"I have recommended Dr. Douglas Adler to friends and recommend him to anyone reading this review. Dr. Adler analyzed my issue and prescribed medicine that has kept me me remission for decades. When I need a colonoscopy Dr Adler is on time, upbeat and most importantly thorough with the procedure."

"Dr. Adler is a genuinely nice person and did a great job of explaining things to me. Excellent doctor! He really knows his stuff. Everyone working at his office is super nice and polite and most importantly competent. Considering we have been going through a pandemic, I give them extra kudos and also to the folks at the Glen Endoscopy Center where I had my colonoscopy. Everybody was so professional and efficient and kind."

"I was having my first colonoscopy and Dr. Adler and his team did a great job. I felt his was very delicate with his examination and explanation of the procedure and then executed with perfection. I’m a very happy patient with my results! Thank you Dr. Adler and team!!!!"

"This was my first colonoscopy experience, but at 57 I knew I needed it done. I had some trepidation going into the whole process, but mostly uncertainty. But after leaving Dr Adler's office I was pretty amazed at how easy it all was. From the time I walked in to a warm and genuine greeting from one of the nurses (I think her name was Jackie) to the time I walked out a couple of hours later, it was stress-free, painless, and comfortable. Including the front desk person and Dr Adler I believe there were five people I interacted with during the procedure. Each of them was very helpful, making me comfortable and putting my mind at ease. When I was brought into the room for the procedure, the nurse anesthetist (Nikki or Nicole) explain what she would be doing, and after administering the anesthesia I think I was out within 30 seconds and "came to" after a very deep and satisfying sleep. There were no complications during the procedure, images were shown of a few polyps that were found, and I was told that I would get news of the test results soon afterward. While some people have reported being a bit loopy afterward, I felt no odd side effects and had a pretty normal day from there on. They asked if I wanted a follow-up "well-being check" which I declined, since everything had gone so well. The office did follow up with a phone call with tested results in a reasonable time. In summary, my experience with Dr. Adler and his staff was really "first rate.""
