Meeting Dr. Diego Marines, first time, very nice Doctor, with his assistant, talking about my abdominal pain, I am so glad that he examined my abdomen because some Doctors do not examine your abdomen so maybe that is why he takes longer with each patient. We were discussing some points and at the end I agreed to watch carefully what I am eating before starting any treatment.

Dr Marines was referred to me as an innovative physician and I think he is exactly that. I will not know fully know until some time has passed and he follows through with his plans, but I was impressed with him.

In my case, I had mention to the Dr bout my anal wart and skin tag, in addition to some other bump that wasn't in my anal lining. He mentioned it was just a skin tag. Later, when I asked him if he could pop or burn the anal wart he said yes. So when he went back to do that, he noticed that I had a fistula. Which he then says "oh good thing we went back and got a second look" which I don't have a problem if he misses it but I had known that he didn't check that part when I had brought it up to his attention. So I would say to do better at listening to your patients.

I had a sudden diagnosis of colon cancer. It created various complications. However, Dr. Marines worked well with a team of doctors to bring me to health. He consistently treated me with great kindness,compassion, always informative, eager to answer questions.

I do not recommend at all. He is arrogant and not knowledgeable. Unfortunately seems like you need to go to the medical center.
