I started practicing in Sioux City with my father, Richard Reinking, and had the privilege to work with my grandfather, Dr. Max Reinking, for a few years before he retired. Now I have the chance to work with my daughter, Dr. Amber Wisner. It truly is a dental family. I enjoy all aspects of the dental profession. It is a pleasure to keep up to date with new technology and techniques. My favorite part of dentistry is working with a great staff and great patients who make my day a joy. I enjoy working with all ages and enjoy creating a relationship with each and every one of them. We try to treat everyone like family.


I attended the University of Nebraska for my undergraduate degree and continued on to the University of Nebraska Dental School where I received my Doctorate of Dental Surgery in 1973.

Continuing Education

I enjoy the continuing education aspect of dentistry and I feel I never can learn enough. I have recently been involved with the Scottsdale Dental Center under Dr. Frank Spears, learning about full treatment planning especially in the areas of aesthetics. Everything I have learned has helped me in helping my patients reach their goals for full mouth care.
