Dr. Alcantara is great. Very straightforward, humorous, and effective. He knows what he's doing. The office staff, not so much. I had one of the first appointments of the day, and still had to wait over an hour to be calledback. They lost all of my records since my last visit, and I had to fill out a whole new set of forms. And some members of the staff don't talk to the others - it seems they purposely avoid one another, and won't lift a finger to ask that one extra question that could save you a lot of time - the receptionist in particular. She just blames the rest, and can't be bothered to find things out. But Dr. Alcantara is worth the wait. I just wish the front office staff understood customer service better.

Very professional, answers all questions, treated me with dignity and was very sincere. I trust this doctor very much (difficult for me to do easily). I wish he could also provide PCP because I would be extremely satisfied. His staff is nice, professional, and prompt. No time wasted here!
