Tom Dickson

About Dr Tom Dickson

Hi, my name is Tom Dickson. I originally grew up in a small community of Liberty in northern Utah, so small we didn’t even have our own zip code. I was a child number four out of 10 children. My hobbies outside of dentistry include, hiking, backpacking, mountain biking, ultimate Frisbee, basketball and softball.


I completed my undergraduate degree at Utah State University in Logan Utah. This is also where I met my wonderful wife. We married in 2004, and have been blessed with 5 active children. I graduated Cum Laud with a degree in Biology. After undergraduate I attended dental school in Nova Scotia Canada, and graduated valedictorian. We moved back to Utah after being accepted to a dental residency at the University of Utah Hospital. I worked with many dental specialists an was able to improve in all areas of dentistry including, Implant placement and Endodontics.


My love for Arizona started after working one summer here in 2003 for the Anasazi foundation. The hot sun and magnificent desert grew on me. After my residency it didn’t take much convincing to get my wife to move here.

I am very excited that you have chosen Arizona Advanced Dental, and am looking forward to working with Dr. Clifford to serve the wonderful people of this community.
