I can’t say enough positive things about this practice. I’ve suffered from GI issues my entire life. I have been repeatedly subjected to the same useless, expensive diagnostics to no avail. Dr. An has done more to help me in 7 months than all of my other GI docs combined. Foremost, he listened. Actually listened to me which was a first. Then, he prescribed non-invasive testing (covered 100% by insurance) which I never knew was even an option. Upon my diagnosis, he prescribed a medication that was not covered by my insurance ($680 worth). My pharmacy called to break the news and told me she alerted Dr. An. Within an hour, I received a message saying they contacted my insurance and my prescription was now covered at 100%. I have never had a doctor take care of things so expeditiously. I am beyond grateful
Keep up the outstanding work!
I was very pleased from the start to the finished. Everyone was very good and i has total trust the whole time. I felt like I was treated special but I feel like everyone gets the same very good treatment.
Very Professional Practice!
I was really anxious before my procedure. The whole staff from check in to check out were very understanding and put me right at ease. The procedure was so easy and the team was very efficient!. I would highly recommend GI North, the staff, and Dr. Sergio Quijano to anyone needing a good GI practice
Thank you all!
Tracy greeted me right away with a lovely smile. Her warm personality, caring professionalism and clear instruction made my experience very positive the day of my colonoscopy. Anyone who receives her nursing expertise is lucky indeed. I would also like to say that the entire staff was very pleasant and the procedure went smoothly. Dr. Cofrancesco made me feel relaxed in his capable hands, with clear and patient explanations.
Thank you, Dr. Cofrancesco!
I had my follow up yesterday with Dr. Cofranceso, and I wanted you to know how much I appreciated the thoroughness of every step in the process of my appointments and interaction with the staff. I have been very impressed with Dr. Confrancesco's bedside manner and explanations of the findings on each of my procedures. I am grateful to him and the lovely staff at GI North.
Thank you, Dr. Cofrancesco!
I want to thank you again for providing such a wonderful and painless service. In my book, you’re the best! Thank you so much.
