I recently switched to a new gastroenterologist. I am glad that I chose Dr Samuel F. Castillo. On my initial office visit - back in May - and I was seen almost right away. He was very attentive with my issuesregarding my previous gastro-physician. He viewed copies of my previous tests and medical records.Thereafter, he recommended a follow-up Upper GI Endoscopy. It was done in early September and it was a seamless procedure. He even came back to see me in the recovery room afterwards. He explained his initial findings. My previous doctor never did that. On my most recent office visit, there were plenty of patients to be seen. I was concerned that my time would be brief. It was not! He patiently explained the pathology results and the recommended follow-up. Henceforth, I was confident that I chose the right physician! On a different note, everyone at the office was great as well! Maritza was very courteous with all my initial questions during the transition. Carmen - at the reception counter - is always hospitable. Ruth and Antonia are also courteous.

Dr. Castillo is very easygoing and took his time. I did not feel rushed whatsoever. The ladies at the front desk are fantastic. They are very friendly and I enjoyed talking to them. I did not wait long in the waitingroom or exam room. Overall I had a very pleasant experience and would highly recommend this office to anyone that is in need of a GI.

I enjoyed meeting Dr. Castillo and I thought he was excellent. In fact, since I knew I had a stomach issue I wish I'd gone to him right away. Why is the meeting with primary care necessary? This process is too drawn out.

My initial results from my procedure showed that there was something causing my distress and pain but then the results came back and all the doctor wrote was "negative." There was no explanation about why my initial results supported my painand discomfort, so I am still in pain and discomfort without any explanation. In addition, it took over a month to get my results. The doctor told me to call back in 2 weeks and then they said they'd call me. In the mean time, I am in pain this whole time without any explanation. Finally at a month I got fed up and called and they magically had my results ready but with limited explanation. In addition, when I woke up from my procedure, the doctor was already holding his coat ready to leave which made me feel really uncomfortable. I had to wait 5 hours for my procedure and was patient, so it made me feel uncomfortable that he made me feel rushed with questions after my procedure.

He's a fantastic Gastroenterologist: professional and tries to be considerate if you mention a tight budget for RX when prescribing. Open to questions and great at informing about risks/options and treatment plans. I've had 4 outpatientprocedures that were exactly as planned. I did put 4 star right away about "wait time" if he's in the office all goes as planned. He is a specialist and like all, he can get caught up in the hospital delays. I see this as a sign of a good MD as he prioritizes safe hospital procedures & emergencies with vulnerable patients.

Dr. Castillo was amicable enough but did not seem very genuine but his office staff were great. My issues with him are not so much personality (I can handle that) and why I would not refer him to others is dueto certain things he said that could be taken offensively. Also, in asking how I could change my lifestyle in order to get better, his response was I may have to take pills for the rest of my life. Maybe some people are ok with this but I am not. I would rather figure out what is causing the issue and change things so medication is not a reliance, especially considering I am relatively young.

I saw Dr Castillo with some genuine concerns for my health and was surprised when he didn't even examine me (palpitate stomach or otherwise) based on my complaints. He gave me a generic answers, wrote off some prescription and sent meon my way. No further tests or treatment. I felt uncared for. However his secretaries are VERY nice and kind.

I chose Dr. Castillo for 2 reasons: he has strong ZocDoc ratings & feedback, and his hours are pretty convenient (after 4PM) for working professionals. Upon arrival, I appreciated that he is located at and affiliated with St. Marys Hospital.The facility is not modern and does not have current technology, however there is parking on-site which makes it a somewhat convenient destination (traffic notwithstanding). The receptionist area is filled to the gills with files; you have to appreciate the pleasant employees who endure such a tight space and long lines. The nurses called me back within 5 minutes and asked a lot of questions, some duplicative of the new patient forms filled on ZocDoc. I described my symptoms and they left to let Dr. Castillo know I was ready. About 10 minutes later, he enters the room, has me sit in the chair rather than the patient table, asked me to describe my symptoms, and then gave a quick, assumptive diagnosis solely based on my description. Dr. Castillo said that surgery was the only option if his diagnosis was correct. I then sat on the table, he pressed my belly, there was no pain or sensitivity, then gave his reco and left. It took all of 5 minutes. Needless to say that while I appreciated the speed, I would have preferred a more thoughtful and thorough discussion as I've never had gastro problems nor am I familiar with the surgery or procedures he recommended. I was disappointed that I had to go home to look up what these entailed rather than him taking the time to walk me through these. [To contrast, my primary care physician checked me for the same thing and spent 45 minutes with me, pulling up pictures on the computer to walk me through how the systems work and what the procedures were.] I might continue with Dr. Castillo, I might not. I'm not sure. However I find myself regretting making an eleventh hour gastroenterology appointment on ZocDoc rather than going through my PCP first. Dr. Castillo wasn't a bad physician -- let me be clear. But for a patient like me who needs explanations and descriptions rather than quick observations, this didn't meet all of my needs.

During my consultation, he was too inattentive and dismissive for what I needed. If you want someone to tell you what you need to do and don't want to be as active in your care, I think he'd do pretty welljudging by the rest of the reviews and his training.

Dr. Sam was very knowledgeable and had a great approach to Crohn's disease. After seeing many specialists over the years, Dr. Sam was the only specialist to explain the pro's and con's to several treatment options that have been published. Helaid out a plan to get myself better and feel very comfortable with his treatment plan. The office staff is super nice and I did not wait at all. I look forward to working with Dr. Sam.
