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
