Dr. Marinier is the best. He listens, understands, and is compassionate. I will always request him as my Dr. Both my husband and I feel very fortunate to be under his care. He has helped us many times and is a blessing in our lives!

Yes, I've been going to Dr. Marinier since he's been coming to La Cross. I don't know how many years ago that was, but I was one of his first patients. And Dr. Marinier is one of my favorite doctors. I can't say how wonderful he is. He's very patient, very kind, very understanding, and I wouldn't want to go to any other oncologist. So he's just the best doctor I've ever had, and I just love him to pieces, and thank him so much for being my oncologist.

We only see Dr Mariner once a year. He always takes time to review the past year to see how things are going and never tries to rush the appointment,
