Location Services

As the oldest and original location, in operation since 1978, the 23rd Street Dental Depot has a rich history.


The office became a staple of the historic Linwood neighborhood after its founding by Dr. Glenn Ashmore, a Baylor College of Dentistry graduate and former member of the United States Navy Dental Corps.

Dental Depot’s presence in the Linwood community has been one of the mutual benefits. Many beautification efforts in the form of new lamp posts, benches, and seasonal landscaping of road medians have been a direct result of the office’s presence and community outreach. These efforts have resulted in accolades by the OKC Beautiful organization, a Keep America Beautiful affiliate. The practice’s central location has also been instrumental in keeping the company involved with several Oklahoma City community activities, such as the Stockyard Stampede Parade (formerly Cowboy Christmas Parade), Classen Ten Penn Community Festival, OK Kids Korral, and various other community events and organizations.

Customers Say

Originally, I got a recommendation from a co-worker to go there. That was 11 years ago. Though I am generally scared of dentists because of bad experiences in the past, that has never been a problem with Dr. Glenn Ashmore at Dental Depot. My biannual cleanings with various dental hygienists have also gone well. I love watching the various toy trains that go in and out of the various rooms. Though I don't have kids, they have a kids play area. In addition to my regular cleanings, I've had crowns replaced and one root canal. When I had a lot of pain the day following the root canal, they got me in to be seen immediately the next morning. So if I love going there after all those experiences, you know they have to be good! Also, I've recommended them to many of my co-workers who have also had great experiences. I would give them more than 5 stars if I could.

Though not related to dental work, Dental Depot does a lot to beautify the grounds around their offices. For that they have received accolades from OKC Beautiful.
