The experience at this center is excellent! The minute you come in you’re helped and acknowledged in a timely fashion. Staff is great from reception to all the nurses. And off course Dr. Askin is absolutely the best, with great bedside manners.

You're Not Too Young: Why Colon Cancer Screening Matters
Colorectal cancer is increasingly affecting adults under 50, making it a growing concern among younger populations.
Dr. Rosenthal explained everything so thoroughly and made me feel completely at ease before my first colonoscopy. I was very nervous going in, but I’m so glad I did it. From start to finish, the experience was excellent. The nurses, anesthesia team, and Dr. Rosenthal were all incredibly kind, patient, and reassuring. I especially appreciated how clearly everything was explained and how comfortable they made me feel throughout the entire process. I’ve always had a difficult time with blood draws and IVs, but the nurses were amazing — I truly didn’t feel a thing. Their compassion and professionalism made such a difference. Thank you to Dr. Rosenthal and the entire staff for such a positive experience. I highly recommend them.
