His office is very presentable. His staff is courteous. If Spanish is your 1st language this office is highly recommended because the staff is bi-lingual. Dr. Marrero is a great listener and therefore, had great recommendations. He ordered what was needed to rule out my symptoms & concerns.

Availity insurance eligibility check was not good. They made me wait and call the insurance company back and forth because billing department had billed for an incorrect billing code for my previous visit and had declined my office visit.

The Doctor was very nice, he was patient and answer all the questions. I wish he did more direct recommendations instead of always saying to do whatever I think is best about my treatment. One of the nurses was somewhat rude and seem very rushed, I express my concern about the changes in my blood pressure and she gave me a piece of paper and told me to take my BPs every day, record them and bring them to the next visit..did she assume I can take BPs? What if I didn't know how to?. Also I was not told that I was suppose to be fasting for my lab tests. Later, when I called to ask if it was ok if I was not fasting, a nurse told me, that everyone knows that labs are always fasting, and if the doctor doesnt say anything I suppose to know that I have to fast before labs... she said the Doctor would only clarify when it is ok to eat. I felt very silly, I have had done many lab test in the past that did not require fasting.

the staff is hit or miss. First time I went everyone was nice. Second time no one greeted me the girl that was nice before purposely ignored me. The tech taking my stats was horribly rude with the worst attitude. I brought to her attention her issues and she said she doesn't let things bother her. Her rudeness to me and my Pointing it out "got to her." This female was Hispanic young and just disgusting. I never want to be in her nasty presence again she was a joke to deal with. No one was friendly just the rudest staff ever. The doctor is terrible. I can't get into the things she did but she is incompetent and awful. Many of my relatives are doctors and I know a good doctor. This doctor was just awful and kept trying to send me to a specialist for stupid reasons. She finally did testing on me and found something. My relatives were surprised at the way she prescribed meds and how incompetent it was for the days and the dosage. She had a bad attitude and I will never return to this awful place. Only good thing is the short wait time.

I am new to the area so finding a good doctor was one of my top priorities. Although I was nervous for my first visit, the staff at the front desk were nice and truly welcoming. Dr. Marrero was a great listener, asked questions and worked with me to come up with the best options for my concerns/needs. You can tell he genuinely cares about you and your health. I was very pleased with my first visit and would definitely recommend him to anyone seeking a physician.
