Patient Testimonials

"I don't have enough time and/or space to talk about why this place is amazing. I just had my very first colonoscopy done here and I was a bit nervous. They put me right at ease. From the nurses to the anesthesiologist to the doctor himself I could not have been more comfortable. The whole experience was quick, smooth, and easy. Highly recommend!"

"Dr. Asamoah and team made my EGD procedure very comforting and wonderful. From start to finsih her team made me feel safe and that I was in great hands. They're all so kind, heartwarming and professional. Last thing I remember before knocking out was Dr. Asamoah infectious smile and kind words that put me at ease. I found my forever GI! I highly recommend this place. :-) "

"My procedure (colonoscopy) owent smoothly. The staff was professional. I was in and out in less than 2 hours. I arrived at 9am waited in the lobby to be called to the back. Then was prepped and I was out by 11 in my car. I would definitely recommend Dr. Vivian Asamoah and Zazen Surgery Center."

- F. Taylor

"I recently underwent a colonoscopy/endoscopy procedure at Zazen Surgery Center. Throughout the entire process, the staff consistently checked in to ensure I was comfortable. I arrived at 7 am, and by 9:30 am, I was already on my way home. After the procedure, the staff provided clear instructions for my at-home care. The combination of a friendly and professional staff, a focus on patient comfort, and the impressive efficiency of the procedure made the entire process not only smooth but surprisingly bearable."

"Great experience and would highly recommend Zazen Surgery Center to all my family and friends. The front desk and procedure room staff are all attentive and caring and made me feel at ease. I was in and out of there in no time. It was a such good feeling when Dr. Obuaya, my anesthesiologist, talked to me first before the procedure. Dr. Asamoah did my screening, and she is also superbly wonderful informing my daughter of my case. Two thumbs up for the doctors and staff."
