Bad experience. Since I answered the doctor's questions on how I was doing they tried to charge extra because we "discussed issues beyond the annual exam". Ridiculous. Terrible staff.

Dr. Marreeo is my own and my husband's personal primary care physician for many years. He is a caring person whose bedside manner is that of the small town family doctor we went to as kids; he is friendly, takes good care of himself and his patients and sees them in a timely manner. (I do not expect ANY doctor to see me on the dot of my appointment time, by the way, as on any given day, some patient's needs will be greater than others.) Dr. Marrero requests that his patients have the their labs done prior to each visit. Based upon their results and the patient's symptoms he either treats their condition, provides excellent referrals, or sends them on their way with a clean bill of health. He is a thorough doctor who carefully checks each patient's current medications, and always takes the time to make sure I'm happy and doing well before I leave his office. If not, he makes appropriate and thoughtful recommendations. As any family doctor these days, his time is limited, but after all these years, I wouldn't change him. He's a good and caring person and doctor.

Un excelente médico con calidad humana y valora lo que sus pacientes refieren antes de recetar. Sinceramente, mi experiencia con la medicina aquí en la Fl Central no ha sido buena, excepto con este profesional.

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!

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.
