Paul and Dr. Caldon go way back, but we were lucky enough to snag him over seven years ago!  He has worn many hats in his journey with High Peaks Dental and has fallen into his nitch in accounting.

He retired from the Air Force  after 22 1/2 years of service. Paul decided to stay in Plattsburgh because it is very similar to his hometown in Indiana. 

Paul attended Logansport High School, Los Angeles Mission College, University of Maryland, Boise State University Parkland College and Community College of the Air Force. This explains his trivia knowledge! While in school he focuses his studies on Criminal Justice and General Studies.

Paul married his beautiful wife Kim over forty four years ago. Together they have three children, and are grandparents to four grandchildren. Paul always looks forward to the family reunion held at the "track" in Saratoga and attending performances by the Grand kids.

When Paul isn't betting on the races he enjoys testing out new BBQ recipes and traveling with his wife. His ultimate goal is to live long enough to take his wife to Sicily. 

The most rewarding part of working at High Peaks Dental for Paul is working behind the scenes to make sure our patients have the best possible dental care.
