Patient Reviews
Aug 22, 2025
I wouldn't consider going to another Dr. or practice. I was referred to Dr. Showalter at least 15 or more years ago and am glad I was. The whole staff and process is seamless from checking in all the way until they're finished. The old days of waiting in the office and spending a whole day there is gone! Most importantly is how proficient Dr. Showalter is! From the results of a blood test and a low but edgy PSA count, he saw a need for further testing. I had gleason 9 Prostate Cancer, but because of his proficiency it was removed and I have now been cancer free for almost a year! Thank you Jesus for Dr. Showalter!
