“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

“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

“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

“I go to Dr. Mehdizadeh and have been in love with everything about him, his practice and his services ever since my initial visit.

He is professional, funny, easy going and really helps identify with my problems and helps me come up with the right treatment options that are tailored to my needs.

I cannot recommend him enough!”

– Kellie R.

“The nurses were friendly, compassionate & helpful. Loved them!”

Colonoscopy Testimonials from La Peer’s Top Surgeons

In honor of Colorectal Cancer Awareness month, some of our top surgeons and doctors at La Peer Health Systems underwent their colonoscopies together. This event was dubbed “Scopefest,” and involved the physicians gathering for their colon prep the night before the procedure, and then for their colonoscopies the following morning.

Below are testimonials from our doctors who underwent the procedure at La Peer Health Systems. Each colonoscopy video contains a testimonial from one of our world-renowned La Peer surgeons and physicians.

“My husband and I both had our colonoscopies here and had a very good experience. The staff was very friendly, and greeted us with smiles and a positive energy. My OR staff and anesthesiologist were wonderful. They made us feel safe and comfortable. We woke up easily with no nausea or vomiting, and was offered water and oreos. I’d recommend this facility for these types of procedures.”
