Angela Ott, D.D.S. - Owner/President of Cornerstone Dental Group

Family Dentist in Cincinnati, OH

Cornerstone Dental Group

I joined Cornerstone Dental Group in 2006 after completing my training at The Ohio State University College of dentistry . I received my undergraduate degree at the University of Tennessee Chattanooga . While at the University of Tennessee, I was a member of the Lady Mocs women's basketball team. We played in three NCAA basketball tournaments during my four years. I received my certification in Invisalign Orthodontic treatment in 2006, which is the "invisible" way of straightening teeth. I am also experienced in the latest technologies of performing root canals, CEREC same-day crowns, and oral surgery. Practicing at Cornerstone Dental Group's state of the art facility gives me the ability to reach the goal of making my patients look and feel their best.

I place the utmost value on developing relationships based on trust, honesty, and compassion. I also recognize individual fears of coming to the dentist, hence I try to ease the fear with open communication and gentle care. As a new mother, I place a strong value on my family. I am, therefore, honored to incorporate my family values into my practice by treating your entire family. I am a member of the American Dental Association , Ohio Dental Association , and Cincinnati Dental Society .

Make someone smile and you will brighten their whole day. It is contagious. This has been my motivation and why over 40 years ago I decided to go with the “smile profession.” I grew up in Columbus, Ohio, and attended Miami University of Ohio for my undergraduate studies. It was at Miami University that I met my best friend who has been my wife and partner in life for over 40 years. I attended The Ohio State University Dental School , followed by serving in the U.S. Navy Dental Corp. In 1978, we settled in Cincinnati, Ohio.

Dentistry has given me the opportunity to perform the art of healing and to make people feel better about themselves. Many people have a real fear of dental treatment, and I help reduce that fear through trust, understanding their problems, patience, and a gentle touch. It is rewarding to watch a patient’s “wowed” reaction as their tooth is being fixed with a crown designed on a computer and milled before their eyes in less than 10 minutes. Their smile is priceless. In addition to restoring teeth, I have enjoyed improving patient’s quality of life by treating their sleep apnea and snoring with an oral device instead of the cumbersome c-pap machine.

In my free time; I enjoy spending time with my 3 married children and my 5 precious grandchildren, traveling and going to the movies with my wife, playing Words with friends, and making the world a better place through my philanthropic work with Jewish National Fund . I support organized dentistry through membership in the American Dental Association , Ohio Dental Association , and Cincinnati Dental Society . I look forward to meeting you and giving you a tour of our nationally-recognized state of the art dental office.
