    I've been seeing Dr. Buch for almost 20 years and I had six or seven gastroenterologists in the 10…read moreyears before that. I saw him again this morning and couldn't remember if I'd left a review about him before so I'm rectifying that now. There are so many reasons why I would recommend him so highly, but here are just a few: He's extremely caring and he pays attention to your questions and concerns. There are very few doctors who do that today but he has been like this from day one. He's kept my gastrointestinal condition under control for many, many years and when I have a flare-up, he always makes a great suggestion that gets rid of it quickly. He spends time with his patients and does not like to be interrupted when he's talking to them, which is extremely rare these days. He makes suggestions about supplements to take to help your condition and your health in general. This is the only doctor of mine who does that. He makes colonoscopies completely painless. He is an insanely gifted diagnostician. He has always figured out solutions to every GI problem I've ever had, but it goes much deeper than that. Years ago I had been though several months of specialists who could not figure out what my condition was. Even though his it's not his area of expertise, he asked the right questions and within 5 minutes he'd figured out that it was a severe case of costochondritis. Again, not even his area of specialization, but he figured it out and referred me to another specialist. That specialist was very kind but could not figure out how to cure it, but I found another professional who eventually cured it. The last time I came in I had a completely unrelated foot problem and Dr. Buch gave me two suggestions that fixed that problem as well. His staff is very attentive and kind as well. If you ask them a question, they will ask Dr. Buch and he will give a specific answer on what to do for your current medical issue. His years of experience are demonstrable and if he does not know the answer to a question, which is pretty rare, he will find out and have his staff get back to you quickly. He is smart, reliable, caring and so knowledgeable. I would highly recommend him to anyone and the friends of mine who I have recommended to him in the past have always thanked me for it. Do yourself a favor and save yourself a lot of problems by making him your gastroenterologist. My favorite medical professional, because he has earned it.

    I liked him. He was very direct and informative. I felt comfortable talking to him and I knew I was…read morein good hands.

    Dr. Sach and his team--especially Helen--are incredible!!!!! They are comforting, kind, and…read moregenuinely caring. Dr. Sach has an excellent bedside manner and immediately put my parents at ease. My dad underwent a very stressful colonoscopy after his primary care physician found a positive result on his bloodwork. Helen went above and beyond to get him in as soon as possible despite their busy schedule. As soon as Dr. Sach reviewed the results and determined it was a false positive, he immediately let us know. By coincidence, I happened to be on the phone and heard the entire conversation with my parents. As a healthcare provider myself, I was truly impressed by Dr. Sach's professionalism, compassion, and bedside manner. My mom and dad have not stopped talking about how wonderful the entire experience was. I highly, highly recommend Dr. Sach and his office. Thank you for taking such great care of my family.

    I just had my first office appointment today as a Crohn's patient and found the office very…read morehospitable and calming. All the front office people are very kind and helpful, Dr Sach is very patient and professional and has a very kicked back & calm personality. I was feeling very hyper and wanted to explain a lot of problematic situations, I was experiencing. He eventually calmly got me to listen to some of his concerns and answere his questions about past symptoms. Then he explained what he thought I should consider. And I felt very relieved to meet a very calm doctor.

I guess it's what I called bad luck however the staff is so not accommodating and very unprofessional they think that I should've came in sick so I'm gonna give them 0 out of 10 stars.

Dr. Collins speaks in short, clipped sentences, seeming both rushed and dismissive at the same time. She becomes exasperated if you don't automatically comprehend her quickly uttered sentences. For example, she asked in rapid speech: "Does he sit?" I answered, unsure of her meaning (and wildly uncomfortable after a few minutes of her demeanor) "I suppose he sits before and after school." I thought it was a physical fitness question. Then she said, almost angrily: "No. Does he sit on the TOILET?" I laughed to break the tension, but the entire thing was really uncomfortable. The worst part is that my son grew more and more tense until his eyes were huge, and when she left the room for a minute he said to me, whispering: "She's mean, I wanna go home." In the end, we learned absolutely nothing from the visit. Also, the office staff behaves just as Dr. Collins does, acting as if you are really bothering them. They deal with you in a manner that is incredibly rushed, and they are very bothered by answering any questions. Strangely, we were their first patient of the morning, and there was no one else in the waiting room as we left. I urge you to find someone else with a bedside manner (especially because she deals with CHILDREN, and even as an adult the experience was awful), this visit was overwhelmingly bad in every way..
