#### Doctor Testimonials
Buffalo Surgery Center is all about patient experience in a pleasant and relaxing atmosphere. It is made possible by a surgical and strategic leadership team that focuses on extensive analysis, patient needs and corrective steps that are direct offshoot of experience and knowledge.
Alok Gupta, MD – Gastroenterologist
I’ve been operating at the Buffalo Surgery Center for nearly 20 years and it has always been a top-notch facility with dedicated nursing and operating room staff. Since the opening of our current facility in 2016 and our recent expansion, our team at the BSC has taken outpatient Orthopaedic care to whole new level with increased capacity and enhanced efficiency. But most importantly, the care they continue to provide to my patients is outstanding.
John J. Callahan, MD – Orthopaedic Surgeon
The Buffalo Surgery Center has made it possible for us to bring outpatient joint replacement to the people of Western New York, which has already made a huge difference in the lives of so many people here in our community. The BSC is a state-of-the-art facility that is staffed by some of this area’s most skilled and dedicated medical professionals. They provide superior care for all of my patients and create an environment that is a real pleasure to work in.
Nicholas J. Violante, DO – Orthopaedic Surgeon
I can’t say enough about the Buffalo Surgery Center. The facility itself is state-of-the-art, with everything I need under one roof. And the team is outstanding. Top-notch medical professionals who are committed to providing my patients with excellent care. The Buffalo Surgery Center has helped me and all of the Buffalo Medical Group’s Gastroenterology and Colon & Rectal Surgery providers to achieve the “triple aim” objectives of healthcare reform – improved patient access to care, exceptional outcomes and lower cost.
Joseph Leberer, M.D. – Colon and Rectal Surgery
#### Patient Testimonials
My whole experience was wonderful! Everyone was friendly, funny and explained everything. Thank you!
From the moment I walked in to the moment I left, I felt at ease. I do not want surgery again, but if I did need it, I’d want the crew at BSC to be there for me! Thank you!
This was the best experience I’ve had over the years, in having any procedure done anywhere! A special thanks to Katie, the nurse who put the IV in before my procedure. I have problems with even getting regular blood draws – she was outstanding. No pain, and nice too.
The staff members are on top of their game – such professionals! Thank you – the follow-up call was much appreciated!
