Meet The Doctors


Dr. Berkley Hall

Dr. Berkley Hall

Doctor of Medicine in Dentistry

Dr. Hall received his Doctor of Dental Medicine from Temple University School of Dentistry in Philadelphia, PA and his Bachelor of Arts from Brigham Young University in Provo, UT. He is from Vernal, Utah, is married, and has three children. He and his family moved to Tucson in 2009.

I believe that life is what you make of it and the same can be said about your oral health. There are many options in life and it is up to each individual to find what is right for them. When it comes to practicing dentistry I like to provide options that are honest and simple in order to allow each individual the freedom to choose the best dental treatment for their needs. My focus is on preventive care, patient education, and communicating the importance of good dental health in a relaxed, comfortable environment. My ultimate goal is for each patient to fully embrace the idea they are doing what is best for their own oral health based on the recommendations I provide as their dentist.
