What People are Saying
"Great experience. Very knowledgeable and friendly staff, excellent customer service. Dr. Schub was excellent, answered all questions and never rushed through my visits. Highly recommended."
"I've been visiting Dr. Schub for years. I have never been dissatisfied whether it's an office visit or colonoscopy. The office is great! Dr. Schub is very personable and explains everything very well. The colonoscopy procedure is great! The staff treats you very well while preparing. No pain, and great after care. I highly recommend this practice!!"
"It has been 10 years"
"Just saw Dr. Schub's page as a suggestion on here. It has been at least 10 years since I saw him and he did the best thing a doctor could do. He did the EGD down my throat. I was out, so I had no issues remembering a camera going down my mouth. We found the issue and fixed it. I've not had to see him again. That is how it should be. I shouldn't need years of follow up, but I know I'd go right back to him if I ever had an issue again."
“High Quality Care”
"A high pressure career resulted in several significant medical problems prior to my retirement. Thanks to Dr. Schub and his outstanding staff, these problems were diagnosed early, resolved and monitored regularly, leading to my thoroughly enjoying retirement over the last 8 years. While EGD's and colonoscopy may not be the most enjoyable experiences, I'm extremely grateful for the extremely high quality care I've received."
