"Waited a couple of months to see Dr. Root. Once there I was treated with respect and compassion. Dr. Root was absolutely fantastic. Wonderful bedside manner. He had reviewed my prior history and explained things about my past surgery that I was not informed of. My procedure was then booked 2 1/2 weeks out. He and his staff were professional and thorough. I finally have a Doctor that I trust completely."

Friendly, answered nervous questions more than once and did it with a smile, the folks behind the scene s helped me to be relaxed with providing me information and answered my questions.

"I had a fantastic experience with Dr. Singh. Her office was able to accommodate me for an urgent issue to be seen within 24 hours. Her diagnosis was accurate, she prepared me for what the next week would look like, and prescribed a medication, which helped almost immediately. While everything played out exactly as she said it would, she had also provided me with a way to reach her directly and the plan for next steps in case the issue did not resolve. She was professional, kind, and is exactly the type of doctor to whom I would send a friend without hesitation."

"Dr. Root has been such a help to me. After years of frustration GI doctor visits where I felt the doctor did not care about my situation and prescribed the bare necessity to treat the pain and not the problem. After switching over to Dr. Root I have been met with such kindness and help with my problems. I feel that he is a doctor that really cares and spends time with his patients and listens to them and their needs. He’s gone above and beyond with helping me with my issues. Thanks Dr. Root!"
"This was not my first procedure with Dr Fern, he always makes you feel like family, the entire staff is amazing. I always feel safe, assured and confident when I am in their care.

"I just returned from a colonoscopy with Dr. Singh. This is the second procedure I have had with her and I could not be more impressed with the level of care given by her, the nurses, the CNA and the nurse anesthesiologist. From the pre-registration procedure to check-in to pre-test and post procedure, it was efficient and as pleasant as a colonoscopy can be. Every step explained along the way by friendly and professional health care providers. Highly recommend."
"Dr Thyssen and the surgical staff from AEC were very efficient and worked together as a very pleasant team. I would have given 5 stars except my phone call to SIG a week before the colonoscopy almost made me cancel. I called SIG to get a better clarification as to the pre-colonosocpy diet. Whoever I talked to seemingly got annoyed with me asking questions and I was told to stick to no seeds or I they wouldn't be able to do the procedure. How does anyone know they consider bananas to have seeds unless it's clearly stated. I found a diet sheet online from a credible university and followed that. Please include a diet sheet for patients to follow - people's interpretation of peel and and seeds vary. AEC didn't call me until the day before the case to pre-register me. For those two items I'm knocking off a star but the surgical team were the best."
"Dr. Weinstock kept me informed, both before and after my procedure. Letting me know what to expect prior and talking through the results afterward, including what would be next."

"Dr. Singh thoroughly explained what was involved with my procedures including risks and potential complications. She was very easy to talk to about my concerns. Procedures were performed effectively and efficiently without any problems. I am very satisfied an would recommend her for her expertise."
"Clinical excellence + compassion and genuine caring wrapped up into one human being is the best way I can describe Dr. Thyssen. He is a skilled GI doc who listens, asks questions and works with you to make sure you are getting great care. I am a nurse and really picky about the doctors I choose for myself and my family - Dr. Thyssen is fabulous!"
"Doctor Root was Awesome today. I was shooting on see my mom & sisters doctor Aman Singh but very busy. I chose first available and It worked out. Dr Root is a young guy to keep an eye on me for the rest of my life. Things happen for reasons. Since I couldn’t see Dr Singh I got Dr Benjamin Root and I’m happy. He will be my doctor thank you."
