He is warm, kind, compassionate, genuine, and I feel like I am in the best hands. I’d recommend him to anyone who needs a hematologist or oncologist for any reason. Best doctor I’ve ever seen for any reason!

Dr Jacoub was so kind and attentive and asked lots of questions to help create a plan. He seemed like he truly cared about me and my health and my needs. He patiently listened to everything I had to say, he answered my questions and had new ideas my previous doctor didn’t have, which I appreciated. He was understanding that I like to be educated on my options and choices. Dr Jacob is a very nice, kind man and I feel very confident being under his care.

Dr. Jacoub is something that surpasses the mere title of M.D. He actually listens; he truly tries to understand each patient, individually. He doesn’t only treat conditions or disease; he treats the person as a whole, with compassion you simply cannot teach. Dr. Jacoub has this one in a million, ability to calm your nervous system so that your body can ready itself to start healing, even before treatment or medication begin. These types of doctor’s are the rare ones you really need to have on your team for the best success. You need at least one on your team. He’s a restoration of hope, when so many can sadly add to the stress of multiple diagnosis with lackluster bedside manners. Get yourself a doc that can do both, like Dr. Jacoub. An excellent doctor; master of his field AND a truly caring human being; that gives so much respect to the matters at hand and never diminishes concerns. One in a million. My husband and I are both patients of his and we don’t go a single appointment without gushing over how incredible he is after. Oh, and did I mention his staff is incredible too? Zero wait. Super kind and helpful. Beautiful office and building. A cut above the rest. I know I must sound like a paid reviewer. Absolutely not. He’s THAT incredible. We literally won’t move out of driving distance from him. He’s THAT good.

Dr. Jacoub has been my oncologist for 8 yearsDr Jacoub explains my treatment in a way that I can understand. He is warm and kind (and handsome too). His staff likes him and that is an indication that he is respected, not just by his patients, but by his employees as well. Bottom line- I felt cared for and in capable hands.

Dr. Jacoub is so kind and patient. He doesn't rush you and takes everything you're going through into account. He's very thorough. Other doctors I've worked with will only listen to symptoms regarding the organ they are treating, and disregard any other symptoms you may have as unrelated, which can them to miss the bigger picture and misdiagnose or underdiagnose.

The provider was over an hour late to the call and it was difficult to get ahold of the different locations he works. During the visit it seemed rushed and I did not have as extensive of questions and answers due to the video connection. I also was supposed to get lab orders and never got the information to schedule them.
