“I can’t believe that I am even admitting to this, but I went to see Dr. Nowain for hemorrhoids. I know that they are pretty common but it has still been an embarrassing topic for me. Before I ever had problems with hemorrhoids, I only thought that senior citizens got them. But, I was definitely proved wrong. After a few years of on and off constipation, plus a job where I sit down for most of the day, I was plagued with this annoying condition. I wasn’t sure if I should go to my general doctor or if I should see a specialist. After talking with my sister, who is in nursing school, she suggested that I see a gastroenterologist.

“So, I started to search online and came across Dr. Nowain. His website was really user friendly and helpful so I decided to call his office to see if they could help me. When I spoke with the receptionist she was very understanding and friendly. I was nervous to admit that I even had a problem with hemorrhoids but the receptionist assured me that there was nothing to be embarrassed about. I was so pleased with our conversation that I decided to make an appointment with Dr. Nowain.

“When I got to his office, on the day of my appointment, I was impressed with how professional everyone was. The entire staff was so nice and they seemed like they all genuinely cared about the patients. I didn’t even have to wait that long to see Dr. Nowain, which was really great, considering my level of anxiety was so high that day.

“Dr. Nowain was so incredibly patient and personable that he instantly put me at ease. He really does have the best bedside manner! Well I won’t get into the details of my exam but he did this new banding procedure that was almost like a rubber band. It was actually kind of cool, he showed me how the entire procedure would be done before hand, I even came home and told my sister about it! It did not hurt at all and the hemorrhoid just fell off after a few days just like he said it would.  Amazing to finally feel relief!

“Dr. Nowain told me that almost every adult deals with hemorrhoids at some time in their life which made me feel much better. I wanted to leave this review on yelp in case there are others out there embarrassed like I was. They should know there are options and nice doctors who can help you. I feel so much better now and I know that if I ever have any problems in the future, Dr. Nowain will be able to help me. Thanks Dr. Nowain, you’re awesome!”

— Robert Z

“I was referred to Dr. Nowain from a friend of mine. I went to see Dr. Nowain because I developed an external hemorrhoid shortly after my pregnancy. I was feeling a lot of discomfort and experiencing blood in my stool. I never experienced anything like this before and the whole thing scared me a bit. After a meeting with Dr. Nowain, he really made me feel at ease. He explained to me that it’s actually quite common for women to develop hemorrhoids after pregnancy because of the increased pressure. He treated me with prescription strength creams as well as instructing me to take baths with Epson salt. I am 100% better now and it’s all thanks to Dr. Nowain. I am so thankful for his kindness and help, I highly recommend him to anyone!”

– Katie

“Dr. Nowain is one of the most attentive and patient doctors I’ve been to. He is not only incredibly personable, but he makes you feel comfortable and goes out of his way to make sure all of your questions and concerns are taken care of. In addition, I moved to another city and he personally called my new physician to explain my medical history and made sure I was going to be in the right hands. I highly recommend him.”

— Heather N

“I couldn’t have chosen a better doctor! Dr. Nowain clearly knows what he is doing and talking about and he showed a genuine interest and concern about my medical issues. He’s very caring and has an extremely receptive staff as well. Highly recommended!”

— Luciana F

“My experiences with Dr. Nowain have been nothing short of excellent. I found Dr. Nowain via the internet when I was searching for a doctor to treat some hemorroid symptoms I was having. After my initial visit, I knew he was the right guy! Very knowledgeable, asks excellent questions and very thorough in his explanation of treatment options. I wasn’t happy about having to go through the hemorroid banding procedures, but he and his staff made it worth the anxiety and effort.

“He also mentioned that I ought to consider a colonoscopy when I turn 50. I would go to Dr. Nowain for sure. As it turns out, my wife’s regular phyician recommended a colonoscopy screening for her. I suggested she meet with Dr. Nowain. She was as impressed as I had been, and he performed the procedure on her without any complications whatsover.

“His staff is very friendly and quite helpful in all regards. I would highly recommend Dr. Nowain to family and friends for any/all GI issues, and the hemorroid treatments as well.”

– Bob B (from Yelp)

“I had some intestinal issues and other doctors had told me that I need a colonoscopy and an EGD. The thought of this was very scary and I kept putting it off, until a friend recommended Dr. Nowain. She had her procedure done with him and said that he made it very easy.  She was right! He did a great job of explaining everything and made sure that I was comfortable. Doctors like Dr. Nowain are hard to find these days.”

— Eva S

“Dr. Nowain is very thorough and he’s seems genuinely concerned with my overall health. The staff is extremely courteous, competent and friendly. One of the best experiences I’ve had at a doctors office.”

— Frank

“Dr. Nowain was extremely caring, thorough, and patient. He listened to and solved my problems. I did not have to wait long to be seen and his front office staff was very efficient and friendly. I highly recommend him if you have any GI issues.”

— Kris R

“It is always great to find a doctor you like and especially one who takes time with you (I was worked in) and is caring. I certainly will recommend him.”

— Laurie B

“The most efficient and thorough doctor appointment I have ever been to.  Lovely reception area with a friendly (and smart) staff.  Dr. Nowain actually explained what was happening, so I understood and was able to ask questions.  And for someone who hates needles…I barely felt a prick!  Highly Recommended!!”

— Arash S

“Dr. Nowain is a kind, professional, and extremely knowledgeable Gastroenterologist.  I feel comfortable going to him, and recommending him to others.  He really takes his time with his patients, and I felt like he gave me more attention than any other doctor I have been to in years.  It is nice to see a physician understand that patients are people too, and his infliction of “service” into a medical practice is refreshing.”

— Dolores G

“He was willing to return a frantic weekend-emergency call right away from  a girl he’s never even seen before… That says a lot about his character.

Although, when I had previously tried to make an appointment, they were booked for the next couple weeks, he let me know in (one of my many) moments of panic, that they would make time for me.

He’s willing to answer the same questions over and over, and he also has a sense of humor – which i think is totally necessary for someone who’s inspecting your rectum.”

— Laura S

“Dr. Nowain is the best doctor that I have ever been to. He is very helpful, understanding and truly cares about you as a patient. His staff is always friendly and welcomes you into the office. I had to have a few procedures and he always walks you through them before and after. For your follow up visits he makes sure you completely understand what’s going on with your results. The most thorough doctor I have ever had!”

— Christopher N

“Dr. Nowain is my hero! I do admire Dr. Nowain’s knowledge and honesty, especially when no other doctors were able to diagnose my illness. Thank you to Dr. Nowain, and I wish him and his family the best.”

— Tina

“I don’t usually leave healthcare reviews (unless I want to warn others of bad experiences) but in this case, I must say this… If Ari Nowain is not your Gastroenterologist you’ve got the wrong doctor. This guy is the most knowledgeable, easy to talk to, pleasant doctor one could want. Especially when it comes to the kinds of sensitive issues he is dealing with, he makes you feel comfortable discussing issues and provides detailed explanations of his recommendations. His staff is very nice and Layla at the front desk knows her stuff and is a real professional. I had two procedures performed by Dr. Nowain that I initially was very anxious about having done. He was very reassuring and I felt secure that I would be in good hands. In fact, it was such an easy process and overall Dr. Nowain made it seem like a walk in the park. I highly recommend this doctor particularly if you are squeamish about intestinal issues. No need to be embarrassed or nervous with Dr. Nowain.”
