Dr Wendorf, and his staff were excellent.
"The nurses and anesthetist are all positive people." I felt so at ease. Not sure why, I was so scared, they totally made all my fear go away. Love them!

Reviews
I recently had an appointment with Dr. Gancayco and had a very positive experience. He took the time to carefully listen to my concerns and discuss my symptoms in detail.
We talked about my medical history, including my past left kidney cancer and how having one kidney might be contributing to my ongoing vomiting and diarrhea. Dr. Gancayco was thorough and requested additional testing, including a stool sample and blood work, to check for any underlying issues that could be causing my symptoms. He also scheduled an endoscopy to further evaluate the bleeding I’ve been experiencing when vomiting.
Throughout the visit, I felt heard, respected, and genuinely cared for. I appreciate his attentiveness and the thoughtful approach he is taking to find the cause of my health issues. I would highly recommend Dr. Gancayco to anyone looking for a doctor who truly listens to and cares about their patients.
I have been seeing Dr Cunningham for several years. Top notch doctors and former Air Force. Highly recommend.
