I interviewed three doctors who were highly recommended but found them and their office staff and system to be cold and impersonal. Then I found Dr Alcantara. He let me talk, he listened, asked questions, didn’t rush me and made me feel that I mattered. A colonoscopy can be a scary thing but he and his staff were so caring and considerate that I recommend no one but Dr. Alcantara for tests or treatment.

He assured my dad that his surgery would be simple,the tumor is so small I'm only taking out 1/4in you'll be back to normal in no time. Not true,He got an infection caused by Dr.a not giving him a cleanse b4 surgery which had him in ICU in a coma for 3 week's.was horrible with postop when he did come hme 3 mnt after surgery.Till this day my dad can not control his bowels & is humiliated always. there's nothing any dr can do, since Dr.a cut out to much of his rectum. Please get a 2nd opion

Mario has been my wife’s surgeon through two surgeries. We have never met somebody who cares more or is as competent of a surgeon. We would like to keep him a secret for just our needs , however that would be wrong. I would recommend his services to anybody that needs the best!

He has an incredible knowledge base & great bed side manner. Not always easy when dealing with Stage 4 Colon Cancer but somehow he gets me through. I would and have recommended my family members to him to get screened!

Doctor was great, but receptionist/staff horrible. Not sure who dropped the ball, but was never told or given information on cream the Doctor wanted me to use. I knew I had to buy the fiber but thought the cream was prescription. & the office has absolutely NO concern for my privacy as a patient. The office needs to take OSHA/HIPPA class before one of the patients, who is not as passive about this matter as me,takes this matter further than an online review. Missed work and $100 my copay wasted

Dr Alcantara was extremely professional and took the time to answer all my questions and concerns. Would highly recommend him. Traci was excellent in explaining all aspects of the prep for my surgical procedure.

Very pleased with Dr Alcantara's skills but not support staff as they had me wait over hour just to schedule colonoscopy then messed up date and failed to send in prep prescription and had to reschedule

Dr Alcantara did great work in me. Performed surgery to remove a piece of colon diseased by diverticulitis. And fixed other linked issues. He is also very down to earth, compassionate and funny.

I met Dr.Alcantara when my husband needed an appendectomy. He did an excellent job in a difficult case and he has been very kind to both of us. I was especially grateful that he was responsive to my need for a colonoscopy based on my family history... Much more responsive than I have found in other physicians. He is a very fine doctor in my estimation.

Worst experience. I thought I had hemorrhoids, but he told me that it was not a hemorrhoid and feared it could have been cancerous. He put notes all over my chart stating that it was a hemorrhoid knowing that he told me it was not. I dish out almost 1000 then I get another bill for more money because the doctor did coded it as a hemorrhoid but the procedure was not a hemorrhoidectomy. The doctor knew from the get go. And now I have to pay additional dollars. Horrible
