Dr. Marrero has been my moms Dr.for years and she really liked him so when my family and I moved to Florida we all started going to him and we all really like him, too. Dr Marrero is really nice but also very knowledgeable and professional. I am so glad that we found him.

Dr Marrero is THE BEST. He listens and recommends as much natural treatment as possible before jumping right into heavy drugs , surgeries, etc. He also really cares about his patients whole being and not just the immediate issue. And he doesn't rush you out the door. He will make sure you understand his recommended treatment and always follows up on your progress. Four generations of our family depend on him!

My visit to the office was great. They are very professional and kind. I was seen right away after filling out my papers as a new patient. From the ladies at the front desk to the nurse and then to the doctor, I was treated very kindly. The office is very clean and the location is great. I would highly recommend them to others.

As always, Doctor Guillermo Marrero listened to my health concerns and he didn't mind for bringing up more concerns than the ones mentioned at the time of appointment. He gave pertinent advises, took time to explain the treatments and offered several options. He seemed genuine concerned about my well being. I highly recommend him for his expertise and customer oriented skills.

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.
