I’ve been visiting this office for over three years.

I’ve been visiting this office for over three years, and I couldn’t be happier with the care we’ve received. Dr. Irias has been seeing my daughter, and I’m truly more than satisfied with the attention, professionalism, and kindness shown every time we come in. The staff is always welcoming, and the overall experience has consistently been excellent. Highly recommend!

Dr. Marco Castillo fue quien tenía disponibilidad más pronto.

(Translated by Google) We've been taking our son, Máximo, to Pediatric Associates Doral since he was born. We needed a pediatrician for his first checkup after leaving the hospital, and Dr. Marco Castillo was the one with the earliest availability. At the time, we thought we'd switch to another doctor we were recommended, but from the very first appointment, we knew it wouldn't be necessary. Dr. Castillo is an incredibly compassionate, dedicated, and kind professional. He takes the time to listen patiently and truly connects with both parents and children. Today, two years later, our son adores him: he hugs him, trusts him, and cooperates in everything thanks to the loving and patient way he treats him. As first-time parents, he has always been available to answer our questions and give us peace of mind. In addition, the office is very clean, and the staff is polite and friendly. Although the wait can sometimes be a little long, it's definitely worth it. We recommend him without hesitation. (Original) Llevamos a nuestro hijo Máximo a Pediatric Associates Doral desde que nació, ya que necesitábamos un pediatra para su primera revisión al salir del hospital y el Dr. Marco Castillo fue quien tenía disponibilidad más pronto. En ese momento pensamos que luego cambiaríamos a otro recomendado, pero desde la primera cita supimos que no sería necesario. El Dr. Castillo es un profesional increíblemente humano, dedicado y gentil. Se toma el tiempo de escuchar con paciencia y realmente conectar tanto con los padres como con los niños. Hoy, después de 2 años, nuestro hijo lo adora: lo abraza, le tiene confianza y colabora en todo gracias a la forma tan amorosa y paciente en la que él lo trata. Como padres primerizos, siempre ha estado disponible para responder nuestras preguntas y darnos tranquilidad. Además, la oficina es muy limpia y el personal es educado y amable. Aunque en ocasiones la espera puede ser un poco larga, definitivamente vale totalmente la pena. Lo recomendamos con los ojos cerrados.

they are open on the weekends.

While I am not pleased the with wait times, I am still giving it 5 stars for the following two reasons: 1) Dr. Christian Irias and 2) they are open on the weekends. Dr. Irias takes the time to listen to the concerns and addresses them all on the spot. There are many times where I have been hesitant on something, but his explanations makes me more at ease of making the correct decisions. It is worth the wait time to see him. I have also had a great experience with Dr. Marco Castillo Ayarza. I am also very happy that they are open the weekends as there have been times where the care is needed and it is much better than waiting or having to go to an urgent care.

my son has regained his trust in medical centers thanks to him.

(Translated by Google) Hello, this medical center is excellent. From the receptionists and nurses to the doctors, everyone is wonderful. Dr. Christian, in particular, is an excellent professional—warm, empathetic, and accurate in his diagnoses and treatments. He has the patience to explain everything in detail to us parents. My 5-year-old son has regained his trust in medical centers thanks to him. He's no longer afraid to go when he's sick and always wants to see him. They also perform flu tests and other screenings there, and they have overtime hours on certain days of the week. Thank you for everything; please don't lose that warmth and empathy. Look at the lovely little gesture they made for my son on his last visit—it brought a smile to his face even in the midst of his discomfort. (Original) Hola, este centro médico es excelente. Desde sus recepcionista, enfermeras hasta sus médicos. Especialmente el Dr Christian, es un excelente profesional, cálido, empático y asertivo en sus diagnóstico y tratamientos y tiene la paciencia de explicar a detalle todo a nosotros como papás.. mi hijo de 5 años, recuperó la confianza en los centros médicos gracias a él, ya no teme ir cuando está enfermo y siempre quiere atenderse con él.. además allí mismo le realizan examen de flu y otros y tienen atención overtime ciertos días de la semana. Gracias por todo, no pierdan esa calidez humana y empatía. Miren el detalle tan lindo que le hicieron a mi hijo en su última visita, le sacó una sonrisa en medio de su malestar

incredibly kind, patient, and always have the best sense of humor.

I cannot say enough good things about Dr. Christian Irias and Doris Aguilar. I have two children, and both of them absolutely love them. They are incredibly kind, patient, and always have the best sense of humor, which makes my kids feel comfortable and safe at every visit. As a parent, that means everything to me. My children don’t want to be seen by any other doctor, only them. And honestly, I wouldn’t change them for anyone else. If they ever leave Pediatric & Associates, I will follow them wherever they go without hesitation. We are so grateful to have providers who genuinely care, listen, and treat our kids like their own. Truly the best.

We left feeling reassured, supported, and confident in the plan he recommended.

We are extremely grateful for the care our pediatrician provided to my daughter during a recent stomachache. He took the time to listen carefully, evaluated her thoroughly, and explained everything with such patience and kindness. What we appreciated most was how attentive he was not only to the physical symptoms, but also to her emotional well-being. We left feeling reassured, supported, and confident in the plan he recommended. Truly compassionate and excellent care.

Viviana C.
